Give you four movements: sit-ups, sit-ups to lift legs, two-ended lifting, and hanging legs (the intensity is increasing in turn). If you can do 10 to 20 sit-ups, do sit-ups and leg lifts; If you can do 10 to 20 supine leg lifts, you can do both ends. And so on. Practice three times a week, and practice about three groups in one movement at a time. If you can't do sit-ups, you can practice belly rolling.

In addition, fat with a body fat rate higher than 10% will cover abdominal muscles. This is why sumo has no muscles. If the landlord has a small belly, he needs to jog for about 40 minutes to lose fat. About 3 to 5 times a week. If you can't run for 40 minutes at a time, you can walk for a while.
