Fitness

I'm 5'something and 100 lbs.
Waif-like in appearance and no weights or anything. The closest thing to exercise I have involves:
- (arms) - drummania, taiko drum master, piano pieces with lots of octave chords
- (legs) - ddr, random walking to the mall/around town

I usually associate having to exercise with larger people. I don't really seem to gain weight, however much I eat and I don't mind people calling me out on how thin I am, so I don't bother exercising.
I might want to be slightly muscular, but definitely not too much, but that would involve many sessions of lifting weights.

Jam it back in, in the dark.
