1. Horizontal bar traction: Horizontal bar traction can increase the strength of muscles around the spine and protect the stability of the spine, thus delaying the degeneration of the spine and avoiding hyperosteogeny and disc herniation.
2. Little Yin Fei: Lie on the bed with the abdomen as the fulcrum, so that the upper end and lower limbs of the body are slowly tilted upward, so that the angle arch is kept in reverse tension, which can exercise the muscles at the back of the whole spine.
3. Five-point support: do supine abdominal lifting, with elbows, head and bilateral heels as fulcrums, slowly lift the abdomen upwards, and then slowly put it down after 2 seconds, so that the muscles before and after the spine can be exercised.
