17 Common CrossFit injuries (Prevention & Treatment)

The CrossFit injuries that show up most: wrist and shoulder damage, lower back strain, tennis elbow, knee injuries and torn hand calluses.

High-rep work under fatigue also causes hip impingement, quadriceps and hamstring strains, IT band syndrome, plantar fasciitis and hernias, each with its causes and warning signs.

Knowledge is power, and by understanding these injuries, you can take essential steps to avoid them and stay in peak performance.

Injury Rates and Numbers

The figures below come from injury surveillance data and peer reviewed studies. Each row names the population it was measured in, because rates from elite athletes and from recreational players are not comparable.

Wrist Injuries (Sprains, Strains)

The wrist is stabilized by a set of short ligaments between the carpal bones and by the triangular fibrocartilage complex on the little finger side. In CrossFit the wrist is forced into deep extension in the front rack, the overhead squat, the push press and every handstand or burpee, and it is loaded at the end of that range rather than in the middle. Sprains involve those ligaments, while strains involve the flexor and extensor tendons that cross the joint.

Symptoms

• Pain at the front of the wrist when you catch a clean or hold the front rack.
• Pain that appears the moment your hands go on the floor for push ups or handstands.
• A dull ache on the little finger side when you rotate the forearm, for example turning a key.
• Swelling or a puffy feeling around the joint after a session.
• Weak grip, or the sense that the wrist gives way under load.

How serious it is: Sprains are graded 1 to 3: grade 1 is a stretched ligament with pain but a stable joint, grade 2 is a partial tear with more swelling and instability, grade 3 is a complete tear or a bone that has shifted position. The important distinction in practice is between a painful but stable wrist and one that clicks, gives way or cannot bear your body weight at all.

Typical time out: One to three weeks for a mild sprain or a tendon strain, six to twelve weeks for a significant ligament injury, and three months or more if a scaphoid fracture or a full ligament tear is found and treated surgically. The range is wide because wrist pain after a fall on the outstretched hand can be a simple sprain or a fracture that looks identical from the outside.

See a doctor if: Get it imaged if the wrist stays tender in the hollow at the base of the thumb after a fall, if it looks deformed, or if you cannot take your own body weight through the hand after a week of settling.

What helps

• Keep training but swap the positions that hurt: use a safety bar or straps in the front rack, do dumbbell pressing with a neutral grip, and use parallettes or dumbbell handles instead of a flat palm on the floor.
• Build wrist extension range and load it deliberately with slow controlled work on hands and knees, adding your own body weight in steps.
• Strengthen the grip and the forearm in both directions, since most gym programs load flexion only.
• Wrist wraps help in heavy overhead and front rack work, but treat them as a tool for peak load, not something worn through every session, since they take the work away from the joint.
• See a physical therapist if pain persists past three or four weeks, and get imaging earlier if the injury started with a fall rather than gradually.

Shoulder Injuries (Rotator Cuff, Labrum)

The rotator cuff is four tendons that hold the head of the upper arm bone centered in a shallow socket, and the labrum is the cartilage rim around that socket, with the long head of the biceps anchored to its top edge. CrossFit loads the shoulder at the very end of its range with high repetitions: kipping pull ups and toes to bar swing the joint under load, the snatch and the overhead squat hold it locked out with a heavy bar, and ring dips place it in a deep, unstable bottom position. The shoulder is one of the three most commonly injured regions in CrossFit athletes, at 18.4 percent of injuries in a nine month prospective cohort.

Symptoms

• Pain at the front or outer side of the shoulder when you press overhead or reach behind your back.
• A deep ache in the shoulder at night, especially lying on that side.
• Weakness or a dead arm feeling on the last reps of pull ups or presses.
• Clicking, catching or a sense that the joint slips in the bottom of a dip or the catch of a snatch.
• Loss of overhead range, so the bar drifts forward instead of stacking over the ear.

How serious it is: Rotator cuff problems run from tendinopathy with no tear, through partial thickness tears, to full thickness tears where the tendon has separated from the bone. Labral injuries range from a frayed rim that hurts but stays stable to a detached rim with true instability, and it is instability, weakness that does not recover between sessions, and night pain that separate the serious end from the manageable end.

Typical time out: Six to twelve weeks of adjusted training for tendinopathy or a small partial tear, four to six months after a labral repair, and up to nine months or more before full overhead loading after a full thickness cuff repair. The range is wide because two shoulders with identical pain can have very different tissue damage underneath.

