10 Best Adjustable Kettlebells 2025 in the United States

The Kettlebell Kings Adjustable Kettlebell Set offers a versatile weight range from 26 to 71 lbs, making it suitable for a wide range of strength levels and exercises. Its weight adjustment uses a straightforward 7-plate design secured by an Allen wrench, which allows for smooth changes but might slow you down if you want to switch weights quickly during a workout. Made from durable alloy steel with a powder-coated finish, this kettlebell is built to withstand regular use without fading or damage. The 1.4-inch (35mm) handle is designed to provide a comfortable, firm grip for most users, whether you prefer using chalk or not, which is important for safety and control during lifts.

Its size is compact enough for home use yet substantial to deliver proper training stimulus. The lilac purple color adds a unique touch compared to more traditional kettlebell looks, which might appeal to those wanting something stylish. One helpful bonus is the included instructional resources to help users get the most from their workouts, especially if you're newer to kettlebells. On the downside, the reliance on an Allen wrench for weight changes means it's not ideal if you need rapid adjustments between sets. Also, while the handle diameter suits most hands, those with very large or small hands might find it less comfortable.

This adjustable kettlebell is a solid choice for home strength training, offering durability, a good weight range, and ergonomic design, though it may not be the best fit if you want quick weight changes or have specific handle size preferences.

The BowFlex SelectTech 840 Kettlebell stands out as a versatile option for home fitness enthusiasts, offering an adjustable weight range from 8 to 40 pounds. This wide range caters to various fitness levels and allows for a variety of exercises such as swings, rows, and squats. The adjustment mechanism is particularly user-friendly, allowing you to change weights with just a turn of a dial, making it easy to switch between exercises quickly.

One of the major benefits is its space-efficient design, which replaces up to six traditional kettlebells, making it a great choice for those with limited workout space. Its compact size (8.8”L x 7”W x 12.5”H) makes it easy to store when not in use. The handle design is comfortable, which can enhance the workout experience.

The inclusion of a 2-month free trial for the JRNY mobile membership is a nice incentive, especially for those looking for guided workouts, but it does require a subscription afterward, which might not appeal to everyone.

The Fitvids Multi-Functional Adjustable Kettlebell Set offers a versatile workout option by combining dumbbells, barbells, and kettlebells in one set. You can adjust the weights between 4 and 30 pounds per single handle, or up to 60 pounds if using both sides together, which gives a good range for beginners to intermediate users. The adjustment system is straightforward: you add or remove weight plates and lock them with collar locks, making it quick and easy to switch between exercises. The set includes multiple plates (4, 5, and 6 pounds) that let you customize the weight precisely. The materials used here are a mix of polyethylene on the outside, which protects floors and resists rust, and a heavy inner mix of iron, cement, and sand, which ensures durability and solid weight. The handles are also coated with polyethylene, which can provide a comfortable grip, though they might feel a bit bulkier compared to metal handles with knurling.

The shape and size are well thought out for multi-function use, but because this set is designed to convert into different equipment, it may be larger and heavier to store than single-purpose kettlebells. This product fits well for users wanting flexibility in their workouts and who have space for a slightly bulkier setup. However, those preferring a simpler, dedicated kettlebell or needing a very compact option might find this set somewhat cumbersome. Positive customer reviews highlight its quality and convenience, making it a solid choice for home fitness enthusiasts seeking variety without buying multiple pieces of equipment.
