A totally low-impact program that uses gliding discs and dumbbells to supercharge the aerobic intensity. It's short but tough — Cathe's non-stop, never-slow-down pacing is guaranteed to keep you burning fat for the entire workout. You get eight complete "cardio supersets." Each superset has two different exercises — an all-cardio series alternated with a cardio/toning sequence (e.g. pure aerobic gliding combined with a "traveling plank with push-ups" aero/tone interval). All the moves are easy on your joints; they range from kickboxing and cross-country skiing to "prisoner squats" and leg adductions (using the discs for sliding resistance). DVD also includes a "bonus" step-aerobics/dumbbell-toning interval segment (21 minutes). Requires 2 to 10 lb. dumbbells and gliding discs (paper plates will work). ©2011.
