How often to lift to achieve muscular hypertrophy? More fibers are produced to make up for the damaged ones, and this is where the actual muscle growth takes place. New muscle fibers are produced to help replace and repair the damaged ones. Muscle fiber repair occurs after the workout, while the muscles are resting. Once damaged, these fibers are then ready to be repaired These muscle fibers are broken down throughout the course of a workout. This repeated contraction during a workout causes damage to the internal muscle fibers. Each time a muscle is exercised, it contracts. Stimulation occurs during the contraction of the muscle-during the actual exercising. There are two essential components necessary for the growth of muscles-stimulation and repair. Over months, the muscle cells begin to grow larger and stronger. This alone often results in strength gains without any noticeable change in muscle size.Īs you continue to exercise, there is a complex interaction of nervous system responses that result in an increase in protein synthesis. When you start exercising a muscle, first there an increase in the nerve impulses that cause muscle contraction.

The way you lift will determine the way your muscles grow and change. When weightlifting, you can perform many repetitions (reps) at a lower weight or lift a heavy weight for fewer reps. When you work out, if you want to tone or improve muscle definition, lifting weights is the most common way to increase hypertrophy. Hypertrophy refers to an increase in muscular size achieved through exercise.

Hypertrophy is an increase and growth of muscle cells.
