Spring stretching can exercise physical strength, increase the three-dimensional sense of muscles, and exercise arm muscles and chest muscles well.

The benefits of spring tension are as follows:

Biceps biceps brachii is a muscle with two muscle heads, and its main function is to bend the arm. Another muscle, the brachialis, is also used when bending the arm. However, the brachial muscle can only be exercised when doing some forearm lifting exercises, such as bending the high-position puller or anti-high-position puller toys. In addition, the brachioradialis muscle, the main muscle of the upper forearm, also plays a lot of roles in arm bending. The brachioradialis muscle can be strengthened by lateral bending of the stretcher.
