This past week at 10th Planet Van Nuys we went over the arm in guillotine. In the video below Robson Moura goes over his variation of an arm in guillotine. One thing that I really liked about his approach was how we slides down to the elbow before pulling the elbow in. This not only makes your guillotine tighter, but it can also make setting up the gator roll a lot easier. My goal for my one training session at 10th Planet Van Nuys this week before I go on vacation is to try and at least use this little tweak to see if it makes the arm in guillotine or the gator roll easier to hit.
