A class you may not know even existed on campus is one that brings energy, lightness, balance, calmness and clarity. Fred Popeski is teaching a tai chi and qi gong class in the rec center.  Using the life force (chi), Mr. Popeski teaches students a system of physical exercise to improve and maintain health. Tai chi can be helpful in achieving a state of physical and mental relaxation, while also strengthening the cardiovascular and immune systems.
