I tried the DVD for the first time 3 days ago. I have spent the last 3 days in pain. I knew I was sweating and achy by the time I finished the level 1 workout but didn't realise until I woke up the next morning, quite how much it worked. The muscles in my stomach, legs, and back have been so sore. I aimed to do this every day but have been too achy to do so. Even getting up off the sofa hurts. Hopefully the more I get used to exercise, the less it will hurt? Anyone else doing this DVD?
