Healthy and flexible joints are the basic guarantee for productive labor and the favorable conditions for carrying out various sports activities. Especially those who practice martial arts need healthy and flexible joints. Baguazhang pays attention to the exercise of all joints of human body. People who practice the eight diagrams palm all the year round are not only flexible and robust in each joint, but also have a larger rotation range than ordinary people. This role of Bagua Palm is incomparable to other sports or other boxing.

Baguazhang is the most famous. The eight diagrams step has both the transformation of virtual and real legs and the buckle and swing when turning around. Doing a good job of spike and swing requires the coordinated action of hip joint, knee joint and ankle joint, which is not available in other boxing methods.

There are many formulas for practicing waist in the action of Bagua Palm, such as "pulling out the top with empty chest and collapsing the waist", "bending your knees and twisting your hips and feet" and "loosening your hips and growing your waist and drilling with steps". Some movements of Bagua Palm can be accomplished not only by waist movements, but also by coordinated movements of spine, cervical vertebra and thoracic vertebra. Now people's living standards have generally improved, but their physical strength is not as good as before. The reason is that with the progress of science and technology, people's physical labor is getting less and less, and young people rarely take part in sports, so more and more people suffer from low back pain and neck pain. What "cervical protrusion", "lumbar protrusion", "numbness of hands and feet" and "unable to lift arms" appeared one after another. Drug treatment can relieve pain, but it is difficult to eradicate it. If these people practice Bagua Palm at the same time of medical treatment, they can get twice the result with half the effort. People who don't have these problems can avoid them by practicing the eight diagrams. In the ten years since I held the Bagua Palm Training Course, many people have experienced low back and leg pain, and the effect of a single injection is not good, but they all recovered after insisting on practicing Bagua Palm. Among these people, there are more than a dozen veteran comrades in their 70 s who used to have difficulty walking and ran to the hospital all the year round. After practicing the eight diagrams palm, not only their waist and legs improved, but also their blood pressure returned to normal.
