I lost 25 lbs and got muscle tone from this workout and no I'm not some advertising person. If you are like me and start out not being in the best shape just do the best you can, don't expect to come out doing things as fast and smooth as Billy Blanks. I lost a couple DVDs to this so I plan to order another set now that I have baby weight to lose. My husband is in the military, he said this workout made him break a sweat but didn't feel it in his muscles, so my advice is if you are already in ready great, toned shape, this workout will feel more like just a cardio and may not be worth it for you. If you need to get started somewhere and want results, this is for you. After I did this program for 4 months the first time, I had confidence to workout in a gym. I know its worked before so it will again. Follow the workout schedule too. Enjoy!
