10 lbs of extra muscle could have helped.
Interesting...at a certain level, 10 lbs of extra strength seems to hurt my technique.
Yoshinkan stresses forward movement, forward focus. But for the purpose of these drills, I think the backward movement at angles without crossing the feet works well. It allows you to not get set on your heels, to not get 'mobbed', to keep moving and sucsessfully entering on uke when under a lot of pressure. Looks like a good drill to me. I need to do more work like that.
