Isn't real resistance fighting back. Instead of not trying to be pulled down, pinned, ... ?
Maybe for you this is what you mean, by fighting back. See below. What I meant by resistance, is a non-cooperating uke. Trust me, I tested this with my 4dan sensei and he had to do similar techniques. I trained in Burmese Bando for 5 years prior to Aikido and learned how to punch and kick pretty good. He almost never could grab my hand exactly. I unleashed several punches to his head, lower stomach area. Most of them landed. I was trying to really make him feel my kicks and punches. He had to grab me, sort of like what you see in the video in order to execute an Aikido technique. Definitely not anything like the demonstrations on the internet. Demonstrations are just that, simply a well thought out demonstration.
