Drink less carbonated drinks, eat less fried food, and then do sit-ups every day, from 60 to 100. Stick to 2~3 months, control diet, and properly say aerobic and anaerobic exercise, you can basically lose weight. It's not so easy just to insist on 100 sit-ups every day. At first, if you don't have the strength to do 20 push-ups, you will feel very tired, let alone do it at once. But as long as you stick to it, it will definitely have an effect.
