- Most gym injuries come from load rising faster than the body can adapt
- Back, shoulder, elbow, knee and wrist problems are the most common
- You can usually keep training with smart modifications while you recover
- A pop with sudden weakness, deformity or a bruise needs prompt assessment
- Chest pain or a sudden severe headache during exercise needs 999
Why gym injuries happen
Strength training has a relatively low injury rate compared with many team sports, and it is one of the best ways to reduce injury risk in everyday life and other sports. When problems do happen, they usually come from a mismatch between load and capacity: the amount, intensity or type of training has risen faster than your muscles, tendons, joints or bones can adapt to it.
- A sudden jump in volume or intensity, such as a new programme or a challenge month
- Chasing a personal best on a tired day
- Technique breaking down under fatigue, late in a session or a conditioning workout
- Poor sleep, high stress and not eating enough, which lower recovery
- Returning after a break at the same weights as before
- Lots of the same movement pattern in a short period, such as high-rep pressing or jumping
It is rarely one bad rep out of nowhere. Even when something goes twang on a deadlift, there has often been a build-up of fatigue or a niggle that was ignored.
The most common gym injuries
- Lower back tweaks, often during deadlifts, squats or kettlebell swings: see our guide to lower back pain.
- Shoulder pain with pressing or overhead work, often rotator cuff related: see shoulder impingement.
- Elbow pain from pulling and gripping: tennis elbow and golfer's elbow.
- Wrist pain from push-ups, front racks and burpees.
- Knee pain from squats, lunges, jumps and running, such as runner's knee or patellar tendinopathy.
- Hamstring and calf strains from sprints, sled work and explosive movements.
- Achilles pain from running and jumping volume.
Most of these are very treatable, and most allow you to keep training in some form while they settle.
Acute injuries, such as a sudden back spasm or a tweaked hamstring, tend to settle faster than problems that have crept up over months, such as tendon pain. The latter usually need a longer, more structured plan, but they respond just as well.
Train around it, not through it
Complete rest is rarely the best option for gym injuries. It often leads to lost fitness and strength, and the problem can return as soon as you go back. Pushing through sharp or worsening pain is not the answer either. The middle ground is training around the injury: keeping everything you can, and modifying what aggravates it.
- Sore back: swap heavy barbell deadlifts for lighter hinges, reduce range, or use a trap bar, while keeping upper-body and conditioning work.
- Sore shoulder: swap barbell overhead pressing for a landmine press or neutral-grip dumbbells, reduce range and add rotator cuff work.
- Sore elbow: use straps and neutral grips for pulling and reduce hanging volume.
- Sore knee: reduce squat depth or load, swap lunges for step-ups or box squats, and use the bike instead of running.
- Sore wrist: use dumbbells or push-up handles to keep the wrist straight.
Our guide to training with a niggle has more on judging how much to modify. A useful guide is that mild discomfort, up to about 3 or 4 out of 10, that settles within 24 hours is usually acceptable.
What a physio does for gym injuries
A physio who understands training will assess the injured area, look at your programme and technique, and work out what has driven the problem. They will then help you modify training, build a rehab plan that fits around your sessions, and progress you back to your normal lifts, often stronger than before.
That might include manual therapy to ease pain early on, specific strengthening for the injured area, technique changes, and a plan for reintroducing heavy or explosive work. Our guide to returning to lifting covers the rebuild once you are close to normal.
A good gym-focused physio will also help you avoid the next one. That might mean looking at how your week is structured, how often you train to failure, how you manage deloads, and whether any lifts need more technique work before they get heavy again.
Stopping it happening again
Most gym injuries are preventable with sensible programming: gradual increases in load, planned deloads, a proper warm-up, enough sleep and food, and paying attention to niggles before they become injuries. Our guide to injury prevention for lifters covers this in detail.
Coached classes help too. In a well-run strength or conditioning class, a coach can spot technique fading, suggest scaled options and stop you chasing numbers on a bad day. That extra pair of eyes is one of the underrated benefits of training with a coach.
When to stop and get checked
Some gym injuries need prompt medical assessment rather than training around. If you train at Lycan Strength, the on-site physio can assess most gym injuries, with 20% off for members; you can book a physio appointment online. For the following, get help straight away:
- Call 999 for chest pain, tightness or breathlessness during or after exercise, or a sudden, severe headache while lifting.
- Call 999 or go to A&E for numbness around the genitals or buttocks, new bladder or bowel problems, or weakness in both legs.
- Go to A&E for a deformity, a suspected dislocation or being unable to bear weight.
- See a GP, physio or urgent treatment centre within days for a pop with sudden weakness and bruising, such as in the chest during bench press, the front of the elbow during a heavy pull, or the back of the ankle.
- Call NHS 111 or see a GP urgently for a hot, red, swollen joint or a swollen, painful calf.
Questions
Should I stop going to the gym with an injury?
Usually not completely. Most gym injuries allow you to keep training with modifications, which helps you maintain fitness and recover faster.
What is the most common gym injury?
Lower back and shoulder problems are among the most common, followed by elbow, knee and wrist pain. Most are overload problems that respond well to rehab.
How do I know if a gym injury is serious?
A pop with sudden weakness, deformity, heavy bruising, inability to bear weight, or numbness and bladder or bowel changes need prompt medical attention.
Can a physio help with lifting technique?
A physio who understands training can look at how you move and suggest changes that reduce strain on the injured area while you rebuild.
