5' 8", 17 yr old, and I bike, shoot hoops and jog. I do occasional weightlifting (very light...around 5-10 pounds for the most part) but I train for speed, not for power or bulging muscles.
Diet consists of both American food (plain bagel and roast beef, blueberry bagle and yogurt, and occasional Burger King Double Whoppers...of which I can eat two at one meal) and Chinese food (rice, noodles, mantou, tofu, meat, etc). I try to eat healthy and I can get out a lot more now that it's warmer. I'm pretty sure I've grown a bit since I measured last.
BTW: My growth spurt didn't start until I was 15, when I was a sophomore in HS.
