Put simply, hypertrophy refers to muscle growth. Whether you are training to bulk up, create definition, or lose weight, hypertrophy will occur as muscles enlarge and grow. There are two types of hypertrophy when referring to muscle growth: myofibrillar and sarcoplasmic.

Myofibrillar refers to the growth of contraction muscles. This type of hypertrophy is ideal for individuals looking to increase their strength, speed, and agility.

Sacroplasmic hypertrophy is an increase in glycogen storage meaning an increase in muscular endurance. This method is best for creating muscular definition or for endurance athletes looking to improve muscle longevity prior to fatigue setting in.
