well i have my answer to why i see alot of people in my MMA classes curling like little curl monkeys. THE INSTRUCTER DOES IT TOO!! I just hope he has a reason for it. The only possible explaination i can think of is that in MT/BJJ you can develop tricep dominance and it needs to be evened out? This is the first time i've seen him do it so i'm going to asume that this is the case.
