Over 130 participants are gathered for Fall Tai Chi week, lead by Marsha Eberhardt, at the International Centre in Orangeville. We worked together on our Tor-yu, one of our foundations, and continued to explore our feet, the foundation we stand on. We discussed the physics of the 49/51 forces coming from our foundation and put it into practice. We learned how physiology and tai chi practice encompass all systems of the body with detailed presentations on the feet and the brain. We even found the spring muscle in our feet and got to know the Latissimus dorsi muscle and practiced its influence on the movements.
