Well that would depend on what the woman works out, if it's a classic woman workout (meaning to get sexier and not stronger.) Then I doubt it, it also heavily depends on technique. If both are just going to arm wrestle randomly not knowing any of the technique behind it. Well then I would say it would be pretty even, I'd give a 7/10 win ratio for the man. Now if the woman is actually working out to be strong and not a sexy piece of ass, that will give her the majority wins in the contest.
