Muscle hypertrophy
Videos
Muscle hypertrophy, also known as muscle building involves a hypertrophy or increase in size of skeletal muscle through a growth in size of its component cells. Two factors contribute to hypertrophy:
Athletes use a combination of strength training, diet, and nutritional supplementation to induce muscle hypertrophy.
