Hypertrophy/Injuries

Injury Modifications

8 injury guides

Guidelines for safely modifying workouts when dealing with common injuries. Always consult a healthcare professional for specific medical advice.

Elbow Tendinopathy

Elbow tendinopathy is common in hypertrophy training due to the high volume of gripping, curling, and pressing that loads the forearm tendons at their attachment points on the elbow. The two main presentations are lateral epicondylitis (tennis elbow, pain on the outside of the elbow from wrist extensor overload) and medial epicondylitis (golfer's elbow, pain on the inside of the elbow from wrist flexor and pronator overload). In lifters, lateral epicondylitis typically flares from heavy pulling (rows, deadlifts, pull-ups) and excessive grip work, while medial epicondylitis is aggravated by curling, pressing, and anything requiring strong grip with forearm pronation. Both respond well to load management, eccentric strengthening, and grip modification rather than complete rest.

Conditions Covered

lateral_epicondylitismedial_epicondylitiscommon_extensor_tendinopathycommon_flexor_tendinopathy

Warning Signs

  • Pain that worsens during the workout instead of improving with warm-up
  • Grip strength decreasing over consecutive sessions
  • Pain radiating down the forearm from the elbow
  • Clicking or catching sensation at the elbow with pain
  • Swelling visible or palpable at the epicondyle
  • Numbness or tingling in the fingers (possible nerve involvement, different from tendinopathy)

Red Flags - Seek Immediate Care

  • Sudden inability to straighten the elbow after a pop or snap. Possible tendon rupture. Seek immediate evaluation.
  • Visible deformity or significant swelling after trauma. Possible fracture or dislocation. Seek emergency care.
  • Numbness or tingling in ring and small fingers. Possible ulnar nerve compression (cubital tunnel). Seek evaluation.
  • Numbness in thumb, index, and middle fingers combined with elbow pain. Possible nerve involvement. Seek evaluation.
  • Fever with a red, hot, swollen elbow. Possible infection or septic joint. Seek immediate care.
  • Locking of the elbow joint. Possible loose body. Seek orthopedic evaluation.

When to Seek Professional Care

  • Any red flag symptoms
  • Elbow pain not improving after 4-6 weeks of modification and rehabilitation
  • Numbness or tingling in fingers (nerve involvement requires different treatment)
  • Pain after a traumatic event (fall on outstretched hand, direct impact)
  • Progressive weakness in grip despite consistent rehabilitation
  • Locking, catching, or inability to fully extend the elbow

General Principles

  • Tendons respond to progressive loading, not rest. Complete rest delays healing. Load within pain-free range.
  • Distinguish lateral (outside) vs. medial (inside) elbow pain. They are aggravated by different movements.
  • Lateral epicondylitis: aggravated by wrist extension, gripping, and supination under load. Modify pulling grip.
  • Medial epicondylitis: aggravated by wrist flexion, pronation, and curling. Modify curling and pressing grip.
  • Reduce total volume before eliminating exercises. Often the cumulative volume, not one exercise, is the trigger.
  • Eccentric wrist exercises are the gold standard rehabilitation. Begin early and progress gradually.

Contraindicated Movements

Straight-bar curls with heavy load (medial epicondylitis)Reverse curls with heavy load (lateral epicondylitis)Wrist curls under heavy loadBehind-the-back wrist curlsNarrow-grip chin-ups with heavy load (medial epicondylitis)Any exercise causing sharp pain at the elbow

Recommended Exercises

Reverse of the standard Tyler Twist. Targets the common flexor tendon for golfer's elbow.

Wrist Pronation/Supination with Hammer

2 sets × 12 reps

Holds a hammer by the handle and rotates the forearm. Strengthens the forearm rotators that support the elbow.

Forearm Extensor Stretch

3 sets × reps

Straighten arm, pull fingers down with opposite hand. Stretches the wrist extensors to reduce tension at the lateral epicondyle.

