a friend at work got the "lift weights to lose weight" from kathy smith double dvd and said it was pretty good. she didn't know who cathe was so I showed her the show on fit tv - we always share fit tips and news so she said this was a good one to get- I was just wondering if anyone in here tried it and how they would compare it to a cathe workout. I always work out with cathe now but I also think it's good to vary things now and again- I just want to put my money into cathe videos first..any thoughts????