See a doctor if: See a doctor if the arm cannot be lifted away from your side at all, if the shoulder felt like it came out and went back in, or if pain wakes you every night for more than two weeks.

What helps

• Keep loading the shoulder but change the direction: landmine and incline pressing usually stay comfortable when strict overhead work does not, and strict pull ups on rings often feel better than kipping.
• Progressive strengthening of the cuff and the muscles that control the shoulder blade, held for at least three months, is what changes tendinopathy, not stretching or massage.
• Cut kipping volume first. High repetition kipping pull ups and toes to bar load the front of the joint at the end of range while it is fatigued, and they are usually the reason the pain arrived.
• Earn overhead range before you load it: if you cannot hold a bar overhead with the ribs down and the elbows locked, scale the movement rather than working around the restriction.
• Corticosteroid injections can reduce pain in the short term, but tendon outcomes tend to be worse at a year, so treat them as an exception when pain blocks rehabilitation, not as the treatment itself.

Lower Back Injuries (Herniated Disc, Muscle Strain)

The lumbar spine carries load through the discs between the vertebrae, the small facet joints behind them, and the muscles that hold the segments in position. In CrossFit the back is loaded heavily and repeatedly in the deadlift, the clean, the kettlebell swing and the wall ball, often for time and often while fatigued, which is when the spine rounds under a bar that has not gotten any lighter. A muscle strain involves the erector spinae and the surrounding tissue, while a disc injury means the outer ring of a disc has been damaged and its inner material presses on nearby nerve roots. The lumbar spine is one of the most commonly injured regions in CrossFit, at 18.1 percent of injuries in a nine month prospective cohort.

Symptoms

• A sharp catch in the low back during or just after a heavy lift or a fast set of swings.
• Stiffness that is worst first thing in the morning and eases as you move.
• Pain that runs into the buttock, the back of the thigh or below the knee, which points at a nerve rather than muscle.
• Difficulty standing straight up, or a body that lists to one side.
• Pain when coughing, sneezing or straining, which is typical of a disc problem.

How serious it is: Most episodes are muscular or joint related, settle within weeks and carry no lasting damage. A disc injury is more serious when leg symptoms are stronger than back symptoms, when there is measurable weakness such as a foot that drags, or when numbness appears, and any loss of bladder or bowel control or numbness in the saddle area is an emergency.

Typical time out: One to three weeks for a simple strain with modified training in between, six weeks to three months for a disc injury with leg pain, and longer if weakness is present or surgery is needed. The range is wide because most of the recovery time is nerve irritation settling, not tissue healing.

See a doctor if: Go to a doctor the same day for numbness between the legs, loss of bladder or bowel control, or a leg that is clearly weak, and get assessed soon for back pain with fever or unexplained weight loss.

What helps

• Move early. Staying still beyond the first day or two makes it worse, and gentle walking plus pain free range work usually beats lying down.
• Keep lifting, at a load you can control with a neutral spine. Trap bar deadlifts, box squats to a comfortable depth and single leg work let you train while the back settles.
• Build tolerance back deliberately: hip hinge patterns without load, then light loads at low repetitions, then volume, rather than returning straight into a timed workout.
• Change the way you get fatigued. Break the metabolic sets that force a rounded back into shorter blocks, or scale the load so form stays the same at rep thirty as at rep one.
• Physical therapy is worth it if pain persists past two or three weeks. Imaging is only useful when leg symptoms, weakness or red flags are present, because scans in pain free adults are routinely full of findings.

Elbow Injuries (Tennis Elbow)

Tennis elbow is a tendinopathy of the common extensor tendon where the forearm muscles that lift the wrist and fingers attach to the bony point on the outside of the elbow. In CrossFit it comes from sustained hard gripping under load, so hanging work such as pull ups and toes to bar, heavy carries, kettlebell work and rope climbs are the usual drivers. The tendon itself becomes disorganized rather than inflamed, which is why it responds to loading rather than rest.

Symptoms

• Pain on the bony point on the outside of the elbow that you can find with one finger.
• Pain when gripping, so lifting a kettle or shaking hands hurts.
• Weak grip strength, and things slip out of the hand unexpectedly.
• Pain when straightening the elbow fully after a session.
• Soreness that eases while warm and returns worse the next morning.

