Physical fitness is the basic athletic ability of the human body expressed through strength, speed, endurance, coordination, flexibility, agility and other sports qualities. It will become more clear to carry out different physical training for different projects.

As far as arm strength training is concerned, arm muscle stretching can be carried out actively. Active stretching refers to mainly relying on the power of contracting muscles rather than other external forces to maintain the movement in a specific position. Passive stretching refers to using Your own body weight or equipment keeps the limbs in a certain extended position.

Existing physical training generally achieves training purposes by pulling training equipment. However, existing training equipment generally has a fixed training intensity and cannot freely adjust the training intensity according to the trainer's own situation.
