Sit-ups, breaking up in bed, lifting your feet and pedaling your bike, at least 100 or 100 times a night, will have initial effect in 7 days, and it will definitely be smaller in one month, so you can't be lazy. In addition, eating cold melon (also called bitter gourd) and winter melon in summer can reduce fat. If you still want to use external force, buy Clarins' abdominal fat-eliminating massage cream and go to the beauty salon to rub it for the doctor, if you are not afraid of pain.