How serious it is: There is no standard grading. What separates a mild case from a stubborn one is duration and how far pain has spread into everyday tasks: a few weeks of pain only during training usually settles quickly, while months of pain with daily gripping affected takes far longer and sometimes involves a partial tear at the tendon origin.

Typical time out: Six weeks to three months for most cases with the right loading, six to twelve months if it has been present for a long time before treatment started. Complete stopping does not shorten it, since the tendon needs graded load to reorganize.

See a doctor if: See a doctor if there is numbness or pins and needles in the hand, if the elbow locks or catches, or if pain came suddenly during a lift with immediate swelling and bruising.

What helps

• Progressive loading of the wrist extensors, starting with isometric holds for pain relief and moving to slow heavy work, is the treatment with the best track record.
• Reduce total gripping volume rather than training. Use straps for pulls and carries, swap high repetition kipping pull ups for ring rows or strap assisted work for a block.
• Check the grip itself. A thicker bar or a false grip changes the load on the tendon, and a grip that stays clenched between reps is doing more damage than the reps.
• A counterforce brace on the forearm can reduce pain enough to train, but it works alongside the strengthening, not instead of it.
• Corticosteroid injections give short term relief but worse results at six and twelve months in tendinopathy, so keep them as a rare exception rather than the first step, and see a physical therapist if there is no progress after six to eight weeks.

Knee Injuries (ACL, Meniscus)

The anterior cruciate ligament runs inside the knee and stops the shin bone sliding forward and rotating on the thigh bone, while the menisci are two wedges of cartilage that spread load across the joint. In CrossFit these are hurt by landings from box jumps, by the twist and knee collapse in a fatigued jumping or lunging set, and by deep squatting and heavy cleans under load. The knee is one of the three most commonly injured regions in CrossFit athletes, at 17.4 percent of injuries in a nine month prospective cohort.

Symptoms

• A pop or tearing sensation at the moment of injury, often with a feeling that the joint shifted.
• Swelling that fills the knee within a few hours, which points at bleeding inside the joint.
• The knee giving way when you turn or step down stairs.
• Locking or catching, so the knee will not fully straighten.
• Pain along the joint line that is worse when squatting deep or twisting.

How serious it is: Ligament injuries are graded 1 to 3, from stretched, through partial tear, to complete rupture. Meniscus tears range from small stable tears that settle with rehabilitation to displaced tears that physically block the joint. Rapid swelling and a knee that gives way are the two features that most reliably mark the serious end.

Typical time out: Two to six weeks for a mild sprain or a small stable meniscus tear, three to four months after a meniscus repair with restricted loading, and nine to twelve months before returning to jumping and cutting after ACL reconstruction. The range is wide because the same collapse can produce a strain or a rupture.

See a doctor if: Get assessed promptly if the knee swelled up within a few hours, if it gives way under you, if it cannot be fully straightened, or if you cannot put weight on it.

What helps

• Get an early assessment when swelling appeared within hours, because the plan for a ruptured ligament is completely different from the plan for a bruise.
• Regain full extension first. A knee that will not straighten fully is the single most common reason rehabilitation stalls.
• Structured strength work for the quadriceps, hamstrings and glutes, followed by controlled landing and change of direction training, is the path back for both surgical and non surgical cases.
• Scale the movements that caused it: step ups or lower boxes instead of high box jumps, and rebounding removed while the knee is irritated, since missed rebounds are a common way this happens.
• MRI is warranted when the joint locks, gives way or swelled immediately. Otherwise start with a clinical assessment, because scan findings in adults frequently do not match the symptoms.

Hand Injuries (Calluses, Tears)

Skin at the base of the fingers thickens into calluses under repeated shear from a bar, and when a thick callus is loaded during high repetition pull ups or toes to bar it folds and rips away, taking the layers below the surface with it. The result is an open wound over an area that has to grip, and unlike a blister there is no roof of skin to protect it.

Symptoms

• A burning or stinging sensation in the palm during high repetition bar work.
• A raised, hard ridge of skin at the base of the fingers that catches on the bar.
• A visible flap of torn skin with a raw red base underneath.
• Pain when gripping anything, including everyday objects, for several days.
• Redness spreading around the wound, warmth or discharge, which means infection.

How serious it is: A superficial tear that stays within the thickened callus heals in days. A deep tear that exposes the layer below bleeds, hurts to grip and takes one to two weeks. Any wound with spreading redness, pus or fever has become an infection and is a different problem.

