Everyone, I ran across this video and you should all watch it. Sensei Brett often talks about how uchi-komi should be explosive as if you really planned to throw. These folks are doing that. Also, watch their combinations, how explosive and powerful and quickly they move from technique to technique until the throw. We should do that too. Finally, look at their kuzushi – look how high they are pulling the sleeve arm – this is what our kuzushi should be like.
If we practice our uchi-komi slowly, without power, and without real unbalancing with explosive and high sleeve pulls, we will never get a successful throw.
