I'm glad that my dojos' students (I've been training in 2 dojos) are not very compliant. they love sports so they can put enough resistance. sometimes even too much that I wasn't able to do the technique..
although, the skinny ones can't put up enough resistance I was hoping for..
my previous dojo concentrate on the "Musubi" concept so we have to put forth some pressure against our partners, while my current dojo concentrate on making the techniques work so the teacher gets fussy whenever a student falls on his own..
