Wanted to add my .02
Not that you asked, but here's my opinion:
I personally really, really like High Step Circuit. High Step Training Advanced is my all-time favorite high step workout, and I love High Step Challenge as well, but I sometimes think High Step Circuit gets overlooked as a good circuit workout. I'm an advanced exerciser (or was until the end of 2008 saw me get chubby and lazy!) In any event, here's what I do to make High Step Circuit tougher. Feel free to try any or all of these modifications to make it a more advanced workout:
-Cathe and crew use 6" for the step portions. Try using 8".
-The cardio portions last 1 min. As soon as the cardio is over, I hit the 'back' button on my DVD player and repeat the cardio. I'm pretty sure the workout still comes in under an hour when I do this.
-When Cathe does repeaters try doing power 3's.
-When Cathe does leg presses with no weights (while using a 10" step), I hold a heavy dumbbell and do them on a 14" step.
-During the other non-weighted leg segments (rear and side lunges, sculpting drill, running man), try holding light dumbbells or a medicine ball - or - don't use weight but up the height of your high step.
-Instead of using 3 lb dumbbells, use 8's or 10's or whatever weight challenges you.
-When Cathe uses the tubing, try to create as much tension with the tubing as possible. For some exercises, you can hold light dumbbells and the handles of the tubing, for added resistance.
- Hold a medicine ball or light dumbbell during some of the abs segments.
Also, I have done this workout on a BOSU and that has really upped the sweat factor.
I thoroughly enjoy this workout. I hope you do, too.
Cathe has several workouts that use only the high step (and not the club length step):
High Step Circuit
High Step Challenge
High Step Training Advanced
Push/Pull
Muscle Endurance
Legs & Glutes
Boot Camp
Pyramid Lower Body
Butts and Guts
Gym Style Legs
Pure Strength Legs & Abs
Pure Strength Back & Biceps
4-Day Split Kickboxing (the cardio segment uses no equipment, but the legs segment uses the high step)
4-Day Split Bootcamp (the cardio uses the club length step but the triceps and biceps segments use only the high step)
4-Day Split Lower Intensity Step (the cardio uses the club length step but the shoulders and calves segments use only the high step)
I think that's all of them - not 100% sure. In any event, I think the high step is a worthwhile investment, and I think you'll really enjoy Cathe's high step workouts!!!
