i got subbed by a woman in my intro class which was to be expected, even with me being significantly larger than her. as time went on she continued to work me but i never got subbed again. she was the reason i signed up.
moving forward, we got alot of tough women at our school and while i don't get to roll with them often, they will seek out bigger dudes after class for extra rolls and furhter confirm what i already know...these women are tough.
i won't speak for all women training but the attribute all the women ive rolled with had was finesse and that is something you don't get from rolling with dudes who's sole purpose is to smash (especially bigger dudes), though i believe it has its place in training. when i was coming back from my l4-l5 disc replacement surgery, it was rolling with women and smaller dudes that helped me regain the finesse that left while i was convalescing and that now helps me deal with bigger, stronger dude better.
