Ok, I'm going to bite the bullet and start a thread! We did this interesting drill at BJJ the other night. Basically, one or both players roll with either one or both hands tucked into (or simply holding) their belts. This will absolutely force you to improve other parts of your game! I don't suggest you do this the whole session but it works well as a warm-up. If rolling no-handed be careful not to smack your face into the mat! Anyone else tried this?
