So you want to land RNCs like one of the Gordon Brothers, but can’t retain the back reliably enough to start playing with arm in/arm out variations during live rolls. It might be time to take a break from strength training and really examine your literal foundation: foot game.
Jason Scully of Grappler’s Guide is one of the best YouTeachers of technique uploading regularly, and this time he’s breaking down active foot retention and hook game. Beyond the obvious–you know, like sink your hooks first–Scully goes into dominant and weak sides in back mount, the need to manipulate your opponent’s upper body in conjunction with your foot placement, and necessary hip adjustments to insure you keep control. Add this one to your queue for sure.
