Cardio Supersets
The dumbbells are used during the cardio part of the workout. This workout mixes metabolic training with high intensity intervals in numerous supersets throughout the routine.
The benefits of metabolic training are many – but make no bones about it. It’s a tough workout. When you finish, you’ll be sweating and breathless, but that’s a sign that you’ve tapped into anaerobic sources of fuel, and your body will have to work harder to recover. You’ll be burning extra fat and calories for hours after you finish working out.
