This is one of those sweat-dripping, endorphin-giving workouts. You won't even realize you've worked out for 27 minutes! In the first half we use dumbbells for strength, then we elevate our cardiovascular endurance in the second half. We finish this workout with core and mobility.

Equipment Needs: New to working out? You need 5 lb and 8 lb dumbbells. Been working out for awhile? Grab your light, medium and heavy dumbbells.
