What is a kettlebell workout?

Working out with a kettlebell, a type of weight that looks like a bowling ball with a handle, provides a unique weight training and cardio workout.

Hoisting the heavy metal bells not only helps strengthen your arms and pecs, but also works your core, heart and lungs. Kettlebells range from eight pounds to 100 pounds.

The reason the kettlebell is so great is that there’s an offset center of gravity.

That means your body has to work harder to maintain balance. In so doing, you work many different muscle groups -- and get your heart rate up at the same time.

Working out with kettlebells also increases core stability, and typically involves a circuit that gets your heart pumping while it strengthens muscles. Once you are properly trained, you can workout at home on weights that you can buy at an affordable price.
