A gymnast qualifies as an athlete and from what you were saying about muscle mass, you are not fat. Your BMI should be pretty close to that weight anyway. Girl! What are you talking about??? Throw your scale away and do like all of your 5'7 friends already do, LIE. You already look 10 pounds thinner than you weigh anyway. Oh, and lie on your license too! You are now, officially 135 pounds.
