This workout was released 13 years ago, and I started doing it probably 5 years ago, and while it may look a bit dated, the workout certainly isn't. This one WILL kick your butt. Even one of the background exercisers looks like she's going to keel over during the hi/lo section, which IMO is much harder than the step section. I still go back to this one when I need a serious cardio challenge.

Instructor Comments:
Cathe is completely in her element - I can't even imagine being able to talk during long portions of this routine and she's able to yell out instructions, etc without a hint of shortness of breath. She is amazing!
