Bigger men strike

Tonight, Tanaka sensei reiterated that I wasn't raising my hands up enough before striking men (面), sashi men (さし面), in particular. I didn't understand him the first time but I think I see now. Because of all the pressure to get faster, my form has been changing and deteriorating. This advice, raise up and hit from above, was what I used to tell beginners in Illinois. I feel kind of ashamed when I realized that I was no longer following my own advice. -_-
