Manufacturer: CAP Barbell | Weight Range: 10 – 80 Pounds | Interior: Cast Iron | Exterior: Enamel Paint | Price: 💰💰💰

CAP Barbell makes a broad range of quality workout equipment, and the same is true for their kettlebells. With twelve different sizes ranging from 10 pounds to 80 pounds, there’s an option here for every body.

Constructed from solid cast iron with no weld or seams, you can be sure of these kettlebells’ overall quality. They also come with wide handles, making it easy to grip with one or two hands (essential for programs like CrossFit). Simply take hold, and begin your routine full of swings, deadlifts, snatches, and more — the CAP Barbell is built to handle it all.

Like other CAP equipment, burrs are relatively commonplace when using this kettlebell consistently. Just be sure to take good care of it, and the CAP Kettlebell is guaranteed to return the favor.

The best kettlebells on a budget

Best Choice HDPE Kettlebells

Manufacturer: Best Choice | Weight Range: 5 – 15 Pounds | Interior: Cement | Exterior: HDPE | Price: 💰💰💰

Where can you get a set of three kettlebells for the same price as a monthly gym membership? From Best Choice, of course!

Staying true to their mission of creating affordable workout equipment for everyone, Best Choice’s kettlebell set is perfect for folks on a budget. You get three kettlebells total: one 5-pound, one 10-pound, and one 15-pound. Together, these are perfect for newcomers and casual lifters seeking to gain strength over time.

The price is so low because they’re made of HDPE (High-density polyethylene) and filled with cement. But this shouldn’t be a concern for lightweight and moderate-intensity workouts, as the exterior is plenty durable. They’re also exceedingly ergonomic thanks to wide handles, and the set even comes with a convenient rack for storing them away after use. Without a doubt, some of the best cheap kettlebells on the market.

  • Wide ergonomic handles
  • Among the best kettlebells for the money
  • Comes with a storage rack for all three kettlebells

There’s no doubt about it. The SPRI Vinyl Kettlebell Weights are the best kettlebells for beginners.

No matter which size you choose, the SPRI Kettlebell offers a range of essential elements for newcomers: a quality, ergonomic design, a range of weight options, and a safety-oriented vinyl coating. This last part provides comfort and ensures slightly less damage to your home or body, should it swing into any, er, unwelcome areas.

Unlike buying a complete set, you’ll have to shell out a bit of money on each kettlebell individually. But they’re all reasonably priced and look so great together, with their shiny vinyl coatings all in a row. With ten weight variants to choose from, you can’t go wrong choosing SPRI.

  • Reasonably priced by weight
  • Fantastic overall craftsmanship
  • Weights are vinyl-coated and color-coded

  • Small handles
  • Noxious vinyl smell

The best competition kettlebells for serious athletes

Manufacturer: Ader Sporting Goods | Weight Range: 17 – 70 Pounds | Interior: Cast Steel | Exterior: Premium Paint | Price: 💰💰💰💰

If you’re competing and have the money to shell out for top-tier gear, the Ader Pro-Grade International series is the best fit for you.

The bells themselves are painted according to weight, and they’re all the same size. Made from high-end cast steel, these are the creme de la creme among kettlebell brands. The grips are wider than other brands, too, about 33 millimeters across. As for comfort? According to reviewers, the handle itself is sanded down to a perfectly smooth bare-metal finish, with the most ergonomic grip on the market.

Do remember that these are pro weights, with the lowest option starting at 8 kilograms or roughly 17 pounds. Bad for beginners, but perfect for professional athletes.

  • Extra-wide handles
  • Professional-grade cast steel
  • There’s a wide range of weights and colors

  • Extremely pricey
  • Some QC issues with the paint finish

5. Apex Adjustable Kettlebell

The best adjustable kettlebell

Apex Adjustable Kettlebell

Manufacturer: Apex | Weight Range: 20 – 50 Pounds | Interior: Cast Iron | Exterior: Powder Coating | Price: 💰💰💰

Just starting your kettlebell workout? Perhaps you’ve been on the grind and see your strength rapidly improving?

Either way, an adjustable kettlebell may be the perfect option for you. The Apex Adjustable starts around 20 pounds, and lets you add weight all the way up to 50 pounds. In other words, it supports your every stage of growth!

The Apex is made from heavy-duty cast iron that’s powder-coated for premium protection. It’s also equipped with a U-shaped handle that provides a superior grip and enough room to get both hands inside. 

The major downside of the Apex is that changing the weights is a major pain. There’s lots of finagling involved, and it’s not worth the hassle when you’re mid-workout. If you keep at the same weight during your entire routine, this shouldn’t pose much of a problem. Indeed, you’ll probably appreciate the secure assembly!

When all is said and done, the Apex Adjustable is one of the best kettlebells for women and men across the spectrum.

  • Adjustable weight from 20 to 50 pounds
  • Perfect for a range of workouts, from light cardio to weight training
  • No need to purchase multiple kettlebells — this one grows with you

What to Look for in the Best Kettlebells

Less than 5% of American adults are active for even 30 minutes every day. Whether you’re starting your own workout routine, or you’re already a committed fitness fan, adding kettlebells to your regimen will help to improve both your cardio and strength training.

Here’s what to look for when shopping for the best kettlebells.

1. Weight

The first thing to keep in mind is weight. The best kettlebell weights for you depends on your current strength and fitness level.

For beginners, we recommend around 15 to 20 pounds. This should provide a smooth transition as you learn your routines, get a feel for kettlebells, and build strength. For intermediate users, 35 pounds is an ideal starting point.

It also depends on your exercises. You don’t want to use the same weight for a one-arm swing as you do for a deadlift. If you plan to do a variety of exercises, consider buying a set of kettlebells. Remember: safety first!

2. Material

Kettlebells come in all different types of materials. The most common kettlebells feature metal interiors, with powder-coated or vinyl covered exteriors. There are many exceptions to this rule, however.

You’ll also find interiors made of cement, sand, or other low-cost, heavyweight materials. In terms of the exterior, many of the best kettlebell brands opt for painted or hammered finishes, which can be a nice change of pace.

While we typically recommend iron or steel kettlebells, that’s no guarantee of overall quality. Be sure to check out user reviews for a better understanding of craftsmanship. 

3. Durability

What do you do with kettlebells? You lift them, swing them around, and carry them all around your home gym (hopefully on a regular basis). That means it needs to be tough — like, ultra-tough.

Harkening back to materials, metal kettlebells are almost guaranteed to withstand a good beating. Another ideal option is a vinyl-covered model, which protects the bell and the gym, and provides an additional layer of safety. 

As with most things, the better the quality, the higher the cost. Do not make sacrifices on durability. If you must, save up a bit before buying and invest in a robust kettlebell that can handle your massive muscles.