Typical time out: Two to four days off bar work for a shallow tear, one to two weeks for a deep one, longer if it becomes infected. Training legs, running and pressing usually continues throughout, the restriction is on gripping.

See a doctor if: See a doctor if redness spreads from the wound, if it produces pus, if the hand becomes swollen and warm, or if you develop a fever.

What helps

• Trim the loose flap back with clean scissors rather than leaving it to catch, then clean the wound and keep it covered while it forms new skin.
• Prevent the tear before it happens by filing calluses flat with a pumice stone or file after showering, on a routine, not once the ridge is already thick.
• Use grips, tape or hand protection for high repetition bar workouts, and chalk lightly, since heavy chalk increases friction rather than reducing it.
• Change how you hold the bar. Gripping in the fingers rather than deep in the palm reduces the fold of skin that gets torn.
• Keep training everything that does not need a grip while the skin closes, rather than taking the whole week off.

Ankle Sprains

Most sprains damage the ligaments on the outside of the ankle, chiefly the anterior talofibular ligament, when the foot rolls inward under body weight. In CrossFit this happens on landings from box jumps, on missed rebounds, on the turn during shuttle runs and on the drop from a rope climb. The ligament is stretched or torn, and with it go the position sensors that tell you where the foot is, which is why a first sprain makes a second one more likely.

Symptoms

• Immediate pain on the outside of the ankle at the moment the foot rolled.
• Swelling around the ankle bone within hours, often followed by bruising into the foot.
• Difficulty putting full weight through the foot.
• A sense that the ankle is loose or unreliable on uneven ground.
• Stiffness the next morning that limits how far the knee can travel over the toes.

How serious it is: Sprains are graded 1 to 3: grade 1 is a stretched ligament with mild swelling and a stable joint, grade 2 is a partial tear with clear swelling and some instability, grade 3 is a complete tear with marked swelling and an unstable ankle. Tenderness directly on the bone rather than the soft tissue, or an inability to take four steps, raises the question of a fracture.

Typical time out: One to three weeks for a grade 1, three to six weeks for a grade 2, and eight to twelve weeks or more for a grade 3 or where a fracture is found. The main driver of the longer end is not the tear itself but how long balance and strength work is left undone.

See a doctor if: See a doctor if you cannot take four steps on it, if pain sits directly on the bone at the back edge of either ankle bone, or if the joint looks out of position.

What helps

• Start weight bearing early within pain limits. Protected early loading gives better outcomes than immobilizing the ankle.
• Balance and proprioception training, single leg work progressed to unstable and then to hopping, is what reduces the high rate of repeat sprains.
• Restore ankle dorsiflexion range, since a stiff ankle changes how you squat and land and pushes the problem up the chain.
• Strengthen the muscles on the outside of the lower leg that resist the roll, and progress back to jumping and landing in steps before returning to timed workouts.
• Tape or a brace helps in the return phase, especially in workouts involving jumping and turning, and is worth keeping for six to twelve months after a significant sprain.

Hip Injuries (Hip Impingement)

Femoroacetabular impingement means the ball and socket of the hip meet earlier than they should, because of extra bone on the neck of the femur, a deeper socket, or both. The rim of cartilage around the socket, the labrum, gets pinched at the front when the hip flexes deeply, which in CrossFit means the bottom of the squat, the catch of a clean, deep lunges, wall balls and thrusters done for high repetitions.

Symptoms

• A pinch deep in the front of the hip or groin at the bottom of a squat.
• Pain grabbed with a C shaped hand around the side of the hip, which is how people instinctively point to it.
• Stiffness after sitting for a long time, and pain getting out of a car.
• Clicking or catching in the groin during deep hip movement.
• An aching hip after squat volume rather than during it.

How serious it is: Impingement is described by shape, cam on the femoral side, pincer on the socket side, or mixed, rather than by grade. What matters practically is whether the labrum is intact, whether the pinch appears only at the very end of range or throughout the squat, and how much daily activity is affected.

Typical time out: Six weeks to three months of adjusted training for most cases treated conservatively, four to six months after arthroscopic surgery. Symptoms often improve well before the underlying shape changes, which is why the load management has to stay in place afterward.

See a doctor if: See a doctor if the hip locks or gives way, if pain wakes you at night, or if groin pain persists for months despite reducing squat depth and volume.

