How does grip strength compare to push-up capacity as a health marker?

Both grip strength and push-up capacity predict cardiovascular events, but they capture different aspects of musculoskeletal health: grip strength reflects systemic muscle quality, neuromuscular function, and is strongly correlated with lower-extremity strength and overall lean mass; push-up capacity reflects upper body strength endurance, core stability, and has been validated specifically for cardiovascular event prediction in active middle-aged men in the Harvard push-up study (Yang et al., JAMA Network Open, 2019).

The Yang et al. 2019 study (10-year follow-up of 1,562 male firefighters) found men who could do more than 40 push-ups had 96% lower risk of cardiovascular events compared to those who could do fewer than 10, a more powerful predictor than treadmill VO2max test results in that population. This is partly due to confounding (men who can do 40 push-ups are generally healthier overall), but push-up capacity is a valid, free-to-test functional cardiovascular risk marker that any man can assess without equipment.

Honesty Scale: Grip strength as mortality predictor, Solid (1) from large meta-analyses. Push-up capacity for cardiovascular events, Promising (2) from one large study pending replication.

What to do: Test and track both annually. If push-up maximum is below 15 for a man under 50, this represents both a functional fitness concern and a reasonable cardiovascular risk signal that warrants increasing upper body and core training.
