Getting Into the Swing of Kettlebells

Getting Into the Swing of Kettlebells

by Berkeley Wellness  |  

If you belong to a gym or health club, you may have won­dered about those cast-­iron or steel balls called kettlebells, which look like small cannonballs with a thick metal looped handle on top. Or you may have seen them for sale in a sporting­-goods store. Why would someone want to work out with them in­stead of free weights or a medicine ball?

First used in the 18th century and still used to train athletes in Rus­sia and Eastern Europe, kettlebells are becoming popular here. They weigh anywhere from four to 75 pounds or more, vary in diameter and are very compact.

For most exercises, you lift just one kettlebell; for others you hold one in each hand. Standard exercises include the deadlift, single-­ or double-­arm swing, single­-arm row and shoulder press.

Kettlebells can give you a more dynamic workout than regular hand weights, resistance machines or medicine balls because, besides lifting them, you also swing them, which works more muscle groups, especially your “core” muscles. Studies have shown that such workouts not only build mus­cle strength and endurance, but also improve coordi­nation and balance.

And if you use lighter weights, work up to faster movements and don’t rest for long between exercises, you can also get a cardiovascular workout. Depending on which exercises you do and how intensely, kettlebell workouts can be very demanding and burn as many calories as using an elliptical trainer or stationary bike.

According to enthusiasts, kettlebells can replace all your other exercise equipment and workouts and produce twice the results in half the time. That’s overselling them.

Not So Fast

“Dynamic” workouts sound great, but moving a weight multidirec­tionally is harder and riskier than just lifting it up and down or having your movements guided by resistance machines at the gym.

It’s best to start out by taking a class or working with an experienced trainer to learn how to use kettlebells properly. Many DVDs, websites and You­Tube videos demonstrate workouts.

The key is to start out slowly with light weights to get a feel for the movements and swing the kettlebells in a controlled manner. Swinging kettlebells incorrectly or too strenuously can tear a mus­cle, tendon or ligament, or cause a neck or back injury.

If you have had an injury or have any biomechanical problem, talk to your doctor or a physical therapist before using kettlebells (or any other exercise device). And if you use them for fast­-paced workouts, make sure you’re fit enough for intense cardiovascular exercise.

Bottom Line: Kettlebells can be a good addition to your strength­-training and aerobics workouts, once you learn how to han­dle them.