What helps

• Squat to the depth that does not pinch, rather than chasing full depth. A box, a slightly wider stance or a small heel lift often removes the symptom immediately.
• Strengthen the glutes and deep hip rotators, since better control of the femur in the socket reduces the pinch more reliably than stretching does.
• Stop aggressive stretching into the painful end range and stop hanging in a deep bottom position, because that is exactly where the labrum is being compressed.
• Reduce high repetition deep hip flexion under fatigue, so scale wall balls, thrusters and squat volume in the metabolic parts of the session first.
• Physical therapy first for at least three months. Imaging and a surgical opinion make sense when conservative management has genuinely been tried and the hip still locks or fails.

Quadriceps Strain

The quadriceps group runs down the front of the thigh, and the rectus femoris crosses both the hip and the knee, which makes it the part that tears most often. In CrossFit it is overloaded on the deceleration of a jump landing, in sprint starts, in high repetition lunges and box jumps late in a workout, and under the eccentric load of standing out of a heavy front squat.

Symptoms

• A sudden sharp pain in the front of the thigh during a jump, a sprint or a heavy squat.
• Pain when straightening the knee against resistance or lifting the knee up.
• Tightness and weakness going up stairs or standing from a chair.
• Bruising appearing over the thigh a day or two later in more serious tears.
• A tender spot along the muscle that you can find by pressing.

How serious it is: Strains are graded 1 to 3: grade 1 is a small number of fibers with pain but near normal strength, grade 2 is a partial tear with clear weakness and often bruising, grade 3 is a complete tear with a palpable gap and severe loss of function. A tear where the muscle meets the tendon takes markedly longer than one in the muscle belly.

Typical time out: Two to three weeks for a grade 1, four to eight weeks for a grade 2, and three months or more for a grade 3 or a tear at the tendon junction. Returning before strength matches the other leg is the main reason these injuries repeat.

See a doctor if: See a doctor if you felt a pop with immediate inability to walk, if there is a visible dent or gap in the muscle, or if the thigh becomes very swollen, hard and increasingly painful in the hours afterward.

What helps

• Start gentle pain free movement within the first days rather than resting the leg completely, since early controlled loading speeds the repair.
• Progress from isometric holds, through slow controlled work, to eccentric loading such as slow lowering in split squats and Nordic style work for the hip flexor and quadriceps.
• Build back to speed and jumping last, in steps, because most repeat injuries occur when explosive work is resumed before the muscle tolerates it.
• Keep training the rest of the body, including the uninjured leg, which helps maintain strength on the injured side.
• Get it assessed if there was a pop and immediate loss of function, or if there is no clear progress in two weeks.

Hamstring Pulls or Tears

The hamstrings run down the back of the thigh from the sitting bone to below the knee and work hardest while lengthening, at the moment the leg swings forward in a sprint and at the top of a heavy deadlift or kettlebell swing. In CrossFit they usually tear during the running portion of a workout when the legs are already fatigued from squats or swings, or during a fast, poorly controlled hinge.

Symptoms

• A sudden grabbing pain at the back of the thigh, often mid sprint.
• Pain when bending the knee against resistance or bending forward with straight legs.
• Bruising tracking down the back of the thigh over the following days.
• A deep ache at the sitting bone when sitting on a hard surface, in injuries near the top attachment.
• The leg feels unreliable when you try to accelerate.

How serious it is: Graded 1 to 3, from a minor strain with mild pain, through a partial tear with clear weakness and bruising, to a complete rupture or a tendon pulled off the sitting bone. Injuries at the upper tendon attachment take longer and are the ones most likely to need a surgical opinion.

Typical time out: Two to four weeks for a grade 1, six to twelve weeks for a grade 2, and three to six months for a complete tear or an avulsion at the sitting bone. Hamstring injuries repeat often, and the repeat rate rises sharply when the athlete returns as soon as pain disappears.

See a doctor if: See a doctor if you felt a pop with immediate difficulty walking, if there is heavy bruising and a gap you can feel near the sitting bone, or if there is numbness or shooting pain down the leg.

What helps

• Load the hamstring early in a controlled way rather than resting it. Isometric holds in the first days, then slow work through increasing range.
• Eccentric strengthening at long muscle length, Nordic curls and Romanian deadlifts done slowly, is the best supported way to reduce reinjury.
• Rebuild running in stages: walking, then jogging, then controlled strides, then full speed. Full speed is the last step, not the test of readiness.
• Check the workout design that caused it. Running placed after heavy squat or swing volume is a common setup for this injury, and reordering or scaling reduces the risk.
• Get assessed if pain sits right at the sitting bone, since upper attachment injuries follow different timelines and occasionally need surgery.

