Muscle growth is more than just moving heavy weights—it's a complex biological response. In this video, we explain how resistance training creates micro-tears in your muscle fibers, triggering a ...

Why some of us have sculpted, toned and visible muscles and some of us carry a little more flab depends on a lot of factors. Part of it is how and how much you work out, explains Todd Schroeder, ...
