Yijinjing (Yijinjing) is an introduction which originated in Qin and Han Dynasties. During the Tang and Song Dynasties, it was introduced into Shaolin Temple and became a fitness exercise for monks.

"Yi" is to change, transform and strengthen, "Jin" refers to soft tissues such as meridians and bones, and Yijinjing is a training method to change and strengthen soft tissues such as meridians and bones. "

Tie a standing posture, then put your arms parallel to your shoulders and slowly raise them above your head. These two simple moves are the moves in Yijinjing which are being promoted by many communities in Shanghai. This kind of exercise, which lasts less than 20 minutes, is very helpful to improve the leg weakness and waist and knee weakness of the elderly.

According to legend, Yijinjing was created by Dharma, the early ancestor of Zen Buddhism, in Shaolin Temple for nine years. Originally, it was one of the ways for students of Shanghai College of Traditional Chinese Medicine to exercise. Later, it was adapted by Dr. Gong Li from Yueyang Hospital of Integrated Traditional Chinese and Western Medicine affiliated to Shanghai University of Traditional Chinese Medicine, and the movements were more suitable for middle-aged and elderly people. As one of the third batch of "appropriate technologies for Chinese medicine community" in Shanghai, it began to be popularized in the community.

Hu Weimin, a Chinese doctor who teaches this exercise at Yin Hang Community Health Service Center in Yangpu District, said that from the actual effect of practicing Yijinjing, it can obviously improve the situation that the elderly are tired of walking and their legs are boring.

Due to the increase of age, from the age of 25 to 50, the number of human skeletal muscles began to decrease at a rate of 4% per 10/0 year. The decrease of muscle quantity and muscle strength will lead to the decline of leg motor function, which is characterized by slow movement, stumbling, balance disorder and easy to fall. This set of aerobics has many movements, such as lunging and looking up, which can exercise the meridians of the legs, promote blood circulation and increase the muscle strength of the legs.

Compared with Tai Ji Chuan, this set of movements has only 12 movements, and the difficulty coefficient of each movement is not big. Just "stretch your arms and tie a posture" is enough. Doing a set of exercises for about 20 minutes can make you sweat a little, regardless of the venue. The venue is not big, so you can practice watching TV or listening to the radio. Very suitable for the elderly to learn.
