4-Minute Heart-Pumping Tabata for Belly Fat

The belly fat that matters most wraps your organs, not your waistband. This World Heart Day, spend 4 minutes on a Tabata under Fat burning: 20 seconds all-out, 10 seconds of rest, 8 rounds. Those short rounds get your heart rate up and keep you burning after you stop. Stack a few days and the effort adds up!
