The number of exposed blocks of rectus abdominis also mainly depends on genetic genes. During the exercise, in addition to sit-ups, wing abdomen, kneeling posture, weight-bearing abdomen, you can also do some extra exercises for the lower abdomen, such as leg lifting, supine air treadmill, horizontal bar hanging abdomen, etc., to enhance the exercise of the lower abdomen. At the same time, in the exercise plan, there should also be exercises for abdominal oblique muscles (including external oblique muscles and internal oblique muscles) to make the waist and abdomen more stereoscopic. In specific actions, you can use sit-ups and hanging belly rotation, or you can use bell-holding lateral flexion to strengthen the external oblique muscle, but the amplitude and load of lateral flexion should not be too large.
