A genuinely challenging program that combines gliding-disc cardio with multi-muscle body-sculpting. No jumps or hops, this workout burns fat and sculpts your body without stressing your knees or back. The aerobic segments are tough — Cathe blends fast-paced, low-to-the-ground movements with lots of repetition (while utilizing the gliding discs to maximize the range of motion). The toning segments feature a balanced mix of compound exercises; they work your body in all three planes: front, back and side-to-side (many of these moves use the discs too). Cathe also includes some innovative exercises like "air squats" and "Dixie cup lunges." Requires 3 to 10 lb. dumbbells and gliding discs (paper plates will work). ©2011.
