I have the Kickboxing and Bootcamp workouts. They are great! Takes a couple of times doing the workout to get the moves down, but if you go through the tutorial it makes it much easier. Kelly will tell you what she is going to do, and then in the right corner there is a little window that pops up that demo's what she is talking about. Some combos can be a bit confusing. For the kickboxing I am able to use weighted gloves, for a more intense workout. Her Bootcamp is very similar to Cathe's 4DS Bootcamp, but you get two 30 min. workouts plus premix combinations. I plan on getting her other three workouts at some point.
