Abdominal muscles are very important for human exercise. Abdominal muscles are an important part of human connective tissue, including
Rectus abdominis,
Abdominal oblique muscle,
obliquus internus abdominis
Transverse abdominal muscle.
When they contract, they can bend and rotate the trunk to prevent the pelvis from leaning forward.
Abdominal muscles also play an important role in the activity and stability of lumbar spine, and can also control the activity of pelvis and spine.
Abdominal muscle weakness may lead to pelvic forward tilt and increase the physiological curvature of lumbar spine, increasing the chance of low back pain.
If you want to have a very high physical quality or competitive level in competitive sports and even in daily life, you can't do without waist and abdomen strength.

Here is a small way to exercise abdominal muscles.
Supine belly roll:
Training site: upper part of rectus abdominis
Action essentials: lie on your back, keep your thighs and calves at 90 degrees, open your feet to shoulder width, and cross your hands over your shoulders. Exhale the head, lift the shoulder blades off the ground, and inhale again. Be careful, don't hold your head hard with your arms, so as not to oppress the cervical vertebra.
Supine roll:
Training site: internal oblique muscle and external oblique muscle.
Action essentials: lie on your back, keep your thighs and calves at 90 degrees, open your feet to shoulder width, and cross your hands over your shoulders. Exhale the head, lift the scapula off the ground, and rotate at the same time, turning the right shoulder to the left knee position. Note: Don't hold your head in your arms, so as not to oppress the cervical vertebra. At the same time, control muscle strength when lifting, and don't be too stiff.
Reverse abdominal roll:
Training site: lower part of rectus abdominis
Action essentials: lie on your back, put your feet together, raise your knees perpendicular to your pelvis, and put your hands on your sides. Look ahead, roll up and lift off the ground, and lift the lower half of the lumbar spine off the ground. Pay attention to the lumbar spine not to leave the ground too much to avoid excessive pressure on the lumbar spine. This action is suitable for middle and advanced trainers.
Flat bracket:
Training site: transverse abdominis muscle
Action essentials: prone, forearms and toes on the ground, chest out and abdomen in, shoulders sinking, head, back, hips and heels in the same straight line. Pay attention to the stability of the body and don't sink too much in the lumbar spine.
