It worked very well! I was VERY pleased with my results. Although I started out doing the entire circuit some days I didn't have the time though. I lost around 20 lbs in the course of 2 months doing it!! The best part was that all my body parts were really toned out. I think thats why I didn't lose as much weight as I was thinking I would (my goal was 30) however I was able to slip back into a size 5 no problem! Oh and my booty looked very nice.
