If any of you advanced exercisers are looking for a good interval training tape - this is it! Gin leads you through a killer 50 minute, athletic (not dancy) step workout (warm up, 30 min interval training, cool down).

Karen P. did a great job of describing the workout, so I won't repeat it here. I would describe myself as an advanced exerciser, and have been doing interval track workouts regularly, and the hardest variation was incredibly tough to keep up with for the entire minute. This was quite an ego-smasher for me! Anyone who can complete this video with the hardest variation throughout is truly a cardio God. This actually reminded me of my track workouts, or my high-school basketball practices - the coach yelling at you to "push it, push it, push it", then, "good job" when you get through.

I know that a lot of people might be hesitant about the length of the tape, but you have to remember that this is an interval workout - throw that "an hour of aerobics are required to do any good" theory out the window. This tape will burn more calories than you ever have before, while dramatically increasing your aerobic capacity.

I think that it would be easy to grow with this tape. Even the base moves (the non-intensified version of the interval) are pretty intense (no basic steps here!), so starting off at that level and slowly increasing the intensity as you get more fit would work very well.

If you didn't like the style of the other Reebok step tapes, don't let that keep you away from this tape. The funky MTV set is gone, and Gin actually talks for real (which is damn impressive given that she does the hardest version throughout). The music is a cool instrumental, which I really liked.

Overall, this is definitely a Hall of Famer in my book. It's actually worth the price of the video to see Gin perform the workout - she is one heck of an athlete.

Gin does a fantastic job cueing in this tape. She constantly gives form pointers, and lets you know that you can drop down in intensity if you need to. I also liked the way that she keeps egging you on to push through the intervals - some of them are incredibly tough, and I really needed her prodding (come on - come on!) to keep going. She talked pretty much non-stop through the workout, but I actually liked it - it's not mindless chatter - she is doing a great job of leading you through the workout. She lets more of her personality show through in this tape, and you really like her. I felt as though she was my personal coach.