Neck Injuries (Muscle Strain)

The muscles running from the base of the skull to the upper back, chiefly the upper trapezius and the levator scapulae, hold the head steady while the arms work overhead. In CrossFit they are strained by handstand push ups, where load goes through the head and neck directly, by holding a heavy front rack where the bar sits against the throat, and by pressing overhead with the head pushed forward instead of the ribs stacked under the bar.

Symptoms

• Tight, aching pain across the top of the shoulders and the base of the neck.
• Difficulty turning the head fully to one side the morning after a session.
• Headache starting at the base of the skull.
• A specific tender spot in the muscle that reproduces the pain when pressed.
• Pain increasing over the day when working at a desk after training.

How serious it is: Simple muscular strains are painful and stiff but leave normal strength in the arms and settle within days to a couple of weeks. Nerve involvement changes the picture entirely: pain, numbness or weakness travelling down the arm suggests a nerve root is irritated, and that is neither a muscle strain nor something to train through.

Typical time out: Three days to two weeks for a muscular strain with modified training throughout, six weeks to three months if a nerve root is involved. Neck pain after a fall onto the head or a failed handstand belongs in a different category and needs assessment first.

See a doctor if: Go to a doctor for numbness, tingling or weakness in an arm or hand, for neck pain after a fall onto the head, or for neck pain with fever, severe headache or any change in consciousness.

What helps

• Keep the neck moving in the pain free range from day one. Holding it stiff prolongs the problem.
• Strengthen the deep neck flexors and the muscles that hold the shoulder blades down, which take load off the upper trapezius.
• Fix the overhead position. If the bar cannot pass over the ear without the head pushing forward, work on thoracic extension and shoulder range instead of pressing heavier.
• Scale handstand push ups to pike push ups or elevated dumbbell pressing while the neck is irritated, since direct load through the head is the aggravating factor.
• Heat and gentle movement for comfort, and physical therapy if the stiffness has not settled in two to three weeks.

Iliotibial (IT) Band Syndrome

The iliotibial band is a thick sheet of connective tissue running from the hip to just below the outside of the knee, tensioned by the gluteus maximus and the tensor fasciae latae. Pain comes from compression of the fat and tissue underneath it against the outer edge of the thigh bone as the knee bends and straightens under load, which in CrossFit means the running portions of workouts, high repetition step ups and long air squat sets.

Symptoms

• A sharp or burning pain on the outside of the knee that appears at a predictable point in a run.
• Pain worse running downhill or down stairs.
• Pain that eases quickly when you stop and returns as soon as you start again.
• Tenderness pressing just above the outer side of the knee joint.
• Occasionally a similar pain over the bony point on the outside of the hip.

How serious it is: There is no formal grading. The practical scale is whether pain appears late in a run and settles quickly, or arrives within minutes and stays afterward through walking and stairs, which marks a more irritated tissue and a longer course.

Typical time out: Two to six weeks for an early case where running volume is adjusted quickly, two to three months for one that has been pushed through for a long time. Most other training continues throughout, the restriction is on repetitive knee bending under load.

See a doctor if: See a professional if the knee swells, locks or gives way, since IT band syndrome does none of those and the diagnosis is probably wrong.

What helps

• Reduce the aggravating volume rather than stopping training: shorter run intervals, flat ground instead of downhill, and other conditioning that does not repeatedly bend the knee under load.
• Strengthen the hip abductors and the gluteus maximus, since poor control of the hip in single leg stance is the usual driver.
• Increase running cadence slightly and avoid overstriding, which reduces the compression at the knee.
• Foam rolling over the painful spot gives short term relief at best and can irritate the tissue further, so roll the glutes and quadriceps instead and rely on strength work for the actual change.
• See a physical therapist if there is no progress in four to six weeks, since the strength deficit driving it is often not obvious from the outside.

Foot Injuries (Plantar Fasciitis)

The plantar fascia is a thick band of connective tissue running from the heel bone to the base of the toes, supporting the arch and storing energy every time you push off. In CrossFit it is loaded by double unders, box jumps, running and long standing sessions, often in flat, minimally cushioned lifting shoes, and the problem is nearly always a jump in the amount of that impact work rather than a single event.

