the problem is that your going to soft on them too. if you feel like you can throw her and get a slurpee then come back. you should do just that. if its a style they teach the same way. its her fault that she choose that style. and this sounds like alot of it could be improved by sparring. everyone is diffrent. i am not a very strong guy. almost everone is stronger than i am includeing women i am almost taller then everyone too. so spar with her tell her mistakes and video tape her while its going on
then show her the tape and what she could have done better and etc.
so go harder on them. they willl figure the rest out on their own. if they take one punch then get outta there. its kung fu expect to get a little hurt
"you might be in a fake cma school if your master claims to teach a style secretly passed down to him & nobody else called the Five Deadly Venoms"-forgot who
"With kungfu, if it is good method you will build the body and the mind. when these are strong, the spirit flourishes. That's the core of kungfu and again it circles back to 'you'."- david jamieson
P.S. i could be completely wrong
