Sit-ups are classic exercises for abdominal muscles, which can effectively tighten the abdominal muscles. Lie on the ground, bend your knees, put your arms across your chest, then get up slowly, try to get your stomach close to your knees, and then slowly lower yourself.

2. Flat bracket

Flat support can exercise abdominal muscles, back muscles and waist muscles, so that the whole core area can be exercised. Lie on the ground, elbows on the ground, put your weight on your forearms and toes, and keep your abdomen tense for 20 to 30 seconds.

3. Abdominal breathing

Abdominal breathing is helpful to effectively eliminate abdominal obesity and improve body posture and balance. Sit, put your hands on your abdomen, take a deep breath, let your abdomen expand outward, then exhale slowly, tighten your abdomen and let the gas out as much as possible.

Lift your legs on one knee.

One knee leg lift is a simple and effective action to exercise abdominal muscles. Lie on the ground, bend your knees, put your feet on the ground, then lift one leg until the thigh makes a 45-degree angle with the torso, and then slowly put it back in place. Practice your legs alternately.
