The news yesterday intimated that reseachers may someday come up with “exercise in a pill.”
Got me thinking:
I’ve always heard that speed and other stimulants damage the heart.
My question is, if the whole point of exercise is to get the heart pumping at a higher rate and giving it a solid work-out, why do stimulants harm, instead of help the heart?
Why don’t stimulants act as “exercise in a pill?”
