At the end of the sold-out Super Seminar in Vancouver, Rener decided to roll with some of the participants. Nursing a shoulder injury, Rener decided to tie down his right arm under his belt. Since some of the sparring sessions were recorded by the students, Rener went ahead and narrated over the footage so you could learn a few tricks to up your one-handed sparring game! If you enjoy the rolls, leave a comment and share it with your jiu-jitsu family! Special thanks to Jimmy for the footage and
