Circuit Training Circuit Training consists of a series of resistance exercises performed one after another with little rest between exercises. Its major advantage is the ability to perform a lot of different exercises in a short period of time. Circuit training can improve both strength and muscular endurance, however strength development is generally greater when longer rest periods are used. Gaining Weight Through Resistance Training Many recreational and competitive athletes use weight training to help them gain muscle mass. However, individuals many times train hard without the proper diet to add extra pounds of muscle.
Some individuals find it very difficult to gain weight simply because of their genetic make-up.
Just as losing weight takes patience and perseverance, so does gaining weight for many individuals. Because muscle is mostly water, only 2500 extra calories are needed to gain a pound of muscle, compared to 3500 excess calories to make a pound of fat. Most of the extra calories needed for weight gain should come from complex carbohydrates such as breads, cereals, potatoes, and pasta. The need for extra protein has been highly publicized in bodybuilding magazines and gyms around the country. The body does use more protein with weight training, compared to being sedentary.
