Bend over and crawl to practice abdominal muscles

Put your hands on the ground and keep your body as straight as possible, in a push-up preparation position.

Tighten your abdomen and use your abdomen to exert force. Bend your left leg as close to your chest as possible, then switch to your right leg to complete the target number.

Lift your knees and exhale, extend your legs and inhale. Return to push-up position at the end.

Do 25-30 reps in each group, and do four to six groups every other day. People with lumbar disc herniation or high blood pressure should not train this movement.
