What are the practices of hanging health exercises?

Hanging is holding the horizontal bar higher than yourself with both hands, pulling up with both hands, keeping your body as high as possible, and leaving your feet off the ground. Suspension is a tensile load. The two ends of the bone are stretched in opposite directions to resist the compression of the spine, so that the compressed intervertebral disc is relieved and the ligament is stretched, thus preventing the shortening of the spine and the degeneration of the intervertebral disc. Suspension can stretch the muscles of the whole body, reduce the pressure on the waist, improve blood circulation, enhance the functions of shoulders and waist, reduce muscle atrophy and hyperosteogeny, and has a good effect on preventing and treating scapulohumeral periarthritis, backache and hunchback. This is a common problem of middle-aged people. This exercise can also expand the lungs, inhale more oxygen, enhance metabolism and make life full of vitality. The intensity of suspension exercise depends on the individual's physical condition, and the weak can land on their toes (lift their heels). Exercise 2 ~ 3 times a day for 3 ~ 5 minutes each time. Strong people will increase the difficulty, such as doing swings, increasing the extent of stretching the spine and muscles of the whole body.
