Remarks: The above five movements are unisex, and it is best to do them after 30 minutes of aerobic exercise (such as running, brisk walking, swimming, mountain climbing, etc.). ). Because partial weight loss can get better results after full-body exercise! If you feel too tired to do all five movements, you are free to choose three. I believe that through hard work, you can definitely have a flat abdomen, even a stylish abdominal muscle!
