The principle of muscle growth, muscle growth is the destruction of muscle fibers by high-intensity training. In the future, muscles will be repaired through sleep and high-protein diet, and muscle fibers will increase during the repair process. The body wakes up in the morning and is full of energy all day.

Do more leg training, many people think that having abdominal muscles and showing an inverted triangle is a good figure, so focusing on chest and abdomen training and paying less attention to leg training is of great benefit to muscle gain. Leg muscles are the largest muscle group in the human body. Leg exercise can improve male testosterone secretion and promote the development of whole body muscles. Studies have shown that leg training can even promote the growth of arm muscles.

Proper aerobic exercise can not only enhance endurance and overall training intensity, but also improve cardiopulmonary function and body health index, control sebum and avoid muscle gain and obesity. Therefore, muscle building requires aerobic exercise, but it can be controlled 2~3 times a week for 30~40 minutes each time. It is best to separate from strength training. Jogging, swimming, cycling, walking, running in situ and aerobic exercise are all good choices.

Using heavy strength training is the primary factor to increase muscle, and we must try our best to stimulate muscle growth. Without this, your body has no reason to use those extra calories to help you grow muscles. Therefore, it is very important to give muscles enough stimulation. The stimulation of compound movements on muscles is irreplaceable. The bigger and more muscle groups involved in the action, the higher the load, the more it can stimulate the secretion of testosterone. Therefore, it is necessary to practice squat, bench press, hard pull, push and other super-heavy muscle groups.
