Men who can pump out 40 pushups in one minute reduce their risk of cardiovascular disease by 96 percent, says a study from the Department of Environmental Health at Harvard T.H. Chan School of Public Health. Pushups are the ultimate adapter exercise. They can be done anywhere. They recruit more than half the muscles in the upper body, as well as much of the core. And they’re safe to do. Turns out, they’re also a measurement of overall health. Try this workout daily as you work to attain better cardiovascular health.
