I agree bro, my biceps are huge and guess what, yeah, I was beaten by someone who was a BIT smaller than I. I wasn't mad or anything, but I for sure know that it's not all about the biceps. I see it in the Tricep region as well as the side shoulder pads. Biceps are too in the muscle group to arm wrestle but not as much as you think. Also, the OUTER chest muscle area if you notice does take some effect or degree on it. But yeah, I don't like to arm wrestle, I perfer a flat out wrestle to the floor pin-em down match

. BUT THE BIG THING IS ITS NOT THE MASS ITS THE STRENGTH! There could be guys bigger than me, but there is NO way anyone can visually say they are stronger than me. THAT'S a fact and same goes out to everyone. Strength and Mass are two different things.
