Kelly Coffey-Meyer intermixes higher-impact floor aerobics with interesting step combinations. From bounces, jumps and twists to jacks, pendulums and martial arts kicks, the variety and challenge never subside. Not a lot of repetition, each fast-paced, add-on routine builds to completion in just 5 to 6 minutes (then it's on to something new). The "intensity bursts" really raise your heart rate; they include wide-ranging lateral and low-to-the-floor moves plus some higher-impact plyometrics. The step segments feature a medley of creative patterns that use the bench both sideways and toward the TV. The workout ends with an ab-focused cooldown. Kelly's cueing and pacing is superb; she always seems to know exactly when to add a new move. This step workout is designed to get you fit using traditional step combos combined with intensity moves. This format takes you through all the moves needed to get great results with continued use.
