Did you ever try arm wrestling?
yes, many times i was approached by proclaimed world caliber arm wrestlers. they would always say they never wrestled anyone that looked like me and would i mind if they tried. i have never lost.
now my connective tissue is too messed up and i would pop a tendon or ligament before my muscle would fail.
i learnt the technique when i was young, so that helped. same as fighting. big muscles don't make you win, but if you have the ability to
win the stronger you get the better.
