After judo practice last night, I got to work out with a new bjj/MMA teacher who is coming to the dojo. It was an interesting experience. The language was different, but the techniques were familiar. I'm used to learning techniques based on applying a small set of fundamental principles to a variety of situations and problems. For the bjj there didn't seem to be unifying principles, but every technique was broken down into minute steps that were easy to follow. It was great fun to be a pure student, just keeping my mouth shut and learning what he had to offer.
