In a Nutshell
- Men who completed 40 or more push-ups had a 96% lower rate of cardiovascular events over 10 years compared with men who could only manage fewer than 10.
- Harvard-affiliated researchers tracked more than 1,100 male firefighters and found that push-up capacity at the start of the study was a strong predictor of who would later develop coronary artery disease, heart failure, or suffer sudden cardiac death.
- In this cohort, push-up capacity was more strongly associated with future cardiovascular risk than estimated fitness from submaximal treadmill testing, which can over- or underestimate true fitness levels.
- Because the study involved only active male firefighters, the findings may not apply to women, older adults, or sedentary populations, and the authors call for broader research before push-up testing is adopted as a universal screening tool.
Men who can crank out 40 or more push-ups have a 96% lower rate of cardiovascular events over a decade compared with men who tap out at fewer than 10. That’s not a misprint. It comes from a rigorous, 10-year study tracking more than 1,100 middle-aged male firefighters, a physically demanding workforce with well-documented long-term cardiac risks.
Harvard-affiliated researchers published the findings in a 2019 JAMA Network Open paper after following male career firefighters from Indiana for up to a decade. Push-up capacity, measured at the start of the study, turned out to be one of the sharpest predictors of who would go on to develop coronary artery disease, heart failure, or suffer sudden cardiac death. Men who cleared the 40-push-up threshold had very few recorded cardiac events over the study period.
Even more notable was what push-ups managed to outdo. In this cohort, push-up capacity was more strongly associated with future cardiovascular risk than estimated fitness from submaximal treadmill testing. The authors note that submaximal stress tests can over- or underestimate true fitness because they rely on extrapolation rather than direct measurement. For a country where cardiac disease remains the leading cause of death, that’s a finding worth paying attention to.

What the 40-Push-Up Study Actually Measured
Researchers drew their group from male career firefighters at 10 Indiana fire departments, all of whom went through periodic medical checkups at a single outpatient clinic between 2000 and 2007. Of 1,562 eligible participants, 1,104 had complete push-up data and were included in the final analysis. Their average age at the start was roughly 40, and they were followed for up to 10 years.
Push-up capacity was measured under standardized conditions. Each man performed push-ups in time with a metronome set at 80 beats per minute, continuing until he completed 80 reps, missed three or more beats, or stopped due to exhaustion or symptoms such as dizziness or chest pain. Participants were sorted into five tiers: fewer than 10, 11 to 20, 21 to 30, 31 to 40, and 41 or more.
Over the follow-up period, 37 cardiovascular events occurred across the group. When researchers mapped those events back to baseline push-up performance, a clear gradient emerged. Men who could manage 21 to 30 push-ups had a 75% lower rate of cardiac events than those stuck below 10. Men clearing 40 had that 96% lower rate. Even accounting for age and body mass index, the association between push-up capacity and reduced cardiac risk held up.
Why Push-Ups May Signal Heart Health
Push-up capacity reflects more than upper-body strength. It captures whole-body muscular fitness and the cardiovascular system’s ability to sustain effort, both of which are closely linked to heart health. Men who performed more push-ups in this study also tended to have lower BMIs, better blood pressure, lower triglyceride levels, and lower smoking rates, all recognized cardiovascular risk markers. The researchers note that some of the risk reduction seen at higher push-up levels may be explained by those underlying differences, rather than push-ups themselves acting as a direct protective mechanism.
That caveat matters: the study shows an association, not a cause-and-effect relationship. The authors caution that the results do not prove push-up capacity is an independent clinical predictor of CVD risk. But as a quick, objective indicator of a man’s overall physical condition, the number is telling.
Still, the practical case for adding push-ups to the clinical toolkit is difficult to ignore. As the authors write, the exercise “requires no special equipment, is low cost or no cost, can easily be performed in almost any setting within 2 minutes, and provides an objective estimate of functional status.” Most primary care offices don’t own treadmills or employ exercise physiologists. A push-up test requires neither.
Who This Research Does and Doesn’t Apply To
Every participant in this study was an active, working male firefighter, a group that is already more physically fit than the general population. The cohort was also drawn entirely from Indiana and was predominantly White. None of that translates smoothly to women, older adults, sedentary office workers, or people with existing health conditions. The authors explicitly call for follow-up studies in broader, more diverse populations before push-up testing gets adopted as a universal screening tool.
There’s also a statistical wrinkle: the analyses weren’t adjusted for multiple comparisons, which means some of the significant associations could be products of chance rather than real patterns. And because the fitness evaluation was voluntary, about a quarter of the original group never completed the push-up test, reducing the study’s overall statistical power.
A man who maxes out at 40 push-ups shouldn’t take that as a clean bill of cardiac health. But a man who struggles to reach 10 might reasonably take it as a prompt to have a longer conversation with his doctor. For clinics and workplaces that lack the equipment for formal fitness testing, a two-minute push-up count could be exactly the kind of low-barrier flag that gets someone into care before a cardiac event forces the issue.

Paper Notes
Limitations
The study cohort consisted entirely of active male firefighters from Indiana fire departments, making it difficult to generalize the findings to women, older adults, sedentary populations, or people in other occupations. Because participation in the fitness evaluation was voluntary, push-up data were missing for roughly one-quarter of the original 1,562-participant pool, which reduced statistical power. The authors also note that the analyses were not adjusted for multiple comparisons, meaning some statistically significant associations could be attributable to chance. Additionally, the study establishes an association between push-up capacity and cardiovascular events but does not support push-up capacity as an independent predictor of CVD risk in the clinical sense.

So 37 of 1100 cannot do 40 pushups and are prone to heart disease, which is roughly 3.5% of the group affected. I think the study is flawed as firefighters tend to have a higher rate of CVD compared to the average person.
The study doesn’t take into account that someone may do other forms of exercise but cannot do 40 pushups due to an AC or other problem. It’s similar to the BMI…which doesn’t account for muscle mass versus fat mass. With BMI, a male who is 6 feet tall, 200 lbs and 10% bodyfat is put in the same category as a male of same height and weight, with 30% bodyfat.
Based on the results, I’ve been trying to get it. I am now on 35 that is near to 40. I’ll got it in the near future.
So wait, do these studies say exercise and physical fitness enhances health?
Wow, what a stunning revelation! I have been waiting for these results, and next January 1st, I might just start exercising.
best comment so far!!!
