... The exercise model had been validated by 3 experts and valid to be used to improve muscle mass up to 1,54. Meanwhile, the fitness exercise model could improve the body composition up to 0,61, improve the muscle strength and durability up to 1,92, improve the muscle flexibility up to 0,06, and improve the lung and heart capacity up to 0,72. Based on the research result, it concludes that: the exercise model which was developed had been tested for its feasibility and function to improve fitness and muscle hypertrophy of students who live in boarding house.
