I managed to do a Cindy Crawford DVD last night, and hopefully will make it to the gym tonight if hubby gets out of work in time. The Cindy DVDs are interval training with weights etc. They don't make me break a sweat, but they are really good for toning and building muscle. I can remember the first time I ever did one -must have been at least 10 years ago - I thought they were really hard, and I ached all over whereas now I could do them in my sleep...
