You can choose walking, jogging, skipping and other ways to exercise, or you can turn a hula hoop! If you can't jump rope at home or in the office, you can choose to jump in place. The general exercise time is about 30 minutes, but it varies from person to person. You must step by step, and don't rush for success. Remember, do some stretching exercises after running, or find a chest-high place, leg press. The method is to put your toes on your face and pat your calves at the same time. The purpose of this is to stretch and relax the muscles of your calf. It won't be a block, but a strip, which will look very thin.
