Pay attention to the activities of shoulders, waist and ankles first. These three parts should be warmed up slowly, preferably not less than 15 minutes in advance, with knees and feet together, slowly turning around and twisting, and one of them is indispensable.

This kind of warm-up exercise must be done, and the warm-up period should be no less than 5 minutes. Rushing into battle will hurt your limbs. During the warm-up stage, it is forbidden to laugh and fight, and you can do your own independent soothing activities. It will never stop without talking to people. This will delay the progress of preheating. When a group activity is called, you are not ready and hurt, but you are in pain.
