Whether you’re working out in a gym or in a small space at home, a kettlebell can make an efficient addition to your routine. Kettlebells are small, typically round free weights that come attached to a handle that you can use to grip the weight.

Whereas many free weights come in sets, kettlebells are designed to be used on their own, so they offer a particularly small space-friendly way to strength-train.

While you can use a kettlebell as a substitute for an array of other free weights (like dumbbells, medicine balls, and more), kettlebells lend themselves particularly well to quick, dynamic exercises. If you’re looking to change up your strength-training routine—or cut down on fitness equipment—a kettlebell can help you get there.

Here are the best kettlebells on the market to get you started.

Also nice? Rogue’s Competition Kettlebells are subtly color-coded, making it easy for you to keep track of your weights (even if you stock up on a few).

What to Look for in a Kettlebell

Weight

Kettlebells should be heavy enough to pose a challenge, but not so heavy that you’ll struggle to maintain proper form. Pay attention to the weight of the kettlebell you’re eyeing. And if it’s an adjustable kettlebell, pay attention to the weight range, instead.

Material

Most kettlebells are made from cast iron or cement, but their exteriors can vary significantly. Adjustable kettlebells may be finished in plastic, and floor-friendly kettlebells may be coated with vinyl or rubber. Keep in mind where you plan to use your kettlebell, and make sure the material suits your use case. (A solid cast iron kettlebell with no coating might scratch your hardwoods, for example.)

Grip

In order to get the most out of your kettlebell, you need to be able to hold it. So you’ll want to pay attention to a handle’s size, shape, and texture. Wide, flat handles tend to give your hands more room than small, round ones. And textured handles tend to be easier to grip than smooth ones.

FAQs


What is the best weight to start with kettlebells?

When it comes to any kind of strength-training, you want to use a weight that will challenge you—without causing you to sacrifice your form. This starting point will vary from person to person. (Some of us can lift more weight than others.)

Consider the weight you can handle in other strength-training exercises, and try starting there. “If your form starts to break down, you need to drop the weight,” said Joel Okaah, CPT and field support specialist at D1 Training. You’ll know you’re on the right track when you can perform several reps with perfect form, without feeling entirely worn out, Okaah adds.

What is the best kettlebell exercise?

It may sound like a copout, but there’s no one best kettlebell exercise. But there are several really great ones that will help you train efficiently. Okaah recommends kettlebell swings (an intermediate exercise that can elevate your heart rate, and strengthen your lower body and core), Romanian deadlifts (an intermediate exercise that can strengthen your lower body and core), and goblet squats (a beginner-friendly total-body exercise). 

But other classic kettlebell exercises, like kettlebell cleans (an intermediate upper-body exercise), kettlebell presses (an intermediate full-body exercise), and kettlebell snatches (an advanced full-body exercise) can also make great additions to your routine.

Why are kettlebells so effective?

Kettlebells are great because you can use them with slower, more controlled exercises and also with faster, more dynamic ones. This makes the kettlebell a particularly versatile piece of fitness equipment. “Kettlebells are a game-changer because you are able to perform a variety of dynamic movements with just one piece of equipment,” Okaah says, adding that you can use the weight to work a range of different muscles, depending on what exercises you’re doing.
