Still, it’s a worthy goal to lose belly fat because it’s “unfortunately the most dangerous location to store fat,” says Lawrence Cheskin, MD, chair of the department of nutrition and food studies at George Mason University and director of the Johns Hopkins Weight Management Center. Because belly fat—also known as visceral fat, or the deep abdominal fat that surrounds your organs—is more temporary, it circulates throughout the bloodstream more regularly and is therefore likelier to raise the amount of fat in your blood, increasing your blood sugar levels and putting you at a greater risk of heart disease and type 2 diabetes.
How to do a Turkish get-up: Holding one kettlebell by the handle with both hands, lie on your side in a fetal position. Roll onto your back and press the kettlebell up toward the ceiling with both hands until the weight is stable on one loaded side. Release your free arm and free leg to a 45-degree angle with your palm facing down. Slide the heel of the loaded side closer to your butt to firmly grip the floor.
Try this 4-minute rowing circuit: Begin with 20 seconds of rowing followed by 10 seconds of rest. Look at how many meters you traveled in that time. (Don't get off the rowing machine or even let go of the handle when you rest, says Penfold.) Repeat this eight times, trying to beat your distance each time. When you're finished with this four-minute circuit, row a fast 500 meters and note how long it takes you. "That's the number you'll want to match or beat during your next rowing session," says Penfold.
