I love all of Cathe's DVDs and have been using them for years. I just wish she would realize that not many of us have a lot of workout space. It would be great to have a step aerobics DVD that does not require an additional 7 to 8 feet. She has already indicated in the new series 4-day split that you will need a lot of space. Please Cathe remember that most of us have limited space and could you please make a DVD that would just be in the area around the step and not require an additional 7-8 feet. Also could you consider doing a DVD that does not require a step. I would love to just do a floor routine for once. The old knees are not what they used to be. I know Cathe gets a lot of suggestions and you can't please everyone. But there are a lot of us who are not so young and could use a floor routine that would be easier on our joints. Plus please try and remember to do a routine that does not require a lot of room. Most of us do not have a studio to workout in. Just your basic basement, rec room or living room. With all the furniture and stuff things just get in the way. So hopefully Cathe you are listening and can think of those who have knee problems and lack of space to workout in. Otherwise, Cathe you are doing a great job and I love doing your workouts and will continue to buy your DVDs as they come out. Love shaking things up a bit and changing the workouts I do. Thanks for listening.
