Gym & Weightlifting InjuriesBack, Shoulder & Knee

Back pain from deadlifts and squats, shoulder pain from pressing, knee pain from squatting, and sciatica from heavy loading. Many lifting injuries have mechanical causes and mechanical solutions.

The short version

If you're dealing with lower back pain from deadlifts or squats, shoulder pain from pressing, or knee pain that flares every time you load up the bar, the underlying cause is almost always mechanical. Many persistent gym injuries reflect a mobility restriction, strength imbalance, or technique issue that concentrates load where it shouldn't be. The goal is to identify the mechanical cause and fix it, not to remove you from the gym.

Why most lifting injuries are fixable

The goal is to keep you training while the underlying restriction is addressed. If you've already dropped the weight and adjusted your form and it's still not clearing up, that's a sign the restriction needs to be addressed directly, not just through coaching adjustments. Technique can only change so much when the underlying mobility limitation is unaddressed.

Gym injuries are overwhelmingly mechanical overuse injuries, not acute structural failures. Most persistent gym injuries (back pain from deadlifts, shoulder pain from pressing, knee pain from squatting) reflect a mobility restriction, strength imbalance, or technique issue that concentrates load on structures that weren't the intended primary movers. The exception is acute muscle tears or fractures from maximal effort lifts, which are rare in recreational gym-goers.

A key distinction: mobility restrictions that drive gym injuries are addressable. Hip mobility limiting squat depth, thoracic extension limiting overhead press mechanics, wrist mobility limiting front rack position. These can be improved through targeted joint mobilization and soft tissue work combined with specific exercise. The goal is not to modify the exercise indefinitely, but to address the underlying mechanical cause of the injury.

Common presentations

  • Lumbar pain from deadlifts and squats: most commonly from lumbar flexion under load driven by restricted hip mobility or limited thoracic extension. The question isn't just "does the back round" but why, and whether that pattern is concentrating load on irritable structures. Often improved by addressing hip mobility and thoracic extension alongside technique adjustments.
  • Shoulder impingement and rotator cuff tendinopathy from pressing: bench press, overhead press, and dips are common drivers. Often related to restricted thoracic extension (limits the shoulder from getting overhead efficiently) and glenohumeral internal rotation deficit. Restoring thoracic mobility and shoulder rotation capacity often changes how pressing feels.
  • Patellar tendinopathy from squatting: pain at the bottom of the kneecap from tendon overload. Common with high-volume squatting, jumping, or leg press. Responds to progressive loading rehabilitation, not prolonged rest.
  • Sciatica from heavy loading: disc irritation from repeated heavy spinal loading, particularly with flexion under load. Leg symptoms alongside back pain during or after heavy lifting. Usually manageable without imaging before resuming modified training, but clinical assessment determines whether there are signs that change that picture.
  • Wrist pain from front rack or overhead positions: limited wrist extension and forearm rotation affects clean and jerk, front squat, and overhead squat mechanics. Usually addressable with wrist joint mobilization and specific mobility work.

What helps

Complete rest from training is rarely necessary. The goal is to identify which movements are provocative, modify them appropriately during recovery, and keep you training at a level that doesn't aggravate the injury while the underlying issue is addressed. I work with recreational and competitive lifters who need to stay on a programme, whether that's working around a peaking cycle or simply keeping training continuity, and the assessment is designed around managing load rather than replacing it with rest. For most gym injuries, this means technique modification, load reduction on specific exercises, or temporary substitution, not stopping training entirely.

Manual therapy addresses the mobility restrictions directly. Hip mobility limiting squat depth, thoracic extension restricting the overhead press, glenohumeral capsular restriction contributing to shoulder loading: these respond well to specific joint mobilization and soft tissue work. Combined with a targeted exercise program and technique adjustments, many gym injuries respond well to conservative care.

Training load and progressive overload

In most persistent gym injuries, the driving factor is cumulative load relative to tissue capacity rather than technique error alone. The two often interact. The body adapts to training stress over time, but adaptation requires adequate recovery. When training volume or intensity increases faster than tissues can adapt, something gets overloaded. The tendons, joints, and discs that absorb the most stress in a given movement pattern are typically the ones that react first.

