Superbly cued, it's the toughest kickbox program ever. You get three distinct segments — do any segment for a targeted workout or all three for an “extreme challenge.” You'll start with a well-sequenced, well-choreographed cycle of classic kickboxing moves (e.g. jabs and punches, kicks and shuffles). That's followed by high-impact aerobic/anaerobic plyometrics (e.g. jumping jacks, air jacks, tuck jacks — Cathe seems to spend more time in the air than on the ground). Finally, you'll totally fatigue those tired leg muscles with a series of kickbox toning exercises. The DVD's “premix” feature also lets you do pre-selected, shorter versions of the workout. ©2005.
