Kettlebell Workouts

Kettlebells aren't just for hardcore bodybuilders, and the enthusiasm for them is backed by medical research. A study from the American Council on Exercise concludes that a 20-minute workout with a kettlebell can burn the caloric equivalent of running at a six-minute mile pace.

Try the following moves to get started. All you need is a single kettlebell and an exercise mat.

Grasp the kettlebell in both hands. Assume a squatting position, with your legs hip distance apart, your back straight, and your knees bent at a 90-degree angle. Hold the kettlebell between your legs. Straighten, stand, and swing the kettlebell outwards until it is at eye level. Contract your thighs. Return to the starting position. Do 10 to 15 repetitions.

Stand up straight with your knees slightly bent, feet hip-distance apart. Grasp the kettlebell in both hands. Raise it over your head, then swing it in a clockwise motion around your head. Repeat 10 to 15 times, then swing the kettlebell in the opposite direction.

Stand upright with your feet hip-distance apart and your feet turned outward 45 degrees. Grasp the kettlebell with both hands in front of you. Bend your knees, keeping your back straight, and place the kettlebell on the floor. Then stand and lift the weight up to chest height, your arms parallel to the floor. Grasp the sides of the handle and lift the kettlebell straight over your head. Lower the weight back down to your chest and return your hands to their original position on the top of the handle. Do 10 to 15 repetitions.

Lie down on your back with your legs straight. Hold the kettlebell in one hand with your arm extended in a straight line from your shoulder. Bend the opposite knee, prop yourself up with your other arm, and slowly rise off the floor, balancing the weight carefully above your shoulder. Stand, and reverse the movement to return to your starting position. Do five repetitions on each side.

Ready to torch those calories in a whole new way? While kettlebells provide stimulating exercise, don't get overeager. The challenge of a kettlebell can also be dangerous. Kettlebells offer a lot of bang for your fitness buck, but the reason they're effective is because they work your core and offset your balance in unexpected ways as you swing the weight around. That unsteady element means you risk injury if you aren't careful. Working out with a kettlebell can be more rewarding and more effective than using regular dumbbells, but the chance of pulling or spraining a muscle is greater.

If you've never used a kettlebell before, author of Kettlebells for DummiesSarah Lurie recommends starting with a lighter weight than you'd use for dumbbells. If you normally lift 8- to 10-pound weights, start with a 15-pound kettlebell.

Stand with good posture throughout your workout to prevent injury to your core. Maintain a natural S-curve in your spine to distribute the weight of the kettlebell correctly. Focus straight ahead, and keep your head and neck aligned with the rest of your spine.

If you're a beginner with the kettlebell, don't try to do too much at once. A short routine or circuit is more than enough. Since kettlebell exercises are so efficient at burning calories, you'll still be getting the level of workout you crave. Put together the kettlebell exercises above into a simple circuit, moving through each exercise one right after the other. Repeat the circuit two or three times. If you need more than that, repeat the circuit again, or do more reps in each circuit until you're ready to move on to a more advanced workout program.

When you're ready to move from a beginner's workout to a more advanced routine, consider outside resources such as kettlebell classes, personal trainers, DVDs, and books to guide you in building a more advanced workout while mastering proper technique and form. Kettlebell resources include books like Russian fitness instructor Pavel Tsatsouline's Enter the Kettlebell or the more advanced Return of the Kettlebell. Also consider DVD programs, such as Phil Ross's Power Body: Advanced Russian Kettlebell.

If you're looking to kick your workout a few notches or find your way out of a fitness rut, a relatively simple set of kettlebell routines can lead to fast results and increased cardiovascular fitness. Remember to warm up and cool down with stretches before and after your workout. The kettlebell will challenge your muscles and core in new ways, so preventing injury and speeding recovery is key to an enjoyable workout.
