One important aspect of power generation in matsubayashi is to shift weight off of one foot and then back to it to add weight to waza. This is initially trained in Pinan kata with the transition from a cat stance to a flat cat stance. It is then developed further in Naihanchi. And then finally developed even more in the classical kata. This practice brings together several principles of power generation and can be very useful in creating amazing power. At the higher levels the weight shifts become less noticeable and movement is very subtle. Any thoughts?
