Three lower-body-focused aero/tone interval workouts. Each one gets progressively more challenging so you can smoothly advance to the next level as you get stronger. The cardio segments are non-stop fat-burners; they include high-impact moves like "star jumps," "scissor lunges" and "power jacks." The toning segments are equally intense; they feature classic buns/thighs exercises like squats, hydrants and side lunges. All the workouts are short, but exceptionally varied -- you get 8 to 10 different exercises in each circuit (plus within-circuit level modifications and even some "bonus" balance moves). As always, Jillian's cuing is both clear and relentlessly motivating ("I want your quads to be burning!") Requires 5 to 10 lb. dumbbells. ©2011 Level 1 Workout: Workout: 37.5 minutes (cardio-toning intervals) Cool-down: 3 minutes (stretch) Total Workout Time: 40.5 minutes Level 2 Workout: Workout: 38 minutes (cardio-toning intervals) Cool-down: 4.5 minutes (stretch) Total Workout Time: 42.5 minutes Level 3 Workout Workout: 36 minutes (cardio-toning intervals) Cool-down: 7.5 minutes (stretch) Total Workout Time: 43.5 minutes Chapters: Workouts Level 1 Level 2 Level 3 Workout Recommendations Set Up More From Jillian Do the saddlebags on your legs make you insane?
