Common Gym Injuries
As you get older, you realise, that one injury can end your training for months. In addition, injuries acquired after the age of 40, tend to stay in some format and remain as a permanent pain the arse, or shoulder etc.
The peer‑reviewed data on gym injuries is out there. I’ve put it into tables and graphs to show the most common sites of injury:
The Gym Injury League Table
Rank body parts by how often they get hurt in the gym and three names sit at the top of every study. Nobody swaps places.
A Saudi cross‑sectional study of 1,012 gym‑goers gave the shoulder 25.2% of all injuries. The knee took 20.2%. The lower back took 17.7% (Hetaimish et al., 2024). Flip to a Dutch survey of 494 injured fitness participants. Same podium – shoulder, leg, knee (Kemler et al., 2022). Now look at a 25‑study systematic review of CrossFit covering 12,079 practitioners. Same three again: shoulder 26%, spine 24%, knee 18% (Rodríguez et al., 2022).
Different sport. Different country. Same top 3 sites of injury (on the body).
Here’s how the whole league table looks when you smash the studies together:
| Rank | Body part | Share of all gym injuries |
|---|---|---|
| 1 | Shoulder | 25 – 26% |
| 2 | Lower back / spine | 17 – 24% |
| 3 | Knee | 18 – 20% |
| 4 | Elbow / wrist | 7 – 10% |
| 5 | Hand / fingers | 5 – 15% |
| 6 | Hip / hamstring | 3 – 7% |
The shoulder is the delicate and injury-prone area. Doesn’t matter what you do. Lift, box, do CrossFit -the shoulder is first injury on the physio’s table. There’s a reason and it’s boring: it has the widest range of motion in the human body, held together mostly by soft tissue. Load it hard, load it often, and it complains.
The Hourly Wage of Pain
Counting total injuries is cute. Per‑hour rate is honest. A bodybuilder training six hours a week is not the same beast as a strongman training fifteen. Sports scientists get around this by counting injuries per 1,000 hours of training.
Here’s the leaderboard, drawn from the Keogh & Winwood (2017) systematic review and the Rodríguez CrossFit review:
| Activity | Injuries per 1,000 hours |
|---|---|
| Musculação | 0.24 – 1 |
| Powerlifting | 1 – 4.4 |
| Olympic weightlifting | 2.4 – 3.3 |
| CrossFit | 2 – 5 |
| Strongman | 4.5 – 6.1 |
| Highland Games | 7.5 |
For context: football sits at 12 – 35 injuries per 1,000 hours. Rugby is worse. So the gym is not a dangerous place. It just feels dangerous because injuries happen slowly, on your own, with heavy things nearby.
Bodybuilding topping the safety chart will surprise a few people. It shouldn’t. Isolation moves, machines, controlled tempo and never really testing a true max lift equals low injury rate. Trouble starts when you chase a PB.
Who’s Getting Hurt
The US emergency department data covers 970,801 weight‑training injuries between 1990 and 2007 (Kerr et al., 2010). Mean age 27.6. Men were 82.3% of cases. The upper trunk led at 25.3%, lower trunk second at 19.7%. That’s a lot of tweaked backs.
Gender plays a role. Men rack up more sprains and strains -the classic “I loaded too much” injury. Women pick up more accidental injuries -dropped plates, slips, catches. Men are roughly six times more likely to appear in the injury stats, which mostly reflects who’s in the weight room rather than who’s less coordinated (Quatman et al., 2009).
Novices get hurt more per hour than experienced lifters. Competitors get hurt more than recreational lifters. The CrossFit review found a 40% injury rate in competitive practitioners versus 19.05% in recreational ones. Over double (Rodríguez et al., 2022).
The Big Three Lifts – What Actually Goes Wrong
Supino is where the single biggest chunk of gym injuries happens.
In the Dutch data, 11.8% of all injuries came during a bench press (Kemler et al., 2022). Pec tears, shoulder pain and elbow strain top the list. A 2024 narrative review pinned most of the risk on muscular fatigue plus reps‑to‑failure plus grip‑width choices that stick the shoulder in an unstable position (Motlagh & Lipps, 2024).
Squat was behind 9.6% of injuries in the same Dutch data. Lower back and knees mostly. A 2025 systematic review of squat biomechanics showed that as intensity rises past 85% of 1RM, joint variability rises with it – the lifter’s technique starts wobbling in ways that predict injury (Bakhshinejad et al., 2025).
Deadlift doesn’t show up nearly as often as you’d think. But when it does, it’s usually the lower back or a hamstring tear. And the mechanism is nearly always the same: rounded lower back at max effort.
The Adjustments That Actually Cut Your Risk
The same studies that count injuries list the tweaks that stop them. This isn’t guesswork.
1. Warm up properly. Not treadmill‑and‑hope. A structured warm‑up cut injury rate by 36% across 15 pooled studies (Ding et al., 2022). Five to ten minutes of dynamic mobility, activation drills, and a couple of light‑load sets of the actual lift you’re about to do.
2. Cap your fatigue. Reps to failure is a shoulder injury waiting to happen. Velocity‑based training, RPE, or leaving 2 – 3 reps in reserve give almost identical strength gains without the injury cost (Motlagh & Lipps, 2024). Train hard. Don’t train stupid.
3. Progress load gradually. Big weekly jumps raise your risk. There’s no perfect number – the classic “10% a week” rule was never actually tested in a proper trial -but the direction is obvious. Add small, add often. Not big and rare.
4. Get supervised early on. Lack of coach supervision was a repeatable predictor of CrossFit injuries (Rodríguez et al., 2022). It’s the same for general gym use. Seventy‑three percent of the Dutch fitness injuries happened during unsupervised training (Kemler et al., 2022). A few coached sessions at the start pay for themselves for a decade.
5. Don’t train hurt. Previous injury is the single strongest predictor of future injury in almost every gym‑injury paper on record. If it hurts, drop the load. Or drop the lift. Until it doesn’t.
6. Session length matters. The Saudi data showed sessions over two hours had higher rates of strains, dislocations and subluxations. Sessions of 1 – 2 hours pumped up tendinopathy rates. Under an hour and you mostly got cramps and bruises (Hetaimish et al., 2024). If you’re in the gym over two hours you’re either an elite athlete or you’re wasting time and stacking injury risk.
7. Prehab the shoulder. Every study points at the same joint. Do one bit of prehab – banded external rotations and face pulls, two or three times a week. Five minutes. It targets the joint that ends more training blocks than anything else.
Conclusão
The gym is not dangerous. It’s safer per hour than football, rugby, running or cycling. But the injuries you do pick up cluster in a very predictable pattern – shoulder, lower back, knee – and the causes are just as predictable. Too much load. Too fast. Too much fatigue. Too little warm‑up. Nobody watching.
Fix those five things and you’ll train for decades without a serious problem. Ignore them and you’ll be reading this again after your first pec tear. Your call.
