Think about what you are saying you think that as a man you are stronger the a woman because your muscles are bigger right... wrong. You may be able to lift heavier loads and produce more power over a short time. But it is the skinny well tone ones who can ride longer at a high power out put.
You crank it up 400w for 5 min... I stick with 150w over the next 5 hrs. I am a "skinny guy" who has learned to enjoy the view from the backside.
BTW who are you trying to impress with your picture uh???
