The 6 Best Adjustable Kettlebells for Your Home Gym

Our guide is competitive. Many iconic brands produce adjustable kettlebells with rave reviews and similar specs. What puts REP’s adjustable kettlebell in our Best Overall spot is that it looks, feels, and performs most like a standard kettlebell—even the handle diameter is nearly competition-grade—and the price is very fair for the equipment you’re getting.

Like nearly everything REP produces, this kettlebell sets the standard for quality. The frame is cast iron and powder-coated to improve grip. The traditional shape lets kettlebell athletes use it, so their training transfers to competition. Even the bottom of the kettlebell is covered in rubber to protect your floor—a minor detail we appreciate. Typically, you’re paying above market for this level of quality and design, but REP’s adjustable kettlebell is less expensive than other picks here.

REP offers three different weight ranges: 8-16kg (17-35lbs), 16-24kg (35-53lbs), and 10-40lbs. The kilogram kettlebells adjust in two-kilogram increments, and the pound kettlebells adjust in five-pound increments. To select your weight, turn the dial on top of the kettlebell (below the handle). Then lift the kettlebell off the weight stack, where the remaining plates will sit for the duration of your set or workout.

If you want to nitpick, other brands have said that the plastic dial feels cheap and prone to breaking. We want to highlight this detail, but our editors don’t think this is an issue unless you plan on abusing the kettlebell.

No matter which weight range you choose, you’re replacing five kettlebells. For general fitness enthusiasts, we like the 10- 40 lb option; it’s enough weight to challenge you for presses and high-rep sets of squats and rows. If you have some lifting experience and want to primarily train explosive movements like swings and snatches, as you traditionally do with kettlebells, opt for the 16-24 kg range. Unless you’re a complete beginner, we suggest those two weight ranges.

Bells of Steel created something very cool with this competition-spec adjustable kettlebell. The weight range and increments are fantastic, and the dimensions match competition specs exactly. You’ll replace 18 kettlebells for less than $300. Two reasons it’s not our overall best pick are that the adjustment process is comparatively time-consuming, and a competition-style bell isn’t for everyone.

To change the weights of the Bells of Steel kettlebell, you need a few minutes and a couple of tools. Use an Allen wrench to undo the bolt on the bottom of the kettlebell, remove the bottom half, then loosen the other screw that secures the plates with a traditional wrench. You can then add more plates in half-kilogram increments to the bolt that runs through the top half of the shell. Because the adjustment process is more time-consuming, this isn’t the best kettlebell for circuits or workouts that demand you change weights on the fly.

At first glance, you probably can’t even tell this is an adjustable kettlebell; it has a smooth cast-iron finish, no dials or switches, and a 35-millimeter handle that looks identical to standard competition kettlebells. This adjustable kettlebell is for serious kettlebell athletes. That said, if you’ve never trained with an adjustable kettlebell, be aware that the stainless steel handle can rub the hand raw (use a lot of chalk), it’ll feel more cumbersome than other picks in our guide, and the starting weight is over 24 pounds.

This is a solid choice if you’re a kettlebell athlete or want a heavier adjustable kettlebell (and you’re okay with the adjustment process).

From the company that brought adjustable dumbbells into the mainstream, BowFlex’s SelectTech 840 adjustable kettlebell is a great entry-level model for the kettlebell-curious gym-goer. It’s reasonably priced, replaces six kettlebells, and adjusts easily on the fly. The SelectTech 840 offers six different weights: Eight, 12, 20, 25, 35, and 40 pounds, enough weight to challenge you during isolation movements like curls and extensions while providing enough resistance for snatches, cleans, and rows.

If you’ve been training with kettlebells for a few years, 40 pounds will likely be too light, so you’ll want a kettlebell with a heavier top-end weight or consider buying two of this model. While it isn’t shaped exactly like a kettlebell, it feels enough like one that anyone who uses a traditional kettlebell won’t be completely thrown off. The dial on top of the kettlebell makes adjusting between weights a breeze, and the wide handle makes two-handed exercises easier.

I don’t love the plastic shell, which leaves the SelectTech 840 more prone to breaking if dropped. Also, the smooth handle makes it harder to hold onto the bell, especially after you’ve worked up a sweat. Overall, this is a basic, easy-to-use kettlebell with a moderately challenging weight range. If you’re a beginner or casual kettlebell user, you’ll enjoy BowFlex’s adjustable kettlebell.

Powerblock is best known for its rectangular adjustable dumbbells, which can hold up to 100 pounds, but the brand also makes a rugged, compact adjustable kettlebell with a decent weight range.

