Body Type: http://www.muscleandstrength.com/articles/body-types-ectomorph-mesomorph-endomorph.html You could be a variant with an ectomorph upper body and endomorph or mesomorph lower body. Much of this is genetics. You're only 15 so you still have some growing to do. Thin and toned are words used to describe cross country runners, so that is the type of exercise to focus on if that's what you desire.
