The effects of exercise on the human body are far more extensive than just increased muscle mass. Replicating all the benefits without any significant side efffects is still far in the future, if it ever comes. However, if the average couch potato wants to become a guinea pig in exchange for the possibility of a healthier body without the work, I say let them.
