Erik Paulson on Instagram: "Bob Anderson taught the Americana lock to Rolls Gracie it was taught to him by old Catch wrestlers. Ude Garame in Judo its called or double top wrist lock from catch or The V-armbar from Shooto. Its a shoulder and elbow lock whichever is tighter first and sometimes they both rip. Sounds like a wet towel getting ripped in half. @ruotolos @riganmachado @carlosmachadojiujitsu shout out to Super coach Bob Anderson."
