Why is exercise good for your heart while stimulants like coffee are bad for your heart?

In brief: Physiology

Aerobic exercise beneficially impacts the cardiovascular tone of the body (lower bp, lower heart rate, increased cardiac reserve), as well as helps with weight and blood sugar management.
Stimulants simply ramp up the heart rate and blood pressure as a direct effect of the chemicals (usually caffeine, but some analogues to Adrenalin are in them, too), without the physiologic benefits.

I agree with Dr. Loh's answer but, just to clarify, while stimulants like amphetamines are harmful, studies have failed to show that coffee is generally harmful. It is believed, in fact, to have anti-oxidants that are beneficial!
