A quick rant about the absolute easiest way to add effective and proven techniques to your game, namely going through the memory banks and trying to figure out what you used to do that worked great that you then stopped doing for no good reason! Check out my Grapplearts BJJ Master App for iOS and Android for free at https://www.grapplearts.com/masterapp. It comes with a TON of free material on it, including a complete standalone module on weak side back attacks! Good luck with your training! Stephan
