The term “muscle hypertrophy” refers to the increase in muscle cell size as a result of resistance training and exercise. This physiological process occurs when the muscles are subjected to stress, leading to micro-tears that subsequently repair and grow larger during recovery. Muscle hypertrophy is primarily driven by factors such as hormonal responses, adequate nutrition, and progressive overload during workouts. Achieving hypertrophy enhances strength, improves physical performance, and contributes to a muscular physique, making it a key goal for many fitness enthusiasts and athletes.
