Lt. Col. Thomas Lessner goes over the plan with a Schertz “Movin’ on Main” co-instructor during the early April community health event. Lessner was a guest instructor, teaching body flow (a hybrid of tai chi, pilates and yoga) during the event, and will teach again during this weekend’s San Antonio YMCA Siclovia event.
