I am not a fan of circuit workouts (I am trying to get into them and have just purchased High Step Circuit), but I just used this Cardio Coach one and wow! I burned 360 calories in 39 minutes! Best of all, it got me back on my Eliptical trainer which I haven't used in 3+ years mostly because of the boredom factor... with this the time basically flew by!;-)
