Chinese form of slow physical exercise (3,3)
I believe the answer is:
tai chi
'chinese form of slow physical exercise' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for tai chi that I've seen before include "Chinese system of slow exercise for relaxation, balance and health" , "'Chinese meditation involving slow physical exercise (3,3)'" , "way of exercise" , "Chinese system of self-defence" , "Chinese exercises" .)
