Friends who punch in the gym occasionally, will you feel full of joy after each training? I no longer feel that physical exercise is too boring. It is to better train various postures and turn yourself into a perfect big muscle. Have you ever done this?

On the contrary, some novices are always impatient at the beginning of contact training, but they have not shown it clearly after working hard for so long. In fact, in addition to the complete movements, there must be some training knowledge to avoid prejudice and misunderstanding. It can be said that this is a very profound lesson, and our usual smiles are inseparable from muscle movement. How do muscles work?

Like the subtle expressions when we usually talk and chat, all kinds of movements in life are inseparable from muscle movement. We have all kinds of large and small muscles, such as smooth muscle and skeletal muscle, among which there are more than 600 skeletal muscles, which are the muscles that make our bones move, and the muscles of the sports system are the muscles that our limbs and trunk move freely at ordinary times.

Under the control of nerves, muscles contract to produce movement. When we are training, we are actually exerting our strength. What is the process of action from start to finish?

To put it simply, this series of actions is actually the action that each muscle segment forms myofilaments, then muscle fibers, and finally forms the whole muscle group. Of course, controlling the contraction and movement of muscle cells comes from brain consciousness. This series of activities before contraction will be excited by motor neurons and nerve impulses. When nerve impulses are transmitted to nerve endings and then through a series of nerves, muscle fibers will eventually produce action potentials, which will cause muscle contraction.

Although this knowledge seems boring, careful consideration can still help us change the mode and plan of various activities in the later training.
