I'm 15, I'm a little out of shape. I'm kind of scrawny, you know. Skinny wrists, skinny arms, a bony chest, and shoulder blades stick out a bit (but I'm working on fixing that, go dumb bells, go!). I'm 120 pounds, and I feel like all of that weight is in legs.
I'm basically looking for some tips on a daily routine to help me gain some weightand put on some muscle. goal is to be nice and toned, not really overbuffed (if thats a word). I want a nice chest and nice arms like everyone else,

I own two 10 pound dumb bells, two 15 pounders, and two 20 pounders, but I have the resources to get more equipment. I used to use them, but now the spiders have turned them into their home.
I jog around the street every day, so I think I'm fine cardio wise.
I seriously appreciate any help you guys could give me.
BTW, does lifting stunt your growth?!
