腹肌是人体缔结组织中的重要组成部分，包括腹外斜肌、腹直肌、腹内斜肌和腹横肌。当腹肌收缩时，可以使躯干发生旋转和弯曲，并可以防止骨盆前倾。腹部肌肉对于腰椎的活动和稳定性也有着非常重要的作用，可以控制骨盆和脊柱的活动。软弱无力的腹肌可能导致腰椎生理弯曲增加和骨盆前倾，并增加腰背痛的概率。因此，女性产后腹肌锻炼显得尤为重要，现有腹肌训练的方法一般为借助健腹机锻炼，具有良好的锻炼效果。The abdominal muscles are an important part of the connective tissue in the human body, including the external oblique, rectus abdominis, internal oblique and transverse abdominis. When the abdominal muscles contract, they allow the torso to rotate and flex and prevent the pelvis from tilting forward. The abdominal muscles also play a very important role in the mobility and stability of the lumbar spine, controlling the movement of the pelvis and spine. Weak abdominal muscles may lead to increased physical curvature of the lumbar spine and anterior pelvic tilt, and increase the probability of low back pain. Therefore, postpartum abdominal muscle exercise for women is particularly important. The existing abdominal muscle training method is generally exercising with the help of an abdominal fitness machine, which has a good exercise effect.
