I have been doing the 30 day shred for a few weeks now and I do take a couple of days off (on the weekend) because I was killing my knees! Yesterday I did 5.1 miles of walking 3 miles on the exercise bike and the 30 day shred dvd and I felt great!!! Plan on doing it again tonight! I was at a stall until this morning and finally seen 1.5 pounds gone today. I have been walking 25 miles a week or more for a few weeks and last night was the first night I did the bike so maybe that got me out of the stall?? I hope anyways!
