OMG. Saito Morihiro who said you should practice only kihon waza until sandan?
Wow, a lot of schools don't follow that advice I'd say. I've been with teachers who were his direct students who don't even follow that advice.
Not saying it is bad advice of course, I see how useful the static practice is.
Does your school only perform from static the first 10-15 years of training? When do you incorporate realistic attacks into training?
