1, ordinary level sit-ups

Lie flat on the ground, cross your hands on your chest, bend your legs slightly, get up and lie down. You can repeat it according to your physical strength.

2. Upgraded version of sit-ups

If people who exercise for a long time want to increase the difficulty, they can try to cross their feet and do sit-ups. The difficulty is higher than the first group, and the effect is stronger than the first group. This group of exercises can strengthen the exercise of upper abdominal muscles.

In addition, you can also use a round stool instead of lifting your legs: take a round stool with a moderate height and put your feet on it, keeping a 90-degree right angle with your body. This can reduce the burden on beginners, but the effect is the same as that of people crossing their legs.

3. Lie flat, bend your knees and lift your legs

Lie flat on the ground, keep your hands close to the floor, bend your legs, raise your knees (the fatter you are, the more bent your knees will be), then put them down and repeat them several times, which will help to exercise your lower abdominal muscles.

4. Half-lying knees and leg lifts

Sit on the floor with your hips as the fulcrum, hold your arms on the ground, bend your legs and lift them, then put them down. Obese men can effectively contract the lower abdomen in this way.

5. 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.
