Have too many friends these days? Tired of everyone fighting to partner with you during open mat? Invisible Jiu-Jitsu has a non-wrist lock solution you can try out immediately: The 328% More Painful Kimura! (Actual percentage of pain may vary by individual softness.)
It’s nothing fancy. All you’re doing is squeezing and pushing your opponent away with your legs once your hands are in position, pulling the shoulder out of its socket before rotating to complete the submission. It’s 1-2 extra seconds of work for a faster tap and lowered resistance.