Return to Full Training

  • Pain-free gripping during daily activities for 2+ weeks
  • Full grip strength restored
  • Can perform EZ-bar curls at moderate load without pain
  • No tenderness on palpation of the epicondyle
  • Can fully straighten and bend the elbow without pain

Progression:

  1. 1.Week 1-2: Eccentric wrist exercises daily. Eliminate all aggravating movements. Use machines and straps.
  2. 2.Week 3-4: Reintroduce neutral-grip exercises (hammer curls, neutral pulldowns). Straps for all pulling.
  3. 3.Week 5-6: Add EZ-bar curls at 50% normal load. Reintroduce free-weight pressing.
  4. 4.Week 7-8: Progress to normal curl and pressing load with modified grip. Maintain straps for heavy pulling.
  5. 5.Week 9-10: Cautious reintroduction of straight barbell work at reduced load.
  6. 6.Week 11+: Gradual return to full program. Continue eccentric wrist exercises as prehab permanently.

Hip Impingement

Hip impingement (femoroacetabular impingement, FAI) occurs when abnormal contact between the femoral head and the acetabulum restricts hip range of motion and causes pain during deep flexion. In hypertrophy training, this presents as pinching or sharp pain in the front of the hip during deep squats, leg presses, and any movement requiring deep hip flexion. There are two types: cam (extra bone on the femoral head), pincer (extra bone on the acetabular rim), or combined. FAI is common in heavy squatters and is often the underlying cause of chronic "hip flexor" pain that does not respond to stretching. Management focuses on limiting end-range hip flexion under load, finding pain-free squat depths and stance widths, and strengthening hip stabilizers.

Conditions Covered

femoroacetabular_impingement_camfemoroacetabular_impingement_pincerfemoroacetabular_impingement_combinedhip_labral_irritationanterior_hip_impingement

Warning Signs

  • Pinching or catching that worsens during the workout
  • Groin pain that takes more than 48 hours to resolve after training
  • Clicking in the hip with associated pain (painless clicking alone is often benign)
  • Progressive loss of hip range of motion
  • Compensating by shifting weight to one side during squats

Red Flags - Seek Immediate Care

  • Sudden sharp pain with inability to bear weight. Possible labral tear or stress fracture. Seek evaluation.
  • Locking of the hip joint. Possible loose body. Seek orthopedic evaluation.
  • Groin pain with fever. Possible infection. Seek immediate care.
  • Pain after a fall or trauma with inability to move the hip. Possible fracture. Seek emergency care.
  • Progressive numbness in the front of the thigh (possible femoral nerve involvement). Seek evaluation.

When to Seek Professional Care

  • Any red flag symptoms
  • Hip pain not improving after 6 weeks of modification and rehabilitation
  • Locking, catching, or giving way of the hip
  • Progressive loss of hip range of motion despite modification
  • Pain that significantly affects daily activities and sleep
  • If FAI is suspected, imaging (X-ray and/or MRI) can confirm the diagnosis and guide management

General Principles

  • Depth is not mandatory. A squat to parallel or above can still build quads and glutes effectively.
  • Do NOT stretch into the pinch. Hip flexor stretching often worsens FAI by forcing the femur into the impingement zone.
  • Stance width matters. A wider stance with toes turned out often clears the impingement by changing the femur-acetabulum contact angle.
  • Strengthen hip external rotators and glute medius. Weak hip stabilizers worsen impingement symptoms.
  • Box squats are your friend. They enforce consistent, pain-free depth and remove the bounce at the bottom.
  • Leg press can be worse than squats for FAI if the sled is lowered too deep. Control the depth.

Contraindicated Movements

Deep squats below parallel (ass-to-grass) under loadFull-depth leg press where the knees approach the chestDeep lunges where the hip flexes past 90 degreesSumo deadlift with extreme hip abduction (if it causes pinching)Hip flexor stretches that force end-range flexion (couch stretch, deep pigeon)Any movement causing sharp pinching in the front of the hip

Supine Hip Internal Rotation Stretch (gentle)

2 sets × reps

Gently maintains hip internal rotation range. Do not force through pain. Stop if pinching occurs.

