@Kathi: Well, I kind of want to do both - aerobic, and build strength. So I think I'll do 80 rpm every other day, alternating with 60 rpm. I live in Portland - land o' hills.

@Gypsy: Tons of stairs where I work. I can start by getting off a floor before mine and walk up a flight after lunch. Good idea!

@Catrin: I've never tried Pilates, but I think the library has beginner dvds. For now I think I'll try the step ups (or maybe the lunges), squats, and calf raises. Maybe once a week I should do something completely different though.
