Cathe Friedrich's XTrain: Cardio Leg Blast

Using both step and non-step exercises, you'll alternate plyo-style cardio with classic lower-body toning. It's a tough “12 round” workout that's guaranteed to burn mega-calories while building lean legs and a tight butt. The cardio segments are short but intense. They range from high-impact “air jacks,” “pop squats” and “power scissors,” to dumbbell and band-enhanced side lunges and “frog jumps.” The toning sections feature classic gym-style exercises like lunges, plié squats, deadlifts and step ups. While they're primarily lower-body focused, these toning routines often also include an arm-strengthening element. Requires 2 to 10 lb. dumbbells, a step and a loop band. ©2012.
