Query: LOVE THIS!!!

I have quickly become a "FAN" of Susan Chung's DVD's. I have purchased Rapid Fire and Rapid Fire 3. I recently purchased this one because I wanted a 90 minute workout that had a variety of segments. This workout is so much fun, that I couldn't believe how quickly the time went. Susan's moves are not too complex and the core segment is excellent. I burned 540 calories doing the full 94 minutes! If you enjoy Kickboxing and are looking for a long workout, that is fun and you have the time to do it (recommend doing so on a day you don't have to work), then go for it! You won't regret the purchase...!
