Peeling hands: Always that most techniques begin with grip. The hands and feet are the mechanisms of grip in Jiu jitsu – if you can peel those hands off and deny an opponent his it be very hard for him to initiate grappling techniques. Learning to quickly disarm an opponent by peeling off potentially dangerous grips before they can have effects can save you of trouble down the road. Just make sure you don't focus only upon peeling away grips – you can't play a negative game where you only focus on stopping the other guy doing his – you have to them assert your own positive attacking grips and get to work yourself. The cycle of grip breaking and grip assertion is what allows good to shut down an opponents while asserting their own – a hallmark of good Jiu jitsu
