Hi Ellen! I've been on BodyRX now for 4 weeks in Cycle 1. Nutritionally its the best I've ever found. Finally a doctor telling you how to get in the right amount of protein, carbs and fiber into the course of the day. I have NO SUGAR cravings at all and I'm so full that I'm never hungry. I also have derived far more energy and power to my strength training. Its unbelieveable! As far as the exercising goes, I found the lifting to be far better for me. Going as heavy as you can w/excellent form for 3 sets. I think I'm going to see really good results by the time I get to the last cycle. Don't quite know yet how far up in weight I can go. I'm lifting far heavier than Cathe and that's what I wanted to achieve but couldn't do it w/her tapes because of the speed and the nature of the exercises. If you start this program, you will become a heavy hitter if this is what you want to achieve. My goals are to become more cut and to lower my body fat. Also I'm an advanced exerciser, not a novice of weight training so you have to decide for yourself. You can always follow along w/Cathe's strength tapes and follow the book for nutrition and yes this is something that I'll do for the rest of my life. Good luck! Kathy
