The stability of the lumbar spine depends on the spine itself and the muscle system associated with it to jointly maintain, and the muscles around the lumbar spine play an important role in maintaining the exogenous stability of the lumbar spine, while a herniated lumbar disc destroys the intrinsic stability of the lumbar spine, and the atrophy and weakness of the lumbar muscles can be reduced by limiting the activities of lumbar pain and wearing a lumbar girth. Through lumbar back muscle training, the stability of the spine can be strengthened; at the same time, it can ensure that the muscles and the tissues around the spine have strong blood circulation, sufficient energy sources and reserves, accelerate the elimination of metabolic products accumulated in the muscles, and promote the repair of damaged tissues caused by disc herniation; improve the range of joint movement, so that the tense and contracted muscles can be relaxed quickly; it can enhance the strength of the lumbar back muscles, correct poor posture, improve the flexibility of the lumbar back and Adjusting the muscle tone of local muscles strengthens the stability of spinal joints, especially plays a better protective role for the internal and external balance of the spine, helps to restore the physiological curvature of the spine and corrects the deformity of the lumbar spine. 2 ways to exercise the lumbar back muscles: Feiyan point water: prone position, double upper limbs straight against the side of the body, with the head, shoulders drive double upper limbs to the back up; and then double lower limbs straight legs to the back up; finally the two movements at the same time such as the small swallow point water action, repeated 10 to 20 times. Supine arch bridge (i.e., five-point support method): supine position, with two hands crossed waist as a support point, both legs bent knee 90 °, the palms of the feet on the bed, with the head behind the pillow and two elbows to support the upper body, two feet to support the lower body, into a semi-arch bridge shape, lift the torso. When lifting the trunk bridge, the knees are slightly separated to the sides, repeated 10 to 20 times.