Single-Leg Glute Bridge

3 sets × 12 reps

Hip extension strength without hip flexion loading. Addresses glute weakness that contributes to impingement.

Return to Full Training

Criteria:

  • Pain-free in daily activities (walking, sitting, stairs) for 2+ weeks
  • Can perform bodyweight squat to parallel without pinching
  • Hip internal rotation range improved or maintained
  • Glute medius strength adequate (can hold single-leg stance for 30+ seconds without hip drop)

  3. 3.Week 5-6: Introduce box squat to a comfortable height (above parallel if needed).
  4. 4.Week 7-8: Lower box squat depth gradually toward parallel. Add light barbell squat.
  5. 5.Week 9-10: Progress barbell squat load at pain-free depth. Maintain hip stabilizer work.
  6. 6.Week 11+: Return to full program at individually appropriate depth. Deep squatting may never be appropriate for some FAI anatomy.

Knee Pain

Knee pain is common in hypertrophy training due to the high volume of squatting, lunging, and leg press work that loads the knee joint through large ranges of motion. The two most common presentations in lifters are anterior knee pain (patellar tendinopathy, patellofemoral pain syndrome) and medial/lateral knee pain (meniscus irritation, collateral ligament strain, IT band syndrome). These require different modification strategies. Anterior knee pain responds well to load management and eccentric strengthening. Medial and lateral knee pain may require range of motion restrictions and stability work. Most knee pain in hypertrophy athletes is overuse-related and responds to intelligent modification rather than complete rest.

Conditions Covered

patellar_tendinopathypatellofemoral_pain_syndromemeniscus_irritationmedial_collateral_ligament_strainlateral_collateral_ligament_strainiliotibial_band_syndromeanterior_knee_pain

Warning Signs

  • Swelling that increases after training (effusion visible or palpable)
  • Knee locking or catching during movement (possible meniscus involvement)
  • Knee giving way or feeling unstable (possible ligament involvement)
  • Pain that does not improve with warm-up
  • Grinding or crepitus with pain (some painless crepitus is normal and benign)
  • Pain that worsens with each training session rather than stabilizing

Red Flags - Seek Immediate Care

  • Knee locked in position, unable to straighten or bend. Possible bucket handle meniscus tear. Seek immediate orthopedic evaluation.
  • Gross instability or knee giving way during normal walking. Possible ACL or PCL rupture. Urgent evaluation needed.
  • Large, rapid swelling within hours of an injury or event. Possible hemarthrosis (bleeding in the joint). Seek care.
  • Inability to bear weight after a traumatic event. Possible fracture or major ligament injury.
  • Fever with a swollen, hot, red knee. Possible septic joint. EMERGENCY. Seek immediate care.
  • Pop felt during a movement followed by immediate swelling. Possible ligament tear. Seek evaluation.

When to Seek Professional Care

  • Any red flag symptoms (listed above)
  • Knee pain not improving after 4-6 weeks of modification and rehabilitation
  • Recurrent effusion (swelling) after training sessions
  • Knee instability or giving way during daily activities
  • Pain after a traumatic event (twist, fall, direct impact)
  • Mechanical symptoms (locking, catching, clicking with pain)

General Principles

  • Distinguish anterior vs. medial/lateral knee pain. They require different approaches.
  • Patellar tendinopathy responds to progressive loading, not rest. Eccentric work is the gold standard.
  • Avoid deep knee flexion (beyond 90 degrees) during acute phases. Reintroduce depth gradually.
  • Quad strength is protective. Weakness of the VMO (vastus medialis obliquus) contributes to patellar tracking issues.
  • Control knee valgus (inward collapse). If the knee caves inward during squats, address hip abductor and external rotator weakness.
  • Reduce total lower body volume before eliminating exercises entirely. Volume is often the aggravating factor, not the exercise itself.

Contraindicated Movements

Deep squats below 90 degrees (during acute phase)Full-depth leg press with heavy load (during acute phase)Walking lunges with heavy load (moderate and severe)Jump squats and plyometrics (moderate and severe)Leg extension with heavy load at full range (can aggravate patellar tendinopathy)Sissy squats (extreme patellar tendon loading)Any exercise causing sharp, catching, or locking pain

Side-Lying Hip Abduction (Clamshell)

3 sets × 15 reps

Strengthens gluteus medius to prevent knee valgus during squatting movements.

