Jillian Michaels' Hard Body

Two aero/tone interval workouts that feature an immense variety of multi-muscle exercises. Jillian keeps you challenged with a non-stop series of endlessly-changing combos (a new routine every 30 seconds!). The cardio is mostly high impact — moves like “flying jacks” and “half-turn squat jumps.” The toning is equally tough — exercises like “pivot lunges” and “lateral moving push-ups.” Each program uses different moves in a similar format. You'll do six aerobics-and-toning circuits, then you'll repeat the series a second time. The sequences combine proven favorites with Jillian-specific variations (e.g. a straight-leg sit-up that's intensified with a rolling superman lift). Very smooth transitions. Requires 3 to 10 lb. dumbbells. ©2012.
