I am the only woman cross training between three different schools filled with ten or so men in each. In many of my classes if i do not fully understand a technique they will hit me with more and more power often going overwhelmingly fast too the point that i come out of class the only one covered in bruises. Sometimes the men even though they are two or more feet taller than me get mad when i beat them in sparring. In one case i was knife fighting a man much bigger man than me who had been training for many years to me who had on been training a couple months, when he suddenly got really mad that i kept knife tagging him and leg swept me by surprise, sprained my ankle and i almost cracked my head on the hard wood floor. Alot of times in my classes if i do any technique wrong i pay the price of becoming an example of what not to do before they do a really hard joint lock or smack and or grab my hands and arms really hard to the point i can actually feel my eyes tear up. I love training with the guys and have nothing against men. I have asked them all to go easier on me as i get way too many injuries in classes but nothing really changes. I dont know if its an ego thing or if men just dont know there own strength. Alot of the guys i train with are big muscle builders and are around six feet or taller whereas i am a five foot seven and clearly not threatening looking. I know getting hit is bound to happen and beneficial to learning how to correctly perform a technique but how hard is too hard? Any thoughts?.
