Though marked by fitness queen Kathy Smith's perpetual cheeriness, Timesaver Cardio Fatburner is just what many busy exercise buffs need. Broken down into two 20-minute portions, this video offers a beginning lesson followed by a more complicated version. Anyone who has ever taken a cardio class will recognize the part dance, part aerobic moves. For the absolute neophyte, the steps get easier with each viewing. The sets are each self-contained allowing the student to do only one or both. Either way, the routines can be pumped up a bit for maximum workout. For the easily irritated, Smith's constantly vocal companions might be a distraction. But, for just 20 minutes out of the day, Kathy Smith delivers a nicely packaged deal. ~ Sarah Ing, Rovi
