Aerobic exercise takes more than 40 minutes to effectively reduce fat, no more than two hours a day and no more than five days a week. When running, your feet should follow the ground and then go to the soles of your feet. It is not easy to form muscle legs. After running, you should massage and relax. It is very important to warm up and stretch before, and stretch and massage to relax after finishing.
