Those '50s-era dreams of taking pills to solve all your problems? They're more realistic than you might think. Researchers have created a blueprint of the molecular-level muscle reactions to exercise that should lead to treatments which mimic workouts. Yes, that means that you could eventually take an exercise pill that produces the effects of hitting the gym without all that pesky time and effort. Any pill would be "at least a decade" away, the University of Sydney's Dr. Nolan Hoffman explains, but the scientists are "actively working on" that vision -- it's not just a daydream.
