Two Tabata workouts that alternate challenging cardio drills with dumbbell-enhanced strength training. Both programs offer the option of lighter weights/more reps or heavier weights/fewer reps. Like all Tabata workouts, each exercise is done at maximum intensity for 20 seconds followed by a 10-second “rest” interval — repeated eight times. The aerobic segments include lots of higher-impact jumps and hops (both on and off the step). The toning ranges from simple bench presses and single-arm rows to more diverse “fly/skull-crusher combos” and “double reverse flies” (many of these sections incorporate a step). A high-energy, techno-style soundtrack. Very clear, one-on-one cuing. Requires 3 to 15 lb. dumbbells. ©2013.