If you've been dealing with a persistent gym injury that hasn't responded to rest, the missing element is often a progressive loading programme, not more rest.

On shoulder assessment for pressing injuries

Acute shoulder pain during a heavy set followed by significant weakness (inability to raise the arm against resistance) suggests a meaningful structural injury and warrants imaging before continuing to train. More commonly, gym shoulder injuries are impingement or tendinopathy: painful but not structurally ruptured. Note that partial-thickness tears and labral injuries may not cause complete loss of arm elevation but can still warrant imaging. Clinical assessment with multiple tests can meaningfully guide diagnosis, though imaging confirms where clinical suspicion warrants it. If I think imaging is warranted, I'll tell you exactly what to request and from whom.

The goal is to identify what's provocative, modify accordingly, and keep you lifting while the underlying issue is addressed. If you'd like to talk through your situation before booking, get in touch.

When to seek care promptly

See a doctor if you have:

  • Acute severe back pain during a lift with leg weakness, numbness, or any loss of bladder or bowel control
  • Shoulder weakness that appeared acutely during a heavy set
  • A pop or snap in a muscle during maximal effort, followed by significant weakness
  • Back or leg symptoms that are worsening rather than improving with load modification
  • Groin or hip pain with significant restriction or pain at end-range in multiple hip movements
  • Chest tightness, jaw pain, or arm pain during or immediately after heavy lifting

Most gym injuries are appropriate for conservative management with appropriate load modification. Structural injuries and progressive neurological symptoms need medical assessment.

Common questions

Rarely. The goal is to identify which movements are provocative, modify them appropriately, and keep you training at a level that doesn't aggravate the injury while the underlying issue is addressed. For most gym injuries, this means technique modification, load reduction on specific exercises, or temporary substitution, not complete rest from training. I'll give you specific guidance on what's safe and what to avoid at your current stage.

Tightness or discomfort running down the back of the thigh after heavy loading is fairly common and is often referred pain from the lumbar spine rather than nerve root compression or irritation. It warrants proper assessment. The clinical picture determines how urgently. The key questions are whether the symptom is getting worse over time, whether you're noticing any weakness or numbness alongside it, and whether it's present at rest or only after loading. If the symptoms are progressing or you have any neurological signs (weakness, numbness, pins and needles), get it assessed before continuing heavy training. If it's only present after sessions and clears within a day or two, that's a different picture than tightness that builds progressively or doesn't clear with rest. The former is lower urgency; the latter warrants prompt assessment.

Butt wink (posterior pelvic tilt at the bottom of the squat) can contribute to lumbar pain if it's significant, but its impact is often overstated. The primary questions are: what's causing the loss of lumbar position (hip mobility restriction? ankle dorsiflexion restriction? femoral anatomy?), and is the movement pattern placing load on irritable structures? I'll assess your squat mechanics as part of the consultation if that's the relevant movement, and give you both clinical context and practical guidance.

Yes, restricted thoracic extension and glenohumeral mobility are common reasons why the overhead press feels unstable or causes shoulder pain. Restoring thoracic mobility and shoulder rotation capacity often changes what the press feels like, and can also improve front rack position for the clean and jerk. I'll assess what's limiting your position and work on it directly.

Acute pain during a heavy set followed by significant weakness (can't raise the arm against resistance) suggests a meaningful structural injury and warrants imaging. More commonly, gym shoulder injuries are impingement or tendinopathy, painful but not structurally ruptured. Note that partial-thickness tears and labral injuries may not present with complete arm elevation loss but can still warrant imaging. Clinical assessment with multiple tests can meaningfully guide diagnosis, though imaging confirms where clinical suspicion warrants it. If I think imaging is warranted, I'll tell you exactly what to request and from whom.

These timeframes are for mild-to-moderate presentations; complex or longstanding injuries typically take longer. For most gym injuries in that range, in my experience meaningful improvement within 6-10 sessions is realistic with appropriate exercise modification. Return to full unrestricted training depends on the specific injury: lumbar disc irritation from lifting typically needs 8-12 weeks before heavy loading is appropriate again; shoulder tendinopathy from pressing can take 8-12 sessions with gradual load reintroduction. Most people can return to modified training within the first 2-3 sessions while the heavier loading recovers. I'll give you specific milestones rather than just a session number.
