Grab a kettlebell and swing for the second move.

The kettlebell swing is an explosive cardio exercise works the big, powerful muscles around your glutes and quads, and sends your heart into overdrive, according to research from the University of Wisconsin. In the study, participants burned 20.2 calories a minute and their average heart rate was 93% of its max for the course of a 20-minute workout.

Place a kettlebell a couple of feet in front of you. Stand with your feet slightly wider than shoulder-width apart and bend your knees to lean forward and grab the handle with both hands. With your back flat, engage your lats to pull the weight between your legs (be careful with how deep you swing) then drive your hips forward and explosively pull the kettlebell up to shoulder height with your arms straight in front of you. Return to the start position and repeat without pauses.
