I am as short as heck. I think I'm barely around 5'1.
I believe i'm around 135.
Though I am often told I don't look like it at all.
I think most of it's in muscle. I'm not sure.

Once, for absolutely no good reason at all, I pushed my limits on a treadmill severely.
I lost 10 pounds that day, then the next day I had gain twenty.

So. I'm assuming I have 20lbs of muscle in my legs.

I don't really know what to think about myself.
