I can't say enough good things about this workout. It is definitely in the killer category, and it's fun, too! You alternate 3-1/2-minute intervals with recovery periods. The intervals start with regular step aerobics, and then you do super-intense plyos, jumps, and lunges. The recovery periods feel *so* wonderful! I won't pretend that I can get through all the intervals. The power scissors and plyo jacks are exceptionally hard. The plyo jacks seem to go on much too long -- I haven't timed that interval, but it seems much longer than the rest. Or is it just that I'm so winded and tired that it seems longer?

Even though the workout is killer, it goes by really fast. That must be because you're changing routines every 3-1/2 minutes.

The step aerobic segments consist of fairly basic choreography, but at a high-intermediate/advanced intensity level. They're easy to pick up. What amazes me is that in a "normal" tape, we'd probably consider these step segments to be a tough workout. But when you're doing this tape, the aerobics almost seem like rest, compared to the plyos and jumps!

A comparison to Intense Moves is inevitable, since up until now, that was the hardest interval tape available. I think they're both about equal in terms of toughness, with (maybe) Interval Max taking a slight lead. They're both fun, too, but I think Cathe's is more fun. That's not to say that I'll be giving up my Intense Moves, though, because I still love it. Plus, having two of them now will make burn-out less likely.

Can you guess my grade for this tape? A+++. I hope there will be more like this from Cathe!
