Why do women like a man who has a nice toned body all over with his body hair trimmed?

I work out five days a week, keep my body in good shape, and keep my body hair nicely neat and trimmed. I kinda have to anyways because I do modeling for sensual art. I always seem to get a lot of attention from females about how toned my body is, especially my abdominal muscles. I'm not complaining here, but I've always wondered what it is about women and their attractiveness towards a man with a nice toned body.
