Chinese system of exercise and self-defence, using balance and co-ordination with minimum effort (3,3)
I believe the answer is:
tai chi
(Other definitions for tai chi that I've seen before include "Chinese system of slow exercise for relaxation, balance and health" , "Way to cross a fence" , "system of exercises" , "Chinese system of self-defence" , "'Chinese form of slow physical exercise (3,3)'" .)
