What kind of body does he think I have?

Long distance runners tend to be more muscular. particularly in their legs and bum. Don't take it badly in my view it's a compliment. I'm built that way and used to compete, now I play hockey for my county as goal keeper. Sprinters tend to be more lean and thin. Their muscles appear finer that long distance runners. Personally I think the more muscular look is more attractive, hence I said it was more of a compliment. I'm not saying you have to be a female body builder (bad look anyway!), but yes long distance runners like me have curvier legs because of muscle not fat and chunkier thighs. Be proud of it ;) xx
