When doing it, just pay attention to easy stretching, and repeat each section 8 to 12 times.
Section 1: Hold the trunk or the wall with both hands and lean forward slightly. Stepping in place with both legs, keep your toes off the ground, and speed from slow to fast.
Section 2: Stand with your feet shoulder-width apart, bend your body 90 degrees, and stretch your arms forward at the same time.
Section 3: Stand with both hands on the trunk. Alternately, bend your knees and raise your legs, and the range of motion should be large. When one leg is raised, the support leg lifts the rear heel. Hold for a while and then switch to the other leg.
Section 4: Stand with feet apart and shoulder width apart. Lift your arms to the right, straighten your left leg, and bend your right leg.
Section 5: Stand with your back to the trunk and hold the trunk with both hands behind your back. Alternately bend the knees and raise the legs, with the calves slightly outward. Switch legs and do it again.
