Actually, the High Step TRAINING is an advanced workout (it's clearly marked as advanced, and I think this label is accurate), and, it's really a good workout. The High Step CIRCUIT, however is beginning/intermediate, an I find it too easy for advanced work. These are both part of the most recent series, and the closeness in their titles can easily lead to confusion (and disappointment). High Step TRAINING includes five challenging cycles, each with a cardio blast, leg presses, and weight work. It reminds me a little of a mix between Muscle Endurance and Boot Camp. The only complaint I have is that it doesn't have ab work, Cathe states that many of the exercizes do work the core however. High Step CIRCUIT has five fairly interesting cycles, they just move slowly, have fewer reps. You can, however, make your step higher, add more weight, etc. If you're looking for advanced, get the High Step Training.
