That's why when I was wrestling half my training regimen was spent strengthening my sphincter muscles. One of the better excercises was sticking a roll of quarters up my ass, then I would slowly and deliberately push it back out. I got so good at this the guys would hand me a dollar after practice, asking for change for the soda machine. The first time this was meant to be a joke but when my muscles became so refined that I could give the change to them one quarter at a time, the joke was on them.
The end result was that I became strong enough to lock-in my opponents finger(s) when he tried to check my oil, thereby incapacitating half of his mobility and strength. I can't tell you how many reversal points I scored off this, but it was worth at least two every match.
