no

The claim that a doctor advises there's no point to exercising because you'll use up your fixed number of heartbeats faster has been circulating online since at least 2009.

Research has instead shown that the heart does not stop beating because it has reached its limit of heartbeats; rather, it stops beating because it weakens. 

Although exercise does lessen the body's glycogen stores, that energy is restored through proper intake of food and water.
