So if you took all the fat in your thighs, waist, buttocks and hips and replaced it with muscle it would not only be considerably smaller, but also have much more tone and smoother curves. Because everyone is different it, is your individual body composition that makes up how you look. The truth is women should be concerned about not having enough muscle than too much.
             The amount of time you spend in the gym does significantly matter. Most people are under an assumption that they have learned from early years (mostly 80s), the longer the workout in how, the better the results. This assumption is false. The truth is that too much exercise prevents results. During the 80's professionals were oblivious to this fact as said here, "Not only does that mean he's practically living in the gym, having virtually no time for his wife and kids (or school work), ultimately failing to complete the routine through utter exhaustion (Kennedy 12, 1999). The more reasonable workout time would fall between 45 minutes to an hour, three days a week, and doing a special kind of aerobic training in between for three days. The time when you're not lifting is being used for muscle growth, rest and recuperation of the body.
             One of the most important things in weight lifting is proper form when lifting. It was thought that when you lift a weight, muscle fiber is torn, but the fact is that both lowering and lifting stimulate muscle growth. There are two basic motions to all free weighted exercise. One is called the concentric (lifting) phase; the other, the eccentric (lowering)(Phillips 41, 1999). You need both lifting and lowering the weight to stimulate muscle growth. As you lift and lower, the weight tears muscle fibers during the lowering stage which starts a form of remodeling the muscle. To have this done efficiently, ...
