The most common problem of shoulder opening is that there will be a tingling sensation in the lumbar spine after practice. When opening the shoulder, if the flexibility is not good and the strength is not properly controlled, it is easy to cause lumbar injury. Long-term practice of shoulder opening will cause serious compression and wear of the spine.

Shoulder opening movement is a process from stiffness to softness. If you don't pay attention to the rules, opening your shoulders is also a process that is easy to get hurt. Some people like to open their shoulders with the waist of the spine, which will be harmful to their health. Long-term practice will cause serious compression and wear of the spine. So if you choose the wrong way to open your shoulders, it will hurt your health.

Shoulder opening skill: pull the scarf with both hands, slightly wider than the shoulder width, then hold it up and slowly pull it back until it can't be pulled. Stand up straight and don't cover your stomach.

Stand up straight first, then put your arms back, cross your fingers and close them, and then let your closed hands stretch down and back as far as possible until they can bear it. Be careful not to burst your belly.

The shoulder joint is also a ball-and-socket joint, which moves in six directions. They are flexion (arm raised), extension (forward extension), external rotation (thumb outward), internal rotation (thumb inward), abduction (arm flat) and adduction (bird king style). When these six directions are flexible, the shoulders are open.
