So who is this Bruno character you may be asking yourself. Bruno is a third degree Gracie Barra Black Belt and is most well known for awarding GSP his black belt in Montreal.
Now let's get to the point. What happens if your partner/opponent refuses to let go of their deathgrip and Bruno's first technique just happens to fail? Don't fret, we have option two for you which involves a well placed stomp to the arm. While it may be just a step above my leg smash to the face, it's much more kosher for competition.
Watch and learn grapplers!
