The team is ready to dance the square dance.

Arrive at the square at least fifteen minutes in advance. Prepare for the activities of limbs. First, move your arms, knees, bilateral waist, front and back waist, ankles, wrists and even neck, and have a good activity. Otherwise, if you start practicing square dance, you will be uncomfortable.

If you do a good' warm-up exercise' every day and your knees still feel uncomfortable, you should consider changing to other fitness methods.

I should also consciously avoid twisting my upper limbs and twisting my left and right knees. When you must do it, you should also pay attention to the safety of your knees.
