The first time I got on the elliptical in 2008, I'm not sure I lasted 2 minutes. I kept doing it, and loved it. The only reason I ended my workout was that I was bored. Silly, I know. Then I made friends with the bike. I really need the treadmill, though, for balance and bone density.

I don't know that this is just me, but...
I used to not do things for a week or so (if I'm sick, lazy, or just away somewhere), and there wasn't much change when I went back to using muscles. Now, it seems like I start to go to hell if I miss a couple days. I don't maintain like I did.