Single-Leg Glute Bridge

3 sets × 12 reps

Glute and hamstring activation without knee loading. Addresses hip weakness that contributes to knee stress.

Foam Roll Quads and IT Band

sets × reps

Reduces tension in the quadriceps and IT band that can contribute to patellar tracking issues and lateral knee pain.

Return to Full Training

Criteria:

  • Pain-free during daily activities (walking, stairs, sitting) for 2+ weeks
  • No swelling after modified training sessions
  • Can perform bodyweight squat to 90 degrees without pain

  3. 3.Week 5-6: Increase leg press ROM gradually, add goblet squat to parallel
  4. 4.Week 7-8: Progress to barbell squat at 50% normal load, controlled depth to parallel
  5. 5.Week 9-10: Gradual return to full depth and normal loading
  6. 6.Week 11+: Return to full program. Maintain quad and hip strengthening permanently.

Lower Back Pain

Lower back pain is the most prevalent musculoskeletal complaint among regular gym users performing hypertrophy training. It typically arises from excessive spinal loading during compound lifts (deadlifts, squats, rows), poor bracing technique, or accumulated fatigue from high training volume. Causes range from muscular strain and facet joint irritation to disc bulges and nerve compression. Unlike the general lower_back.yaml file which covers broad lower back issues, this file provides specific substitution protocols for common hypertrophy training exercises and emphasizes core stability rehabilitation as the primary recovery pathway. Most non-traumatic lower back pain in lifters responds well to modified training rather than complete rest.

Conditions Covered

mechanical_lower_back_painlumbar_muscle_strainfacet_joint_irritationdisc_bulgedisc_herniationsciatica

Warning Signs

  • Pain that worsens during the workout instead of improving with warm-up
  • Pain persisting more than 48 hours after a training session
  • Morning stiffness getting worse over consecutive days
  • New or increasing radiating pain into buttock or leg
  • Need for pain medication before training
  • Compensatory movement patterns (shifting weight, twisting to avoid pain)

Red Flags - Seek Immediate Care

  • Loss of bladder or bowel control. CAUDA EQUINA EMERGENCY. Go to emergency room immediately.
  • Saddle anesthesia (numbness in groin, inner thighs, or perineum). EMERGENCY. Seek immediate care.
  • Progressive weakness in legs or feet (foot drop, difficulty walking on toes or heels). Possible nerve damage. Urgent evaluation needed.
  • Numbness or tingling in both legs simultaneously. Possible spinal cord or cauda equina involvement. Seek immediate care.
  • Fever with back pain. Possible spinal infection. Seek care immediately.
  • Severe pain after significant trauma (fall, car accident, heavy training accident). Possible fracture. Imaging needed.
  • Unexplained weight loss with persistent back pain. Seek medical evaluation to rule out serious pathology.

When to Seek Professional Care

  • Any red flag symptoms (listed above). Do not wait.
  • Radiating pain below the knee (sciatica) that does not improve within 2 weeks
  • No improvement after 4-6 weeks of consistent modification and rehabilitation
  • Progressive weakness in legs
  • History of cancer, significant trauma, or prolonged steroid use with new back pain
  • Back pain in an athlete under 18 (rule out spondylolisthesis)

General Principles

  • Movement is medicine. Complete bed rest worsens most lower back pain. Stay active within pain-free limits.
  • Avoid repeated spinal flexion under load. This is the primary injury mechanism in lifters.
  • Core stability (anti-extension, anti-rotation, anti-lateral flexion) is the foundation of recovery.
  • Train later in the day when possible. Discs are most hydrated and vulnerable in the first 1-2 hours after waking.
  • Neutral spine under load is protective. Learn and practice proper bracing technique.
  • Pain is not always damage. Mild discomfort during modified training is acceptable. Sharp or radiating pain is not.

