Gym injury statistics vary depending on whether they count emergency-department presentations, training exposure or any reported injury. The figures below separate those definitions, populations and periods so U.S. weight-training estimates are not mistaken for the incidence of every gym injury.
Key Gym Injury Statistics
The following highlights summarize the most useful figures across the available U.S. studies and systematic reviews:
- In 1990–2007, 970,801 weight-training injuries were estimated among U.S. emergency-department patients.
- In 1990–2007, 82.3% of U.S. weight-training emergency-department injuries involved males.
- In 1990–2007, 90.4% of U.S. weight-training emergency-department injuries involved free weights.
- In 1990–2007, sprains and strains represented 46.1% of U.S. weight-training emergency-department diagnoses.

U.S. Gym Injury Statistics: Emergency-Department Scale and Long-Term Trends
The strongest national gym-specific estimate in this dataset comes from a NEISS-weighted analysis of U.S. emergency-department visits. It estimated 970,801 weight-training injuries during 1990–2007, but it does not include injuries treated in doctors’ offices, urgent-care settings, at home or without medical attention.
The study’s mean patient age was 27.6 years, with observed ages ranging from 6 to 100 years.
Males accounted for 82.3% of those weight-training emergency-department injuries. That is a share of treated cases, not a participation-adjusted risk comparison between men and women.
For broader context, the CDC estimated 4.3 million nonfatal sports- and recreation-related emergency-department injuries in the United States from July 2000 through June 2001. This broader category represented 16% of all unintentional-injury emergency-department visits, and its overall rate was 15.4 injuries per 1,000 population.
The CDC’s population rates also varied by age and sex, but they should not be read as gym-only rates:
- Among U.S. boys aged 10–14, the sports- and recreation-related injury rate was 75.4 per 1,000 population in July 2000–June 2001, compared with 36.3 per 1,000 among girls.
- Among U.S. people older than 45 in July 2000–June 2001, the rate was 4.3 per 1,000 men and 2.2 per 1,000 women.

Weight-Training Injury Statistics by Sex, Age and Equipment
A separate U.S. analysis focused on weightlifting emergency-department patients aged 14–30 during 2002–2005. It estimated 114,441 male and 22,592 female patients; females comprised 16.5% of analyzed patients.
The approximately 6-to-1 male-to-female ratio is a ratio of emergency-department presentations, not absolute injury risk.
After accidental injuries were removed under the study’s definition, the estimates were 77,145 male and 12,458 female injuries. The sex-specific comparisons were more nuanced than the overall case mix:
- Females had 1.69 times the odds of accidental weightlifting injuries versus males.
- Females had 2.44 times the odds of accidental foot injuries versus males.
- Males had 2.14 times the odds of accidental hand injuries versus females.
Equipment patterns in the longer 1990–2007 analysis show why “gym injury” is not a single mechanism. Free weights were involved in 90.4% of weight-training injuries, while machine-related injuries represented 18.2% of cases among people aged 55 and older, compared with 9.3% among people aged 54 and younger.
| Equipment comparison, U.S. ED cases | Share or outcome | Period and scope |
|---|---|---|
| Free weights involved | 90.4% | Weight-training injuries, 1990–2007 |
| Machine-related injuries, age 55+ | 18.2% | Weight-training cases, 1990–2007 |
| Machine-related injuries, age 54 and younger | 9.3% | Weight-training cases, 1990–2007 |
| Fractures or dislocations, free-weight users | 23.6% | Weight-training cases, 1990–2007 |
| Fractures or dislocations, machine users | 9.7% | Weight-training cases, 1990–2007 |
These are equipment-stratified proportions among emergency-department cases, not exposure-adjusted comparisons or proof that equipment caused the difference.

Gym Injury Diagnoses, Mechanisms and Body Regions
In the 1990–2007 U.S. weight-training analysis, sprains and strains were the leading diagnosis category at 46.1%. Weights dropping on the person accounted for 65.5% of mechanisms, so the case mix includes both exertion-related problems and contact with equipment.
The most common body-region shares in that study were 25.3% for the upper trunk and 19.7% for the lower trunk. Sex and age changed the distribution: upper-trunk injuries were 26.8% of male cases versus 18.4% of female cases, while foot injuries were 22.9% of female cases versus 11.0% of male cases.
Hand injuries were 37.9% among patients aged 12 or younger, compared with 18.2% among older patients.
The CDC’s July 2000–June 2001 sports-and-recreation data provide broader context, not gym-specific estimates. Its diagnosis mix included 29.1% strains and sprains, 20.5% fractures, 20.1% contusions and abrasions, and 13.8% lacerations.
Within that broad CDC category, ankles were the most common named body region at 12.1%, followed by fingers at 9.5% and knees at 8.1%. Because the population includes many sports and recreational activities, these figures should not be merged with weight-training percentages.

