I'm working on muscles almost 7 hours a week [1 hour a day] and I try to do all the exercises. What surprises me is that I haven't lost any weight. Seems like I've gained weight [I've weighed myself]. Is it because of muscles that I've put on some weight? Also, I've heard that the body is filled with water [especially muscles] when you stop working out. Is that true??? This sounds strange to me.
