It has been a very long time since I pulled sumo (about 3 years or so). I used to pull sumo all the time, though I'm not sure my technique was every really all that great. I've always had a problem with the weight coming forward when I break the floor. As the video below shows, I also seem to not be getting my chest up as much as I should. Tips for fixing both problems? Anything else you see that I need to work on?
