mb2004 - Aww, thanks! It's a ring sling. I love it, but it only works when the babes are super tiny. After about 12 pounds or so I have to switch to the ergo because the sling hurts my back. As for your off days, maybe consider getting a cheap bike off craigslist or something? Or just hit the weights.
xRiotGirl - Hey, you look familiar! Glad to see you over here.
KarinRose - Don't be scared! I was really worried about week 5, but it was, amazingly, no big deal. I mean, it was hard and all, but the program really works and by the time you get there you'll be able to handle it.
magicsusan - Yeah, exactly. This is teaching me how to really be disciplined to make myself do stuff even when I don't feel like it. I'm learning that I really can just make my legs keep moving even when I'm tired.
