Cathe Friedrich's Circuit Blast DVD

An ultra-challenging workout that combines intense cardio with equally intense toning. It's a combo that's guaranteed to burn tons of calories and build super-strength (if you can keep up ... and survive!). You get six “rounds,” each with four different exercises.

The next segment integrates a toning element into the cardio (e.g. a “fire walker” — non-stop aerobics with a resistance band around your legs). That's followed by a fast-paced, multi-muscle body-sculpting series. It all ends with a tough core toning segment. Then you start the next round....
