Treadmills are awfully boring, if effective.
I just picked up a Nordic Track and a full set of dumbells for a grand total of $20. Gotta love Craigslist! But now I'm remembering a lot of muscles I'd kinda forgotten about. Oops.
Boring is right. I have a book about the Iraq War on tape that I've been listening to for weeks. It's really very interesting, but the treadmill time still drags!
I got a Gazelle Edge at Wally World a few years ago, and I seem to be walking outside more than in. However, it's good, low-impact exercise for us ol' fogies...;o]
