If Exercise Were A Pill

There's a saying you hear, "If exercise were a pill, then everyone would take it."

The idea is it's so good for you...
if only it weren't such a pain to do.

Well, someone claims to be getting closer:

'Ali Tavassoli, a professor of chemical biology, and Felino Cagampang, an associate professor in integrative physiology, reported that they had synthesized a molecule that acts as an "exercise mimic" by tricking cells into thinking they have run out of energy.'

But what if the pill's too costly,
and leaves you feeling exhaustly?