Symptoms

• Sharp heel pain on the first steps out of bed in the morning.
• Pain that eases after a few minutes of walking and returns after standing for a long time.
• Tenderness on the inner side of the heel that you can pinpoint with a thumb.
• Pain at the start of a set of double unders that warms up and then returns worse afterward.
• Stiffness in the calf and the arch, especially first thing.

How serious it is: Not graded. What separates a mild case from a stubborn one is how long it has been present and whether pain has spread from first steps in the morning to constant pain when standing, which typically means months rather than weeks of recovery.

Typical time out: Six weeks to three months for a case caught early, six to twelve months if it has been present for a long time. Impact work is what has to be reduced, and most strength training continues throughout.

See a doctor if: See a doctor if the heel pain started suddenly with a pop, if there is numbness or burning spreading into the foot, or if heel pain persists at rest and at night.

What helps

• Progressive high load strength work for the calf and the arch, heel raises with the toes elevated on a towel, done slowly, has the best evidence for changing this.
• Cut jumping volume for a block. Fewer double unders, lower boxes, and step downs instead of rebounding, then rebuild the volume in steps.
• Add cushioning where the impact happens. Training shoes rather than flat lifting shoes for the conditioning parts, and supportive footwear during the day, especially if you stand at work.
• Calf flexibility work and a short morning routine before the first steps out of bed, which reduces the sharpest pain of the day.
• See a professional if there is no improvement after two to three months, since heel pain with burning or numbness is often a nerve problem instead and needs a different plan.

Rib Injuries (Costochondritis)

Costochondritis is inflammation of the cartilage that joins the ribs to the breastbone. In CrossFit the front rack of a clean and the bar position in a heavy front squat press directly onto the upper ribs, and the repeated forceful trunk flexion of toes to bar and sit ups plus deep hard breathing under fatigue keeps loading the same joints. The pain is real and reproducible by pressing, which is what distinguishes it from other causes of chest pain.

Symptoms

• Sharp pain at the front of the chest beside the breastbone, worse with a deep breath.
• Tenderness you can reproduce by pressing on the affected spot.
• Pain when the bar sits in the front rack, or when rolling over in bed.
• Pain with coughing, sneezing or laughing.
• Discomfort that spreads along the rib rather than sitting in one point deep inside.

How serious it is: Not graded. Mild cases are uncomfortable only under direct pressure and during hard breathing, while more irritated cases hurt with everyday movement and sleep. Chest pain that cannot be reproduced by pressing, or that comes with shortness of breath, sweating or dizziness, is not this diagnosis and needs urgent medical assessment.

Typical time out: Two to six weeks for most cases with adjusted training, up to three months if it keeps being reloaded. A rib stress injury or a fracture from a direct blow is a separate problem and takes six weeks or more.

See a doctor if: Call for emergency help for chest pain with shortness of breath, sweating, dizziness or pain spreading into the jaw or arm, since that is not a training injury until proven otherwise.

What helps

• Take direct pressure off the ribs: use straps and a hang or dumbbell variation instead of the barbell front rack, and back squat instead of front squat for a block.
• Reduce high repetition trunk flexion, so scale toes to bar, sit ups and heavy wall ball volume while it settles.
• Gentle thoracic mobility and breathing work, keeping the rib cage moving rather than guarding it, which tends to prolong the pain.
• Heat and short term pain relief make it easier to sleep and to keep moving, and sleep position matters more than most people expect.
• Get a medical assessment if the pain followed a direct blow or a fall, if it does not settle over several weeks, or if it is accompanied by breathlessness.

Hernia

A hernia is a weak point in the abdominal wall through which fat or bowel pushes out, most commonly in the groin at the inguinal canal, or at the navel. In CrossFit the pressure inside the abdomen rises sharply during heavy deadlifts, cleans and overhead lifts, especially with a held breath, and that pressure is what forces tissue through an area that is already weak. Straining under fatigue at the end of a workout is the classic circumstance.

Symptoms

• A soft bulge in the groin or at the navel that appears when you strain and often disappears when you lie down.
• A dragging or heavy sensation in the groin that worsens through the day.
• Pain when lifting, coughing or straining.
• Aching that improves with rest and returns with the next heavy session.
• In a groin hernia, discomfort spreading toward the upper thigh or scrotum.

