Tai Chi practice is incomplete without some form of Qigong. Qigong combines breath and movements training which enables efficient qi (chi) flow in the body. Qigong practice in conjunction with Tai Chi can lead to tremendous joy and health benefits.
Taichi Internal Arts offer a simple Shibashi (18 movements) Qigong form that is similar to the Yang Tai Chi form. Qigong Shibashi can be learned in a matter of weeks by following the free video as provided here.
The video does not show all the repetitions in order that it is not too long and the file is kept small. The captions show the name of the moves, number of repetitions, and the breathing plan.
Start with eyes looking ahead, knees relaxed, feet at shoulders width apart, palm facing thigh. This is a Wuji 无极 (infinity) stance.
