Don't even have to walk outside. Just wait for a personal trainer to walk past with their latest McBeetus Bride/Groom. They'll be on their way to/from a lot of stretching. Then they'll be doing some unweighted squats, followed by some kind of thing where they lay on their back and groan (I think it's called living?)  Anyway, those people don't motivate me. Seeing other people lifting more than me motivates me. I want to OHP that much. Better kick ass today.
