Chronic low back pain is caused by insufficient muscle strength and ligament strength of the waist and poor stability of the lumbar spine. The exercise of "walking backwards" can strengthen the strength of back muscles and enhance the stability and flexibility of lumbar spine. When walking backwards, the waist muscles contract and relax rhythmically, which can better improve the blood circulation of the waist and improve the metabolism of the waist tissue, and has a certain therapeutic effect. I can swim and ride a bike when I am young! I wish you a speedy recovery! !
