Hey im 15 years old and im a sophomore in Highschool. Right now im 5'11 , 125 pounds, and 2% body fat percentage. I can curl 90 pound weights 3 times max right now, and i can bench 135 pounds maxed out. I want to know if this is a pretty good spot to be in at my age. Sometimes i work out so much but i feel like i dont go nowhere compared to my friends (my dad says that I just get down on myself too much). If you guys / gurlz can give me reply, and maybe some workout tips to lifting more please help me. Thanks in advance 
Also i want to know if i have more fat, does that mean i have more stuff to burn into muscle?
