Walking backwards can reduce the burden on the lumbar spine to a certain extent. When walking backwards, the center of gravity of the body is relatively backward, compared to walking forward, the vertebrae bear the weight of the body is relatively reduced, and if there is a herniated disc, when walking backwards, the two vertebrae squeeze the disc forward, due to the disc backward herniation tendency to reduce the herniated disc, the herniated disc symptoms may be reduced. Walking backwards can exercise the muscle strength of the lumbar back, strengthen the strength of the lumbar back muscles, lumbar muscle strength can be enhanced to compensate for part of the lumbar spine, indirectly reduce the burden on the lumbar spine, but also block the lumbar disc herniation backwards. Walking backwards needs to be long period of persistence, each time half an hour is appropriate, if there is discomfort, need to stop resting. At the same time should pay attention to the speed, so as not to fall and get hurt.
