Lie on your back and cross-touch your toes to exercise abdominal muscles

Mainly exercise the abdominal muscles. Lie flat on the floor or yoga mat, put your legs together and straighten them naturally, and touch the back of your head or neck with your hands without holding them hard. When sitting up, cross your legs and hands in turn to touch the instep, use the hips as the axis to fold the body in half, and then return to the original shape. Do 3-4 groups each time, 15-20 times per group, and exercise 3-5 times a week. You can do exercise after getting up in the morning or after doing other exercises. See the figure below for details.