Resistance-Training Injury Trends from 2013–2022
A later U.S. NEISS-weighted study examined resistance-training injuries among people aged 14–35 during 2013–2022. It estimated 483,231 male and 125,353 female injuries, with females representing 20.5% of the sample.
The mean ages were 22.76 years for males and 22.93 years for females.
Patients younger than 18 made up 28.7% of male cases and 26.8% of female cases. The recorded setting distribution was incomplete because setting was missing for 41% of cases, so the listed percentages are not exhaustive:
| Recorded setting | Male cases | Female cases | Period and population |
|---|---|---|---|
| Gym or sports facility | 20.9% | 25.8% | U.S. cases aged 14–35, 2013–2022 |
| School | 5.0% | 6.9% | U.S. cases aged 14–35, 2013–2022 |
| Class | 1.3% | 3.4% | U.S. cases aged 14–35, 2013–2022 |
| Home | 2.4% | 2.6% | U.S. cases aged 14–35, 2013–2022 |
Women had an odds ratio of 0.80 for sprains and strains versus men, 1.27 for fractures and 1.52 for contusions and lacerations. These are emergency-department case comparisons, not population-level risk estimates.
Weightlifting and Powerlifting Injury Rates per 1,000 Training Hours
Exposure-based rates answer a different question from national emergency-department counts: how often injuries occur relative to training time. A systematic review of studies available through 2015 found weightlifting incidence of 2.4–3.3 injuries per 1,000 training hours and powerlifting incidence of 1.0–4.4 per 1,000 hours.
A newer systematic review identified through March 2023 reported a much broader overall resistance-training incidence range of 0.21–18.9 injuries per 1,000 hours. It also found prevalence ranging from 10% to 82% across resistance-training studies.
| Measure | Reported result | Scope and limitation |
|---|---|---|
| Weightlifting incidence | 2.4–3.3 per 1,000 hours | Review studies through 2015; mostly low or fair quality |
| Powerlifting incidence | 1.0–4.4 per 1,000 hours | Review studies through 2015; heterogeneous studies |
| Resistance-training incidence | 0.21–18.9 per 1,000 hours | Studies identified through March 2023; varied definitions and exposure methods |
| Resistance-training prevalence | 10%–82% | Studies identified through March 2023; definitions varied |
| Strongman incidence | 5.5 per 1,000 hours | One included study |
| Strongman prevalence | 82% | One included study and its injury definition |
The newer review also summarized prior weight-training literature at approximately 1–2 injuries per athlete per year and approximately 2–4 injuries per 1,000 training hours. Those summaries are approximate cross-study figures, not a single gym-population rate.

Gym Injury Outcomes, Settings and Lower-Extremity Patterns
In the 2013–2022 resistance-training study, emergency-department discharge occurred for 95.7% of male and 96.5% of female cases aged 14–35. Admission occurred for 2.4% of male and 1.7% of female cases, showing that the dataset is dominated by treated-and-released encounters rather than hospital admissions.
The broader CDC sports-and-recreation dataset estimated 350,734 head injuries in July 2000–June 2001, including approximately 199,050 diagnosed brain injuries defined as concussion or internal injury. Hospitalization occurred in 2.3% of those broad sports-and-recreation injury cases; these outcomes are not gym-specific.
A national U.S. analysis of weightlifting-related lower-extremity emergency-department injuries from 2014–2023 estimated 48,344 fractures and 15,397 nerve injuries. Within the weighted lower-extremity subset, contusions and abrasions were 21.0%, fractures were 19.5% and nerve injuries were 5.1%.
Age-specific patterns in that lower-extremity analysis included the following:
- Among U.S. patients younger than 18, toes accounted for 35.2% of lower-extremity injuries and feet accounted for 28.7% during 2014–2023.
- Lower-trunk injuries accounted for 47.0% of young-adult lower-extremity-related cases, 46.7% of middle-aged cases and 33.7% of geriatric cases in the same U.S. analysis.
The lower-extremity findings describe a defined subset of weightlifting-related emergency-department injuries, not all gym injuries. Across the evidence, emergency-department estimates, exposure-based incidence, prevalence and injury outcomes measure different populations and should remain separate.
