Im aged 15, 5ft 6 1/2 and i weigh 220lbs so im fatter.
I want to be taller and slimer (even though i'm probably going to stop growing taller soon, i've only recently started to have growth pains in my legs so i might be taller yet ) oh and the other reason im want to be slimer is that during pubity your muscles develope and that when its best to get stronger and fiiter because it gives you a boost in the upcoming years to be stronger.
Oh i hate football/soccer so that out of the question but i do love cycling so that might help a lot to.
Oh and blade5x how long in your 1-2 times a day (is it 20min because im sure i've heard somewhere that its good to have 20mins of exercise at least a day to get fit and live healthy).
