It is not only necessary to warm up during exercise, but also better to warm up first for heavy physical exercise or work. If you don't warm up, the most common things are muscle ligament strain and joint injury, and your strength can't reach its limit (some muscles are not awake).

Warm-up is mainly to make cells in all parts of the body active, blood oxygen supply is sufficient, blood flows smoothly, muscles and ligaments have good toughness, joints are lubricated, and the nervous system is excited, so as to better control all parts and achieve coordination.

Therefore, the body can be transformed from a static state to a high-intensity exercise state, and the side effects and injuries to the body can be reduced. The human body, like a car, runs at idle speed to lubricate all parts before running at full load.

Warm-up is an aerobic exercise, which can ensure adequate nutrition in all parts of the body. Fitness equipment belongs to anaerobic exercise, which increases muscle volume, strength and explosive force.
