Re: The MOST important technique?
I only took BJJ for a few months, years ago, but I had that same problem with the warm up roll, or actually all the rolling. The instructor often talked about having an attitude of sticking to the principles, not getting too muscle-y and not worrying about getting tapped. However, there was no time in class, ever, when everyone but me wasn't straining and fighting for every millimeter like it was a struggle to the death. I would have appreciated time set aside for a rolling practice that emphasized yielding and relaxation. It was exactly the converse of the problem we have been complaining about in Aikido.
