Query: Not that great

I don't think these dvd's are that great. I'm not sure if I just don't like Mari Winsor, or if I don't like pilates, but I bought these dvd's and only used them a few times before I lost interest. Some of the moves aren't that easy and others don't seem to do anything at all. I plan to stick with TaiBo.
