Action: Jump upward with force as a whole. After jumping, cross your feet back and forth and land, then jump upward with force and change sides. Your arms naturally swing back and forth with the leg movements. The whole movement is continuous and elastic.

Exercise site: Leg: As the leg swings back and forth, it will directly stimulate quadriceps femoris and indirectly stimulate hamstring. Shoulder: the arm swinging back and forth is similar to the front flat lift, which will stimulate the toe of deltoid muscle. Hip: In the process of swinging the legs back and forth, they will contract to the gluteal muscles and play a role in exercising the hips.
