If you put exercise into a pill, it would probably be better than anything a doctor could give you to improve heart health, says Prof Dan Augustine.
If you have done no exercise in the past, you need to build it up, says Augustine. Older people have more cardiac problems when they are exercising.
Generally speaking, you can't do too much exercise. If you're doing really intense stuff like ultramarathons, says Augustine, there is some evidence that you can cause some heart damage.