Contraindicated Movements

Barbell deadlift from floor (moderate and severe)Good mornings with significant loadHyperextensions under heavy loadJefferson curlsSit-ups and crunches (spinal flexion under load)Seated exercises that force lumbar flexion (poorly adjusted machines)Any exercise causing sharp pain or pain radiating into the legs

Progression:

  1. 1.Week 1-2: Core stability exercises only (McGill Big 3: curl-up, side plank, bird-dog)
  2. 2.Week 3-4: Add supported exercises (leg press, chest-supported row, machine pressing)
  3. 3.Week 5-6: Add goblet squat and trap bar deadlift from elevated position (blocks)
  4. 4.Week 7-8: Progress trap bar deadlift to floor, add light RDL
  5. 5.Week 9-10: Gradual return to barbell squat and deadlift at 50% normal load
  6. 6.Week 11-12: Progressive loading back to normal weights. Maintain core work permanently.

Pec Strain

Pectoral strains are a significant injury in hypertrophy training, typically occurring during heavy bench pressing, dumbbell flyes, or dips when the muscle is loaded at its most stretched position. The pec major has two heads (clavicular and sternal) and most strains occur at the musculotendinous junction of the sternal head, near the shoulder. Strains range from minor fiber disruption (Grade I) to complete rupture (Grade III, surgical emergency). Grade I and II strains are manageable with modified training and progressive return-to-pressing. The critical principle is that pressing too early or too aggressively is the most common cause of re-injury. A structured, patient return is essential.

Conditions Covered

pec_major_strain_grade_1pec_major_strain_grade_2pec_minor_strainmusculotendinous_junction_strain

Warning Signs

  • Sharp pain during any pressing attempt (stop immediately)
  • Pain that worsens with each progressive session instead of improving
  • Swelling or bruising that returns after it had resolved
  • Apprehension or instability feeling when loading the pec
  • Asymmetry in pec appearance (one side notably different shape)

Red Flags - Seek Immediate Care

  • Audible pop during exercise with immediate pain and bruising. Possible pec rupture. Seek immediate evaluation.
  • Visible deformity or bunching of the pec muscle toward the center of the chest. Possible tendon avulsion. Seek immediate care.
  • Extensive bruising spreading to armpit, bicep, and forearm. Suggests significant muscle or tendon damage.
  • Complete inability to press or bring the arm across the body. Possible complete rupture. Surgical evaluation needed.

When to Seek Professional Care

  • Any red flag symptoms (suspected Grade III or rupture)
  • Bruising that is extensive or spreading
  • No improvement after 3-4 weeks of rest and modification
  • Visible asymmetry between left and right pec
  • Pain after a specific traumatic event (felt a pop, sudden sharp pain)

General Principles

  • No pressing through pain. A pec strain that is re-aggravated takes 2-3x longer to heal than the original.
  • Avoid the deep stretch position under load. This is where most pec strains occur and recur.
  • Machine pressing before free weight pressing. Fixed path machines allow pressing without stabilization demand.
  • Progress load very gradually. Add 5-10% per week during return-to-pressing, not per session.
  • Maintain pulling work. Rows, pulldowns, and rear delt work can continue and help maintain upper body balance.
  • Isometric pressing (pushing against an immovable surface) is a safe early step to test the pec.

Contraindicated Movements

Any pressing movement during acute phase (first 1-2 weeks for Grade I, 2-4 weeks for Grade II)Dumbbell flyes with deep stretchCable flyes with deep stretchDips (loaded stretch on the pec at the bottom)Barbell bench press with wide gripAny chest exercise causing pain or apprehension

Recommended Exercises

Isometric Chest Press (push against wall or doorframe)

3 sets × reps

Safe early test of the pec. Pain during isometric pressing at light effort means the strain is still acute.

Band-Resisted Push-Up (light band)

3 sets × 10 reps

Bodyweight pressing with controlled ROM. Good bridge between machine pressing and free weights.

Pec Stretch (gentle doorway stretch)

2 sets × reps

Gentle stretching after the acute phase (not during). Maintains pec flexibility during recovery. Stop if painful.

