Walk like that

My spin instructor approached me this morning in the middle of class. I was mid-sprint. She literally got off of her instructor bike in the front of the room to come over to me, quietly sprinting my little heart out in the back corner. She said, "Do you realize that your legs bow out when you sprint? I know you're a good rider, so it's odd. I was thinking, I don't think she walks like that, you know? I mean I've seen you walk. Right? You don't walk like that, do you?"
