1, starting position: supine, knees bent, legs bent to 60? The left and right feet naturally lie flat on the ground separately, with hands behind the neck.

2. Action process: slowly bend the shoulder to the knee until the scapula is off the ground, reaching the "peak contraction" position, and then pause. Then, return to the starting position.

3, action essentials: when the upper body is lifted, the upper back should be kept in a natural state to avoid muscle resistance and reduce neck pressure. Don't move too fast, slowly lift and lower, and fully press the abdominal muscles.

4, breathing method: inhale, bend over, lift the trunk. Exhale after the action is completed.

Easy mistake: cross your head behind your head.

Tip: the upper body should bend forward too much, and keep the abdominal muscles tense at all times.