Prone Y-T-W Raises

3 sets × 10 reps

Maintains upper back and shoulder stability while the pec heals. Helps prevent posture imbalance from avoiding pressing.

Return to Full Training

Criteria:

  • Pain-free in daily activities (pushing doors, reaching overhead) for 2+ weeks
  • Isometric pressing at 70% perceived effort is pain-free
  • Machine chest press at moderate load is pain-free through full ROM
  • No tenderness on palpation of the pec
  • No apprehension (fear of re-injury) during pressing

Progression:

  1. 1.Week 1-2 (acute): No pressing. Ice 15 min 3x/day if swollen. Gentle ROM (arm circles, pendulum swings). Continue pulling work.
  2. 2.Week 3-4: Isometric pressing against wall (3 x 10s at 50% effort). Machine chest press at very light load if pain-free.
  3. 3.Week 5-6: Machine chest press at moderate load. Band-resisted push-ups. No deep stretch.
  4. 4.Week 7-8: Introduce floor press with light load. Dumbbell press (not past chest level).
  5. 5.Week 9-10: Progress to full-range barbell bench press at 50% normal load. Moderate grip width.
  6. 6.Week 11-12: Gradual return to normal pressing load. Add 5-10% per week maximum.
  7. 7.Week 13+: Return to full program. Flyes and dips should be the last exercises reintroduced, with caution.

Shoulder

Shoulder issues are common in hypertrophy training due to the high volume of pressing movements and the vulnerability of the shoulder's complex anatomy. This includes impingement, rotator cuff strains, labral issues, and biceps tendinopathy. Most shoulder problems in lifters stem from training imbalances (too much pressing, not enough pulling/external rotation) and can be managed with smart modifications.

Warning Signs

  • Pain that worsens through workout instead of warming up
  • Clicking or catching with pain
  • Weakness that doesn't improve with warm-up
  • Night pain or sleep disruption
  • Pain spreading down arm

Red Flags - Seek Immediate Care

  • Sudden loss of strength after traumatic event - possible rotator cuff tear
  • Unable to raise arm above horizontal - possible complete tear
  • Visible deformity after injury - possible dislocation
  • Numbness or tingling in arm/hand - possible nerve involvement
  • Fever with shoulder pain - possible infection

When to Seek Professional Care

  • No improvement after 4-6 weeks of modification
  • Any red flag symptoms
  • Pain after traumatic event (fall, sudden load)
  • Progressive weakness
  • Sleep significantly disrupted by pain

General Principles

  • Most shoulder issues improve with balanced programming (more pulling than pushing)
  • Pain-free range of motion work helps healing; complete rest often makes shoulders worse
  • External rotation strength is protective and often deficient
  • Avoid impingement-provoking positions (behind-neck press, upright rows)
  • Temporary exercise modification is better than complete cessation
  • Shoulders heal slowly—expect 6-12 weeks for significant improvement

Contraindicated Movements

Behind-the-neck pressUpright rows with narrow gripWide-grip bench press (for most shoulder issues)Dips (if painful)Any exercise causing sharp pain

Recommended Exercises

Face Pulls

3 sets × 15-20 reps

Strengthens external rotators and rear delts, counters internal rotation dominance

Return to Full Training

Criteria:

  • Pain-free in daily activities for 2+ weeks
  • Full range of motion restored
  • Can perform modified pressing without pain

  1. 1.Week 1-2: Pain-free ROM exercises, prehab only
  2. 2.Week 3-4: Add pulling exercises, light machines only
  3. 3.Week 5-6: Add modified pressing (floor press, machines)
  4. 4.Week 7-8: Progress to free weight pressing with conservative load
  5. 5.Week 9+: Gradual return to full program with maintained prehab

Shoulder Impingement

Shoulder impingement occurs when the supraspinatus tendon and subacromial bursa are compressed between the humeral head and the acromion during overhead or abducted arm movements. In hypertrophy training, this is commonly caused by excessive overhead pressing volume, internally rotated pressing positions, and imbalance between anterior and posterior shoulder musculature. Impingement is among the most common shoulder complaints in regular gym users, affecting an estimated 20-30% of lifters at some point. Unlike the general shoulder.yaml file which covers broad shoulder issues, this file focuses specifically on subacromial impingement and its management during hypertrophy training.

