2. Thin the inner thigh, starting from the standing posture at attention, step forward with your right foot and bend your knees slightly. Put your hands on your waist. When jumping, the left and right feet are exchanged (pay attention to keeping your back straight at this time). Jump up and switch feet, and count one and two at the same time. At the beginning, 10 seconds to do 10 times, and then get used to it and speed up.
3. Stand at attention outside the thin thighs. Lift your right foot to the right and your left hand to the left. At this time, pay attention to the balance of the body. The trick is to kick hard. Gently return to the original position. Do it again on the other side. This action takes about 2 seconds. At the beginning, aim to do it five times in 10 second, and then accelerate after getting used to it. Stand thin, stand at attention with your whole thigh, and put your hands at your sides. Bend your knees and touch your toes with both hands (don't push too hard at this time). The trick is to bend your knees, not your back muscles. Then gently return to the original position. This action takes about 3 seconds. At the beginning, you should aim to do it three times with 10 second, and then accelerate after you get used to it.