How serious it is: A reducible hernia, one that can be pushed back in or disappears when lying down, is not an emergency and is often managed with observation or planned surgery. A hernia that becomes stuck, hard and tender, with nausea, vomiting or a sudden increase in pain, may have trapped its blood supply and is a surgical emergency.

Typical time out: Ongoing training with modification if the hernia is small and reducible, four to six weeks after keyhole repair before light training resumes, and three months or more before heavy lifting after an open repair. The surgeon sets the timeline, and it varies by technique.

See a doctor if: Go to an emergency department if a bulge becomes hard, tender and cannot be pushed back in, or if it comes with nausea, vomiting or severe pain.

What helps

• Get any new groin or navel bulge examined rather than training around it, since a hernia does not resolve on its own.
• Adjust the breathing and bracing pattern under heavy load and stop maximal straining while it is being assessed.
• Keep training with lighter loads and controlled breathing where a surgeon has agreed it is safe, since staying strong helps recovery afterward.
• After a repair, follow the surgeon’s loading schedule and rebuild pressing, deadlifting and high repetition trunk work in steps rather than going straight back to timed workouts.
• Be aware that persistent deep groin pain without a bulge is more often a muscle or tendon problem in the groin than a hernia, and needs a different assessment.

First Aid for Soft Tissue Injuries: PEACE and LOVE

Sports medicine has moved on from RICE. The current guidance, published in the British Journal of Sports Medicine in 2019, splits care into the first days after the injury and everything that follows.

PEACE, the first two to three days

• Protect: unload the area and limit movement that hurts, but only briefly.
• Elevate: keep the limb above heart level when you can.
• Avoid anti-inflammatories: they may blunt the healing you need.
• Compress: a bandage or taping limits swelling.
• Educate: your body heals this on its own; passive treatments rarely speed it up.

LOVE, from day three onward

• Load: return to movement as pain allows, early loading builds tissue.
• Optimism: expectations shape recovery more than most people assume.
• Vascularization: easy cardio that does not hurt brings blood to the area.
• Exercise: restore strength, mobility and balance before returning to play.

Ice still helps with pain in the first hours. What changed is the evidence that long icing and routine anti-inflammatory drugs slow tissue repair.

How to Lower Your Risk in Crossfit

• Add training hours gradually rather than in jumps. In a nine month prospective cohort of CrossFit athletes, each additional weekly training hour raised injury risk by 35 percent, which makes weekly volume the single most controllable factor in this sport.
• Finish rehabilitation before you return to full intensity. Athletes in that same cohort who had a previous injury were 3.92 times more likely to sustain a new one, so an old shoulder or back that still complains under load is a prediction, not a nuisance.
• Scale the weight in timed workouts so that the last repetition looks like the first. Overuse problems made up 49.2 percent of injuries among injured athletes in a Czech survey, and they accumulate from repetitions performed with a spine or shoulder that has already given up its position.
• Protect the three regions that carry most of the risk. Shoulder, lumbar spine and knee were the most commonly injured areas in the prospective cohort, so dedicated strength work for the rotator cuff and scapula, the hip hinge and the quadriceps and hamstrings belongs in every week.
• Keep kipping volume, box jump rebounding and double under volume as deliberate decisions rather than defaults. These three movements produce the shoulder, knee, ankle and heel problems that fill this list, and they are the easiest to scale without losing the workout.
• Practice heavy technical positions while fresh, in strength sessions, rather than learning them under a running clock. A clean caught in a poor position at repetition thirty of a metabolic workout is where most acute injuries in this sport begin.

When to Stop and Get Medical Help

Most of the injuries on this page are treated at home. These signs are not.

• Any blow to the head, or confusion, memory gap, repeated vomiting or loss of consciousness after a fall from a rope, a bar or a handstand. Stop for the day and get assessed even if you feel fine within minutes.
• Numbness, tingling or weakness in an arm or leg, or numbness between the legs with loss of bladder or bowel control, which is a same day emergency.
• A joint that looks out of position, will not move, locks, or gives way when you try to load it.
• Inability to put weight on a leg after a landing, or pinpoint tenderness directly on a bone, both of which suggest a fracture.
• Chest pain with shortness of breath, sweating or dizziness, which needs emergency assessment rather than the assumption of a rib or muscle problem.
• A groin or navel bulge that becomes hard, tender and cannot be pushed back in, particularly with nausea or vomiting.
