Re: static vs. dynamic waza
Since you're from Yuishinkai, you got to trust Koretoshi Maruyama sensei, he is a great teacher, he knows how to teach his students the best way.
Static training is for sure the most important training in any sporting arts, as well as in Aikido. It's how we learn the basics. Once we (mind and body) get the basics, the dynamic techniques come naturally.
