Can push-ups predict heart health? What the research says

Possibly, as one signal among many. In a 10-year study of 1,104 active male firefighters (Yang et al., JAMA Network Open, 2019), men who could do more than 40 push-ups had a much lower rate of cardiovascular events than men who managed fewer than 10 (incidence rate ratio 0.04, 95% CI 0.01 to 0.36), after adjusting for age and BMI. It is an association in one fairly narrow group with only 37 events, not proof that push-ups protect your heart. Broader evidence points the same way: a meta-analysis of 16 cohort studies linked muscle-strengthening activity with a 10-17% lower risk of cardiovascular disease and death from any cause. The useful takeaway is to train strength regularly and track a fair push-up count over time.

"If you can do 40 push-ups, your heart is fine" is a headline that has done the rounds since 2019. There is a real study behind it, and it is worth knowing what it found, who was in it, and what it cannot tell you. This guide covers that study, the wider evidence on strength training and health, and how to test and improve your own push-up count fairly.

The 40 push-up study

Yang and colleagues at the Harvard T.H. Chan School of Public Health looked back at the records of male firefighters examined at one outpatient clinic in Indiana (JAMA Network Open, 2019). Push-up capacity was tested at baseline, participants were put into 5 groups by how many push-ups they completed, and cardiovascular outcomes were followed for 10 years.

The authors found a significant negative association: the more push-ups, the fewer cardiovascular events. They concluded that push-up capacity may be a simple, no-cost measure of functional status, and that larger studies in more diverse groups are needed.

What that study can't tell you

The result is striking, but it has limits that the headlines usually drop:

• It shows an association, not cause and effect. Men who can do 40 push-ups are probably fitter, more active and healthier in other ways. Push-ups may be a marker of all of that rather than the reason for it.
• The group was narrow. Active, working male firefighters. No women, and few older or sedentary adults.
• There were only 37 events. That is why the confidence interval is so wide (0.01 to 0.36). The direction is clear; the exact size of the effect is not.
• 40 is a group boundary, not a medical cutoff. Doing 39 does not put you at risk, and doing 41 does not clear you.

So treat a push-up count as a rough fitness signal you can track, not a heart test.

The bigger picture: strength training and health

A broader body of evidence supports the general idea. Momma and colleagues pooled 16 prospective cohort studies of adults without severe health conditions (British Journal of Sports Medicine, 2022). Independent of aerobic activity, muscle-strengthening activities were associated with:

• A 10-17% lower risk of all-cause mortality, cardiovascular disease, total cancer, diabetes and lung cancer.
• The largest risk reduction (about 10-20%) at roughly 30-60 minutes a week for all-cause mortality, cardiovascular disease and total cancer. Beyond that the curve was J-shaped, so the authors call the effect of much higher volumes unclear.
• A lower risk still when muscle-strengthening and aerobic activity were combined.

These are observational findings too, but they come from many cohorts rather than one. They match public guidance: the Physical Activity Guidelines for Americans advise muscle-strengthening activity on 2 or more days a week (health.gov), and the 2020 WHO guidelines recommend it for all age groups (Bull et al., British Journal of Sports Medicine, 2020).

Are push-ups enough strength training for the upper body?

For the chest, shoulders and triceps, they can be, if you keep them hard. Calatayud and colleagues had 30 university students with advanced training experience do either a 6-rep-max bench press or a 6-rep-max elastic-band push-up for 5 weeks (Journal of Strength and Conditioning Research, 2015). Muscle activity was similar for both exercises at baseline, and both groups improved their 1-rep and 6-rep max by similar amounts, while a control group did not change.

The key detail is that the push-ups were loaded with a band to match a heavy bench press. Once plain push-ups get easy, the stimulus drops. You keep progress going by making them harder: slower lowering, a pause at the bottom, feet raised, a band, or a weighted vest. Push-ups do nothing for your legs or back, so they are one part of a routine, not the whole thing.

How to test your push-ups fairly

A count only means something if it is done the same way each time:

1. Use one standard. Hands about shoulder-width, body straight from head to heels, lower until the elbows reach about 90 degrees, lock out at the top.
2. Count only full reps. Reps get shallower as you tire, and you cannot see your own depth. Filming the set or using a counter that tracks range of motion keeps the number honest.
3. Keep the conditions the same. Same time of day, same warm-up, rested, no pauses on the floor.
4. Compare yourself with yourself. Age and sex norms are rough (see the push-up test by age). The more useful number is your own count six weeks from now.
5. Retest every few weeks, not every day. In between, train with sets that stop a rep or two short of failure (see how close to failure should you train).

If you have chest pain, dizziness or unusual breathlessness during exercise, stop and see a doctor. A push-up test is not a substitute for a medical check.

Counting is where most push-up tests go wrong

The research above depends on clean counts done to a standard. At home, that is the hard part: a tired set turns into half reps, and the number in your head creeps up.

Disclosure: we make RepSquad. RepSquad counts reps with the iPhone camera, shows a range-of-motion bar and gives A/B/C form feedback on-device across 11 exercises including push-ups, squats, lunges and pull-ups. It counts what the camera sees; it does not measure heart health or tell you anything medical. Download is free; some features need an in-app purchase (App Store).
