I love Taiji Yin Yang Symbol Sticking Hands training. Those who attended the earlier Training Camps in CA can attest that the hours of solo and partner Sticking Hands we practiced daily gives a deeper feeling of Qi, and the "threaded-together" connection of the body. It leads to an understanding of the concepts of listening, adhering, neutralizing, and Jin.
Its also very pleasant training that builds the entire body gradually.
