I got pretty jacked women in my family and we play armwrestling often. I have seen them all arm wrestle.
My ex-wife had visibly muscular arms and was into her own unusually strong upper body (for a person of her weight and height). If a friend, female or male, commented on her biceps she'd often put up her arm into an arm wrestling position and offer a challenge. She nearly always won against the women. There are pictures of her on this site I posted years ago.
She challenged me all the time as she increased her arm strength to exhibit those freakishly strong arms.
Ever seen 2 females going at it at arm wrestling in real life?
We had 3 strong girls at school who used to arm wrestle each other (and the boys) and they always struggled to beat each other. All three girls could beat all but 2 of the strongest boys in our class. 2 of the girls remained locked dead level for several minutes.
