I got to try this yesterday...my partner was a higher belt and didn't want to tap. I am new in the gym and didn't want to break his arm but it was there for sure. BTW...what do gym owners think of students injuring other students because they won't tap? I know at Kteam it is their fault for not tapping but things are a bit more gentle here. I am a smaller guy and need to crank subs or get out muscled. I had this and a healhook on this guy and he was almost begging me to take home a souvenir...
