Suppose one day I walk up to you and offer you a single pill that would make it as if you were exercising perfectly every day, without the actual need for exercise. Sit on your butt and play video games all day or go outside and run a mile for the sheer joy of it, no difference; your body in both cases would respond as if you were exercising well. No ifs, ands, or buts, no tricks, no gotchas, except I will point out this isn't a "perfect health" pill; I'm not guaranteeing you won't get cancer or a bad cold or a pulled muscle if you exceed your limits, just guaranteeing that you will receive all the benefits of exercising, including toned muscles, strength, etc..
Would you take it?
