I did Cardio Kicks yesterday and I did Circuit Max just last week. I really like both these workouts and still find them in my DVD player quite often. Cathe seems pumped and ready to work in both workouts!
Cardio Kicks has more of a hi-lo/kickbox feel than KP&C or Kick Max but it is fun and I am always looking for non-step cardio workouts.
Circuit Max I like because it can be done 3 ways. Cathe and crew do 5 min. of cardio then they do 2 min. of compound exercises using 5 or 8 lb dumbbells (like plie squats while doing shoulder presses, etc). You can do the workout just as Cathe does the workout, or you can tweak it to your own liking. For instance, while Cathe and crew do the compound moves, you can use heavier weights and eliminate the lower body work so that instead of doing a lunge with a bicep curl, you do only bicep curls, making it an upper body circuit workout. Or - you can eliminate the upper body work and use heavier weights and just do the lower body work. This is personally my favorite way to do Circuit Max.