Conditions Covered

subacromial_impingementexternal_impingementsupraspinatus_tendinopathysubacromial_bursitis

Warning Signs

  • Catching or clicking sensation with pain during pressing
  • Pain that worsens through the workout instead of improving with warm-up
  • Night pain that disrupts sleep
  • Compensatory shrugging during any pressing movement
  • Pain radiating into the upper arm or toward the elbow

Red Flags - Seek Immediate Care

  • Sudden loss of shoulder strength after a traumatic event (fall, heavy failed rep). Possible rotator cuff tear. Seek immediate evaluation.
  • Complete inability to raise arm above horizontal. Possible complete rotator cuff rupture.
  • Visible shoulder deformity after injury. Possible dislocation or AC joint separation.
  • Numbness or tingling in arm or hand. Possible nerve involvement. Seek care.
  • Fever with shoulder pain and swelling. Possible infection. Seek care immediately.

When to Seek Professional Care

  • No improvement after 6 weeks of consistent modification and rehab
  • Any red flag symptoms
  • Pain after a traumatic event (fall, sudden load, failed heavy rep)
  • Progressive weakness in the shoulder
  • Sleep significantly disrupted by shoulder pain for more than 2 weeks

General Principles

  • Impingement is a positional problem. Avoid positions that close the subacromial space.
  • Increase the ratio of pulling to pushing. Target at least 2:1 pull-to-push volume.
  • Pain-free movement is therapeutic. Complete rest often worsens outcomes.
  • Strengthen the rotator cuff (especially external rotators) to improve humeral head control.
  • Address thoracic spine mobility. A stiff thoracic spine forces the shoulder to compensate overhead.
  • Scapular stability is as important as rotator cuff strength. Train serratus anterior and lower traps.

  • External rotation strength symmetrical between sides
  • No painful arc during slow shoulder abduction

Progression:

  1. 1.Week 1-2: Rotator cuff and scapular stability exercises only (rehab focus)
  2. 2.Week 3-4: Add horizontal pulling (rows) and light machine pressing
  3. 3.Week 5-6: Add incline pressing (30 degrees), neutral-grip pull-ups
  4. 4.Week 7-8: Introduce landmine press and higher incline angles
  5. 5.Week 9-10: Cautious return to overhead pressing with light load, high reps
  6. 6.Week 11+: Gradual return to full program with maintained prehab. Keep 2:1 pull-to-push ratio permanently.

Wrist Tendinopathy

Wrist tendinopathy is common in hypertrophy training due to the repetitive wrist loading inherent in curls, pressing movements, and gripping exercises. The two most common presentations are de Quervain tenosynovitis (pain on the thumb side of the wrist) and wrist extensor tendinopathy (pain on the back of the wrist during gripping). Hypertrophy training is particularly problematic because the high volume and variety of grip-dependent exercises means the wrist tendons are loaded across nearly every workout. Straight-bar curls with forced supination and heavy pressing with excessive wrist extension are the most common aggravating movements. Most wrist tendinopathy in lifters responds well to exercise modification and progressive wrist strengthening once the acute inflammation subsides.

Warning Signs

  • Pain that worsens through the workout instead of improving with warm-up
  • Swelling visible or palpable along wrist tendons
  • Grip strength decreasing over consecutive sessions
  • Clicking, snapping, or catching sensation in the wrist with pain
  • Pain radiating up the forearm from the wrist
  • Numbness or tingling in fingers (possible nerve compression, different from tendinopathy)

Red Flags - Seek Immediate Care

  • Sudden onset wrist deformity after a fall or heavy load. Possible fracture (scaphoid or distal radius). Seek immediate imaging.
  • Numbness or tingling in thumb, index, and middle fingers. Possible carpal tunnel syndrome. Seek evaluation.
  • Numbness in ring and small fingers. Possible ulnar nerve compression (Guyon canal). Seek evaluation.
  • Visible lump growing on the wrist (possible ganglion cyst). Seek evaluation.
  • Fever with a swollen, red, hot wrist. Possible infection. Seek immediate care.
  • Wrist locked in position, unable to move. Possible dislocation or fracture. Seek emergency care.

