This Muscle-Building Workout Will Build Mass and Muscle. Bulk up and gain muscle with our 30-day transformation programs for skinny guys. People are best able to improve their muscle mass by performing the right exercises and eating particular foods. Muscle size increases when a person continually challenges the muscles to deal with higher levels of resistance or weight. This process is known as muscle hypertrophy. Our programs are designed to build muscle via the right balance of mass-building exercises, sufficient volume and intensity-boosting techniques.
