PowerBlock Kettlebell 18-35 lb Review 2026

The PowerBlock kettlebell is designed for home-gym users who want several useful training weights in one compact piece of equipment. The Pro Adjustable Kettlebell 18–35 lb replaces four fixed kettlebells and uses PowerBlock’s magnetic selector pin to switch between 18, 22, 26, and 35 lb.

Quick Verdict

Best for: beginners and intermediate home-gym users who value fast adjustments, compact storage, and durable steel construction.

Skip it if: you need weights above 35 lb, want small and evenly spaced weight jumps, or strongly prefer the round body and rack-position feel of a traditional competition kettlebell.

What Makes the PowerBlock Kettlebell Different?

The biggest difference is the combination of a compact steel body and a selector-pin system. Instead of opening the bell or turning a dial, you set the kettlebell down, move the magnetic pin to the desired position, and lift. Plates not selected remain behind. That makes weight changes substantially faster than plate-loaded adjustable kettlebells.

PowerBlock also keeps the overall footprint small. The unconventional body does not imitate a classic round kettlebell, but the design is intended to remain compact while housing the adjustable plates internally.

Build Quality and Handle

PowerBlock specifies solid-steel construction and a roughly 32 mm competition-style steel handle. The fixed handle size means the grip does not become thicker as weight is added. Smooth body angles are intended to improve control and reduce interference during common kettlebell movements.

The steel construction is a major advantage for a frequently used home-gym tool, but the unusual body shape will feel different from a traditional cast-iron or competition bell, particularly for users who already have strong preferences about cleans and the rack position.

How the Magnetic Selector Pin Works

The selector pin is the strongest usability feature. Insert it at the desired weight setting and lift the bell. The selected plates travel with the handle while the unused plates remain below. The four available loads are 18, 22, 26, and 35 lb.

This is fast enough for workouts where you move from a heavier squat or swing to a lighter press. The main compromise is progression: the jump from 26 to 35 lb is nine pounds, much larger than the earlier four-pound jumps.

Exercises You Can Do

• Kettlebell swings
• Goblet squats
• Deadlifts
• Lunges
• Rows
• Overhead presses
• Farmer and suitcase carries
• Russian twists
• Clean and press, depending on comfort with the body shape

Pros and Cons

Who Is the PowerBlock Kettlebell Best For?

This model is particularly suitable for people building a compact home gym, beginners progressing through basic kettlebell movements, and intermediate users who need a light-to-moderate bell for swings, squats, presses, carries, and accessory work. It also makes sense when quick load changes matter more than having very fine weight increments.

Who Should Avoid It?

Stronger kettlebell users may outgrow the 35 lb ceiling quickly, especially for swings, squats, deadlifts, and carries. PowerBlock offers a heavier 35–62 lb model for that use case. Lifters who prioritize traditional competition-kettlebell geometry may also prefer a round adjustable design such as Bells of Steel.

PowerBlock Kettlebell vs. BowFlex SelectTech 840

Both products emphasize quick adjustment and compact storage. The BowFlex SelectTech 840 offers more weight settings and uses a dial-based system, while the PowerBlock uses four settings selected by a magnetic pin. PowerBlock’s all-steel approach and compact footprint will appeal to users who prioritize straightforward construction; BowFlex may suit users who want more load choices within a similar general range.

PowerBlock Kettlebell vs. Bells of Steel

The Bells of Steel adjustable kettlebell is closer to traditional competition-kettlebell geometry and provides finer internal loading options, but changing its internal plates takes longer. PowerBlock is the more convenient choice when fast changes matter. Bells of Steel is the stronger choice when traditional feel and more granular loading are the priorities.

Limitations to Know Before Buying

• The maximum load is only 35 lb.
• The 26-to-35-lb jump is relatively large.
• The body shape is less traditional than a competition kettlebell.
• There are only four selectable loads.
• The starting 18 lb load may be challenging for some first-time users on presses or technical movements.

Final Verdict

The PowerBlock kettlebell is a practical adjustable option for a small home gym. Its biggest strengths are fast magnetic-pin adjustments, durable steel construction, and the ability to replace four separate kettlebells without taking up a rack of floor space.

The trade-offs are equally clear: the 35 lb ceiling limits long-term progression for stronger users, and the jump from 26 to 35 lb is larger than ideal. For beginners and intermediate trainees who want a compact light-to-moderate adjustable kettlebell, however, the Pro 18–35 lb model offers a strong balance of convenience and durability.

Frequently Asked Questions

What weights does the PowerBlock kettlebell have?

The Pro 18–35 lb model provides four settings: 18, 22, 26, and 35 lb, equivalent to approximately 8, 10, 12, and 16 kg.

How do you adjust a PowerBlock kettlebell?

Set the kettlebell down and move the magnetic selector pin to the desired weight position. When you lift the bell, only the selected plates come with it.

Is the PowerBlock kettlebell good for beginners?

It can be a good choice for beginners who are comfortable starting at 18 lb. The four settings allow progression without buying four individual kettlebells, although 18 lb may be too heavy for some beginners on overhead exercises.

Can you do kettlebell swings with it?

Yes. PowerBlock specifically lists swings among the exercises supported by its adjustable kettlebell, along with presses and squats.

Is 35 lb enough for kettlebell training?

It can cover many beginner and intermediate exercises, but stronger users may eventually need more resistance for swings, squats, deadlifts, and carries. PowerBlock also makes a heavier 35–62 lb adjustable model.