When to Seek Professional Care

  • Any red flag symptoms
  • Wrist pain not improving after 4-6 weeks of modification and rehabilitation
  • Numbness or tingling in fingers (nerve involvement requires different treatment)
  • Pain after a traumatic event (fall on outstretched hand, heavy drop)
  • Progressive weakness in grip despite rest and modification
  • Clicking or locking in the wrist joint

General Principles

  • Wrist tendons respond to progressive loading. Complete rest delays healing. Load within pain-free range.
  • Grip modification is the primary intervention. Neutral grip and EZ-bar reduce wrist stress immediately.
  • Wrist wraps support but do not replace strengthening. Use wraps during pressing, but also do wrist rehab.
  • Reduce training volume before eliminating exercises. Often the total volume, not a single exercise, is the problem.
  • Warm up the wrists specifically before training. Wrist circles, light flexion/extension, and grip work prepare the tendons.
  • Ice after training if swollen. 10-15 minutes of ice on the affected tendon post-session can reduce inflammation.

Contraindicated Movements

Straight barbell curls with heavy load (forced supination stresses wrist)Reverse curls during acute phaseWrist curls under heavy load (can aggravate already-inflamed tendons)Behind-the-back barbell wrist curlsAny exercise requiring forced wrist extension under load (e.g., front squat with cross-arm grip)Heavy farmer carries without straps (moderate and severe)

Recommended Exercises

Wrist Flexion with Light Dumbbell (2-5 kg)

3 sets × 15 reps

Progressive loading of the wrist flexor tendons. Begin with very light weight and increase gradually over weeks.

Wrist Extension with Light Dumbbell (1-3 kg)

3 sets × 15 reps

Strengthens wrist extensor tendons. Essential for preventing recurrence. Use slow, controlled movements.

Wrist Pronation/Supination with Hammer or Light Dumbbell

2 sets × 12 reps

Trains rotational wrist strength through full range. Hold a hammer by the handle and rotate forearm.

Grip Squeeze with Soft Ball or Grip Ring

3 sets × reps

Builds grip endurance without high peak forces. Use a compressible ball, not a heavy grip trainer.

Eccentric Wrist Extension (Tyler Twist with FlexBar)

3 sets × 15 reps

Evidence-based protocol for wrist extensor tendinopathy. The FlexBar eccentric protocol has strong research support.

Wrist Circles (Warm-Up)

2 sets × 10 reps

Gentle warm-up for wrist tendons before any gripping or pressing. Perform before every training session.

Return to Full Training

Criteria:

  • Pain-free gripping during daily activities for 2+ weeks
  • Full grip strength restored (can hang from a bar for 30+ seconds without pain)
  • Can perform EZ-bar curls at moderate load without pain
  • Can press with barbell (no wraps) at moderate load without pain
  • No tenderness on palpation of wrist tendons
  • Morning stiffness resolved

Progression:

  1. 1.Week 1-2: Wrist rehab exercises only (flexion, extension, rotation). No heavy gripping. Machines with padded handles for training.
  2. 2.Week 3-4: Reintroduce neutral-grip exercises (hammer curls, cable rows with D-handle). Use straps for pulling.
  3. 3.Week 5-6: Add EZ-bar curls at 50% normal load. Reintroduce pressing with wrist wraps.
  4. 4.Week 7-8: Progress to full curl and pressing load with neutral or EZ-bar grip. Straps for heavy pulling.
  5. 5.Week 9-10: Cautious reintroduction of straight barbell work at reduced load.
  6. 6.Week 11+: Gradual return to full program. Maintain wrist strengthening permanently. Use wraps for heavy pressing as needed.
