sit-up
Lie flat on the ground, cross your hands on your chest, and bend your legs slightly, such as sit-ups. Get up and lie down and repeat several times. As for the number of times, it can be decided according to personal physique. People who have poor physical strength or haven't exercised for a long time can use other help, such as hooking their feet with the help of a wardrobe drawer, or asking someone to hold down the instep to get up. In addition, stretching your hands forward or gently putting your head behind your back can help athletes get up easily. Although the effect is not as good as putting your hands across your chest, it is very suitable for beginners with beer bellies to practice.
Bend your knees sideways and lift your legs.
When you use an armchair, your legs naturally fall to the ground, your hands are crossed on your chest, and your knees are bent to lift your legs. Similarly, the hips must be close to the chair surface, even if the legs are lifted sideways, they should be parallel to the chair surface as far as possible and should not be lifted too high. Repeat several times and be the other side.
Side abdominal muscle training
Put one hand behind your ear and one hand close to the ground. Do sit-ups in the left and right directions, and repeat several times. When doing this group of movements, the back must be close to the ground, and the hips standing sideways can only be slightly raised, not too far from the ground, otherwise it will easily lead to back injuries.
