There is a TON of stance training, lol. In fact, the first month or so is purely based on stance training and standing meditation (with a little push hands here and there). To explain the whole curriculum is kind of hard, because I don't know the whole curriculum yet and it all depends on how fast you progress, not the class in general. But I think he tries to make it so that everyone who is first starting out dedicates about a months worth of training to standing meditation and stance training, and developing the control of your chi.
Anyway, I know the basic history of Yiquan, and I know that it came from Xingyiquan, but he (my instructer) doesn't say "okay, now this is the bagua stuff....this is the xingyi stuff...and this is the yiquan stuff..." he just incorperates it all into one. So I just say I'm learning all three, instead of saying "I do Yiquan", even though we focus more on Yiquan stuff then anything, at least so far we are.
