Jan, you're too hard on yourself. You are doing great by starting out on the long weekend walks. You don't necessarily have to do something every single day. I'm lucky to be in a fairly warm climate that allows me to be more active (outside) in the winter than a lot of you folks up north. If you are able, sneak in a couple of walks/workouts during the week sometime, but keep up the weekend routine you've started. I'm a morning person, so I do some early morning (before work) runs during the week when I can, then do longer ones on the weekend.
As far as elliptical machines, I think they're fine. I get on one about once a week for something different...they are easy on knees and ankles. I know there are people that love them, but I like to get most of my activities outdoors.
Great job Kay, Cindy, Annisa, Nancy and Keri on the workouts, yoga, runs and snowshoeing. Keep it up guys.
