Second, walk: swing your arms greatly and move forward vigorously.
Third, running: run in small steps, put your hands on your shoulders at the same time, and bend your elbows forward; Then run and jump 25-50 meters quickly. Repeat 4-6 times, with a break between each time.
Fourth, stretching: stand on tiptoe, straighten your arms up, and then stretch in all directions. Repeat 6-8 times with a short break.
Five, hanging: hanging on the horizontal bar (20 seconds to 1 minute), legs together. First turn your body left and right, then swing back and forth, and finally do pull-ups (girls can keep their feet off the ground by doing this exercise). Do it for 4-6 minutes each time, and repeat each action 6-8 times. Another way is to keep your upper body upright and squat down, then grab the horizontal bar when you jump up and use inertia to do pull-ups (the height of the horizontal bar and the distance between your hands depend on your personal situation), and repeat several times.
6. Jump: Jump up, try to jump higher than last time, or try to reach a certain height. Jump down, jump down from a slightly higher place, bend your legs as much as possible when landing, then push your feet hard on the ground and jump up again, 30-60 times each.
