Abs. arm & leg muscles, and pecs?

i'm 14, and 6'3", 130 pounds, very skinny, and have no access to a gym. i can do crunches and sit ups, and push-ups. i have 5 pounds weight and can go running with friends. i have all the time in the world to do exercises, and i don't need them anytime soon, although they'd be nice by august 27th. anyway, advice would be great!

thanks!

well you can do crunches, sit ups and pushups cuz they exercise you arm muscles, your abs, your leg muscles and running is the best activity to lose weight with or to help build muscles because when you run, you exercise your abs, your leg muscles and much more.
