The "relax taiso" program, a five minute low-impact aerobic training program created by Koichi Tohei Sensei , can be practiced by anyone of any age. With its focus on rhythm and oneness of mind and body, regular practice of relax taiso can improve physical stability and mental concentration. When taught as a component of Ki training , the series of movements become powerfully relaxed-- the same type of relaxation practiced by students of Shin Shin Toitsu aikido (Aikido with Mind and Body Coordination). Classes can brought to any community and may be started by groups as small as 6 students.
