Back-Cycling - Cutting back on either number of sets, repetitions or amount of weight used during an exercise session.
Body Composition - For bodybuilders, the amount they weigh is not important, but their body composition is. For example, a person may be 5'10 and 300 lbs, but if they are 40% body fat, these stats are not as impressive for the judging booth. Bodybuilders worry less about their weight and more about their body composition, which is defined as the ration between lean body mass (muscle, bone, and connective tissue), body fat, and water. Never be afraid to eat, though. One of the best ways to gain lean muscle mass is to eat a lot and let your body fat levels rise in order to do so. This said, don't let your bulking stage get out of control. It is essential that you keep your total body fat percentage close to what you would like it to be after your cutting stage. It is very difficult, if not impossible to gain muscle mass while simultaneously cutting body fat. Although they have said this is possible with the use of human growth hormone (HGH), it is really not essential. Be patient, muscles come in time.
Body composition - The percentage of your body weight composed of fat compared to fat-free mass.
