> It requires a very untrained, overweight individual with a relatively modest caloric deficit. It's hard to say because many overweight people already have a significant muscle mass, just those muscles are underused and hidden under the fat. When one starts to exercise and looses some weight their muscles' volume will increase with a better blood flow, and will get the proper shape and also become more prominent with less fat over them, but they'll probably not actually increase the muscle mass itself - it's just that we're now able to see them better.
