2. the posture of the neck. During the whole movement, keep your neck upright, close your chin and close to your throat.

3. You can choose the anti-abdominal movement of hanging leg flexion or hanging knee flexion.

Finally, strong abdominal muscles need relatively little body fat content to show up, and aerobic training and diet control are essential. Wish you success!
