The common operation of stretching calves after jumping rope to prevent thickening is as follows: 1. Lift your chest and collect your stomach, take a step forward with your left leg, bend your knee, straighten your right leg, press your body backward, and stretch the calf muscles of your right leg. Hold on for 10 to 20 seconds, change legs and repeat the above action. 2. Lift your chest, stand facing the wall, take a step forward with your left leg, press your forefoot against the wall, press your heel against the floor, and press your body forward. Hold on for 10-20 seconds, change legs and repeat the above actions. 3. Lift your chest and stomach, lift your left leg backward, keep your heel as close to your buttocks as possible, and grab the instep with your left hand to lift it upward. Hold on for 10~20 seconds, change legs and repeat the above action. 4. Separate your legs and align them vertically with the width of your shoulders. Slowly lower your waist, touch the ground with both hands as much as possible, keep your legs straight, and hold on for about 10~20 seconds. In addition to stretching, you can also relax your calf muscles through massage, patting and other actions. Please exercise reasonably under the guidance of professionals to avoid injury.
