Actually, that's been going really well. I was doing the 15 minutes OnDemand workout. I did it usually 2-3 times a week (there was one week where i was sick and didn't really do much of it). I liked it so much that I went to B&N (where I had a gift certificate) and bought Cardio Pilates on DVD. Ouch. There's a big difference between the 15 min version that Comcast has up and the full 42 min + workout on the DVD. I didn't even finish it the first time I tried it. But today I got all the way through it.
Now to calm my muscles in the shower.
Edit: Dear Goddess, I love that mist setting on the showerhead!!
