Although I don't know if it has any effect, if I want to lose weight, I must first find the reason for my big belly. If it is because of drinking too much or eating too much, you can adjust yourself and exercise a little, and your stomach may be smaller. Jumping exercises such as running, skipping and aerobics are quite effective in reducing stomach. You can try, but this season is not suitable for losing weight, because winter is the time for your body to store fat, so you can consider losing weight in summer. During the summer vacation, the time is quite suitable and it is easy to sweat. In addition, it is recommended not to turn the hula hoop more, because these things may cause damage to the soft tissue of the body, or twist the waist and hurt the bone. It's safer to exercise yourself and take care of yourself.