The 18- to 35-pound kettlebell measures 5.75″ L x 4.25″ W x 10″ H, while the 35-to-62-pound kettlebell measures 8″ L x 5.5″ W x 11.25″ H. That’s not drastically smaller than other kettlebells in our guide—in fact, Titan’s adjustable kettlebell is half an inch shorter than Powerblock’s heavier kettlebell—but its size relative to the weight range earned it the superlative of most compact.

We like a few things about this kettlebell. First, the handle is wider than most single-weight and adjustable kettlebells, which I like for two-handed movements like swings and upright rows. This kettlebell is also made from steel and feels sturdy and durable. You can drop it without worrying it will break; there aren’t any plastic parts. Lastly, the untraditional shape may throw off some kettlebell enthusiasts, but I think the sloped sides make it sit more comfortably on my wrist. Anyone who snatched or cleaned a traditional kettlebell knows the pressure that can be put on the wrist.

Unfortunately, you have to choose between a lighter or heavier kettlebell. Each model replaces just four kettlebells, less than any other pick here. With either kettlebell, you’ll get the shell plus three weights you can select with a pin. (FYI: You need the pin to choose the weights, and Powerblock doesn’t seem to sell a replacement part.) Sixty-two pounds is a substantial top-end weight for an adjustable kettlebell, and only the Titan Loadable Kettlebell Swing and Bells of Steel Competition Kettlebell offer a heavier option.

We picked Titan as the best budget option because, for this price, the equivalent of seven kettlebells is a pretty damn good deal. It looks and (mostly) feels like a traditional kettlebell, is compact, and uses cast-iron plates, which adds to the product’s durability. What we like most about Titan’s kettlebell is its price and shape. Regarding gym equipment, this is pretty affordable for almost any product. A 40-pound kettlebell from Titan Fitness is no small cost, so add six more kettlebells to your cart; it is worth it.

The shape and size are comparable to traditional kettlebells, so you shouldn’t have a hard time adjusting your technique if you switch to this model. This kettlebell starts at 10 pounds and goes up to 40 pounds, a good weight range for beginners and intermediate lifters. The weight is light enough to master movements like the snatch, clean, and jerk and to burn out the muscles during exercises like curls and overhead presses.

Unfortunately, 40 pounds isn’t enough weight for stronger individuals to get much out of movements like kettlebell swings, rows, chest presses, and deadlifts. If you want to do high-rep workouts with intensity, you can still use this bell. However, expect to outgrow this weight range at some point.

The weights on this kettlebell aren’t marked, so you need to read the plates on the inside to figure out how much you’re lifting. Ideally, Titan would paint the numbers somewhere on this kettlebell. Also, adjusting Titan’s kettlebell isn’t as easy as most other picks we’ve tested. You need to unlock the plates and then slide them out one at a time. But these are little nuisances in the grander scheme of what you’re getting for the price.

We’ll admit that this is more of a kettlebell-adjacent tool, but we’re including it because it’s affordable, you can load it up to 500 pounds, it uses weight plates, and you can use it in a few creative ways.

First, let’s be clear: Titan’s loadable handle is not a kettlebell replacement. It’s nowhere near the size of a standard kettlebell, so you can’t perform classic kettlebell movements like the snatch, clean, and jerk. As the name implies, Titan’s Loadable Kettlebell Swing is for swinging, with the main benefit being that you can load it with hundreds of pounds.

Swinging this handle will not feel like swinging a kettlebell. It’s 19 inches tall, eight inches taller than a competition kettlebell. You’ll probably feel unstable and unbalanced the first few times you swing it, since the plates are relatively far from your center of gravity. You’ll also need to assume a wider stance than you do with standard kettlebells. A competition kettlebell is 8.25 inches wide. By comparison, some metal 45-pound plates are nearly 17 inches across, and 25-pound plates are almost 12 inches across. We suggest loading 5-, 10-, and 25-pound plates onto the handle so you don’t have to widen your stance.

Even though you can’t technically replace a kettlebell with this handle, it’s still a valuable and fun addition to any home gym. Aside from heavy swings, you can perform one-arm rows, upright rows, single-arm farmer’s carries, duck walks, and elevated sumo deadlifts with this handle. We say “addition” to a home gym because this handle is an excellent buy if you own weight plates. Otherwise, you’ll need to shell out extra money for plates to load it.

If you’re looking for a pure kettlebell replacement, Titan’s Loadable Kettlebell Swing is not for you. However, with a $50 price tag and a 500-pound weight capacity, we think serious strength athletes will love this unique tool for heavy swings, rows, elevated deadlifts, and carries.
