Do any of you have any exercises, sets, drills, or anything that you do at the gym without a partner, that you do specifically to help your grappling ability? I do lots of shrimping, bridging, elbow escaping, and lots of wrestler sit-out. I also do lunges a lot to help with single-legs and double-legs. Anyone have anything they enjoy doing? I know some people throw their gi over a pull-up bar and do that, do you find that actually helps? Etc., discuss!
