right way of doing sitting kokyu-ho
hello there! i'm new here in aikiweb forums and i would like to know what is the right way of doing sitting kokyu-ho? does uke need to tighten the grip and use force so that nage will have a hard time doing this exercise or should uke allow nage to move in order to make a throw? i've been practicing aikido since 1994 and i still have a hard time doing this exercise especially if the uke is very strong. am i doing it wrong or is it uke's fault for resisting?
