One can exercise too much

According to experts, one can overdo it when it comes to exercise. Overzealous exercisers can run their way into stress fractures, insomina, and comrpomised immune systems. Every individual has a different threshold, however, one hour daily seems to be the maximum. More than 12 hours of exercise a wekk does not allow the body to bounce back well.

Of special concern are middle-age men who get back into exercise after years of inactivity and are at risk for heart attacks.
