Pull-ups may be a skill that every coach wants to unlock, because this action is handsome and a sense of accomplishment. But this action is also very difficult, few people can complete it, so it gives people the desire to challenge and conquer.
The pull-up is a vertical pulling action, which mainly exercises the back muscles and biceps in front of the forearm, so only the back and the biceps The strength of the head muscles is improved, and this action can be completed gradually. In the fitness course, the upper body pull course is the most popular, and you can practice some pull-ups, such as elastic band-assisted pull-ups and high pull-ups, as well as various rowing movements , The main training is the back muscles.
Many people The pull-up technique can be unlocked by practicing upper body pulling, but some people will always fall into a certain bottleneck and cannot break through. It is found through observation that people who cannot make further breakthroughs cannot do enough exercises of upper limb pulling exercises, but are too attached to upper limb pulling and neglecting upper limb push training. This is the key to failing to break through!
Why does the pushing ability of the upper limbs affect the level of the body's pull up, then we must first actively understand the lower active muscles and active muscles.
The active muscles are the muscle groups that actively contract when you apply force, and the antagonist muscles are the muscle groups that passively stretch when you apply force. For example, when you bend your elbow, your active muscle is the biceps in front of your arm. And your antagonistic muscle is the triceps at the back of your arm. When you stretch your elbowWhen the situation is reversed, the active muscle is the triceps, and the antagonist is the biceps.
When an action is completed, the active muscles and the antagonistic muscles must participate at the same time. The active muscles are responsible for the active contraction, while the antagonistic muscles prevent excessive contraction of the active muscles. . Why confrontation? Because if the antagonistic muscles are not involved in the confrontation, the active muscles will contract excessively, which will lead to incorrect movements and even some joint problems. Therefore, the active and antagonist muscles must be in a relatively balanced state.
The pull-up is to exert force through the muscles of the upper extremity muscles, so the muscles of the upper extremity push are responsible for resisting the force and ensuring that the action can be completed correctly.
