How to live longer: Push-ups could lower your risk of heart disease and boost longevity

According to Dr Phillips, an average 65-year-old man should be able to do six to 16 push-ups.

But he added: “Don’t focus on a certain number, but rather on what you can do right now and work from there.”

The NHS advises adults do some type of physical activity every day, and that any type of activity is good for you – the more you do the better.

It states adults should do strengthening activities that work all the major muscles (legs, hips, back, abdomen, chest, shoulders and arms) on at least two days a week.
