Am i overweight??

YOU ARE NOT FAT!!!  Repeat this to yourself three times every morning that you wake up.  You are healthy, vibrant, and young.  Don't compare yourself to those who are starving themselves before every cover shoot, muscle is SEXY.

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. 

I am the same height and weight, and people tell me im crazy if i think im overweight. So i would assume the same about you. Especially since you work out at the gym, you are fitter than you think. Its deffinetally muscle girl,dont worry.
