On the whole, I think I got a bargain.

The doctor told me to exercise more. (I realize this puts me in a very exclusive club, but hear me out.)

Sears had a sale on treadmills. They had a very nice one for $600 (regularly $900). I was prepared to spend the money when I vaguely remembered that the condo association has an exercise room. Cost: $10 key deposit.

I just got in from 35 minutes with the stationary bike and treadmill. I forgot how good it feels to get the blood pumping like that. I haven't worked myself so hard in years, and it wasn't particularly hard.
