The first aspect: the role of large muscle groups in training before small muscle groups.
The main muscle groups of our body include pectoral muscle, latissimus dorsi muscle, leg muscle and so on. Because large muscle groups play a greater role than small muscle groups in sports, we will train with small muscle groups in training. For example, chest muscle bench press training, we will practice triceps brachii, so practice chest muscle first, then triceps brachii, so the training effect will be better. The large muscle group contains a lot of muscle strength, so it needs to practice three major instrument movements: squat, bench press, hard pull and so on. These are all training methods to stimulate the body's large muscle groups, and we will get more strength effects in training.
The second aspect: from the original state and function of the human body
The joints of our human body are closely connected, and we don't exercise alone in daily exercise. Chest muscles, back muscles, gluteal muscles and leg muscles have been used for a long time, so they have made great progress. This is the initial state and function of our human body. However, at the current pace of work, our amount of exercise is greatly limited, and large muscle groups are rarely mobilized. There is even a feeling that humans don't know their own strength. The proprioception is getting worse and worse, and the muscle strength is getting more and more unbalanced. The posture will be ugly, and you will never do movements that are coordinated with your body, such as squatting. This is the desire to build large muscle groups.
The third aspect: the large muscle group training is more comprehensive, the figure is more symmetrical, and the efficiency is less limited.
Our large muscle group exercises can make shallow muscles and deep muscles get good training. Most muscle exercises are done in a standing position, so that the weight of the human body is supported by the body, and a large number of muscles and bones are stimulated, which makes the exercise range wider and the training more comprehensive. Through the coordinated work of muscles, the muscles that exert their strength actively exert their strength, so that the auxiliary muscles can play a better role, and at the same time, the coordination of the body will be strengthened. But for the training of large muscle groups, there must be a detailed plan, so that the movements can be carried out correctly according to the plan, and the muscles can be exercised more symmetrically to achieve the ideal effect.
The key point of our fitness is to fully understand the present situation of our body, define our exercise goals, find suitable training methods, and achieve unexpected training results. I believe that the charm of exercise itself will make you stick to it, and at the same time see your potential, there will be different physical changes.
