d greatest exercise machine

i invented in wat i think the greatest exercise(cardio) 'machine' ever invented....the skateboard....its fun, it makes u sweat, builds up ur courage and increase ur heart rate to a healthy level....my thighs already feelin tight...aww.....

i look like an idiot anyways, so old amongst the kids at go-sport probably the oldest skateshop in sg....anyways, i feel good, progressions pretty fast and i hope it dont stop there, being mature does help u mentally...though the fear is still there and i twisted my knee trying to pull a pop shove it...damn...heee...its fun, ppl out there join in the fun....i already did...
