The function of body-building training shoes is to pad the forefoot so that the height of the forefoot is higher than the heel, which can force the center of gravity of the human body to move backward, correct the pelvis to lean forward, and straighten the spine to lift the hips and abdomen. It can optimize and beautify the posture (the same as the model standing against the wall), and has a good rehabilitation effect on lumbar muscle strain, low back pain, disc herniation and cervical spondylosis (equivalent to walking backwards).
