Im 14, weigh 57kg (125lbs??), 6'1" and I am super skinny! But I just keep throwing food in me. Like a non stop power feed for conditoning. *hint hint*
For exercise I just run around at school all day, water changes and give my fingers a great work out on MFK. I love activities. Like for example, tomorrow, Im waking up at 6:30am, riding to my mates house at 7:15, then getting driven to Laser Skirmish with a wad of friends for a b'day. But thing is, it goes till 5:30!!! Gonna be fun. The playing field consists of some 20+ acres. Running is a must. Cant wait till I hit 15 to play paintball!
