JKD & BJJ Rear mount defense

Many important things were worked on today, but what really stuck in my mind/training was the rear mount defense. I need to get my arms lower so that the tips of my crossed hands are right at my jaw bone. Tuck the elbows between the based of the thighs and the body, closing the holes for the hooks. If the hook insertion occurs, the elbows can be used to lift and escape. Very strong, its like trying to sick hooks on a clam -- there's no room. I can make my defense a lot stronger using this set-up, rather than the looser position I've been using.
