1, swimming to lose weight: swimming for 30 minutes can consume 1 100 kilojoules of heat. Even if people are no longer in the water, their metabolism is still very fast and they can consume fat faster than usual. This method is the most scientific and undeniable. Swimming can not only close the abdomen, but also shape the body. Method: If you want to lose weight, you must swim slowly and keep a very average speed, so that you can achieve a balance between exercise and breathing. It's best not to stop during the whole swimming process, just like jogging on the road. If you stop suddenly, it will not only be bad for your health, but also greatly reduce the effect. You'd rather slow down than stop.

2, deformation sit-ups: this kind of exercise is particularly effective for people with large abdomen. Methods: Lie at the end of the bed, keep it outside the bed below the hips, and then bend your knees so that your thighs are above your abdomen. Put your hands on your sides and palms under your hips. Next, you should tuck in your abdomen, straighten your legs forward at a speed of slowly counting to 10 to make your body in a straight line, then bend your knees at a speed of counting to 5 and return your thighs to their original positions. Pay attention to relax your back, shoulders and arms, and feel your stomach working.

3. Sitting on the chair for abdominal exercises: This group of exercises is convenient, easy and fast, and is suitable for practicing every day or every other day. Method: Sit on the edge of an armchair, hold the back of the chair with both hands, and feel that the human body seems to be slipping off the chair. Relax your back and step on your waist, and try to stick your waist on the chair surface. At the same time, both feet take turns to pedal the bike. At this time, the leg muscles should be relaxed, and one foot should be extended downward. The lower the better, but the other foot should not touch the ground. The higher the better, practice repeatedly and insist on it 20 times a day.
