Key Features & Specs
- Weight range: 8 to 40 pounds adjustable in 2-pound increments
- Innovative dial system for quick and easy weight changes
- Sturdy construction with a solid steel core
- Ergonomic handle designed for comfortable grip and multiple kettlebell exercises
- Compact design to save space compared to traditional kettlebell sets

Design & Build
The Bowflex SelectTech 840 Adjustable Kettlebell stands out with its sleek, modern design that blends functionality and durability. Unlike traditional kettlebells, it uses a dial mechanism at the base that lets you select your desired weight quickly and securely. The build quality feels solid, thanks to a steel core surrounded by a protective outer shell that can withstand regular use without chipping or cracking.
The handle is well thought out — wide enough for two-handed use and textured just right to prevent slippage during intense sessions. Plus, the compact footprint means it won’t take up much room, making it ideal for home gyms or apartments. While it’s slightly bulkier than fixed-weight kettlebells, the trade-off for versatility is worth it.

Performance & Real-World Use
In everyday workouts, the Bowflex SelectTech 840 Adjustable Kettlebell performs admirably. Switching weights is fast and hassle-free, allowing you to move seamlessly between exercises and varying resistance levels. The weight increments of 2 pounds provide enough granularity for gradual strength progression or circuit training.
The balance feels a bit different from traditional kettlebells due to the adjustable plates, but after a few sessions, it becomes easy to adapt. It excels in a variety of exercises, from kettlebell swings and goblet squats to presses and rows. However, for advanced kettlebell athletes who rely on ultra-precise weight distribution or heavier weights, this model may have some limitations.
Noise during weight changes is minimal, and the locking mechanism feels secure, so there’s no worry about weights shifting mid-exercise. Cleaning and maintenance are straightforward, thanks to the smooth exterior surfaces.

Pricing & Value
When it comes to pricing, the Bowflex SelectTech 840 Adjustable Kettlebell is positioned in the mid-to-high range compared to single fixed-weight kettlebells, but its adjustability means you’re essentially getting multiple kettlebells in one.
This makes it an excellent value for home fitness enthusiasts who want versatility without investing in a full set of kettlebells. It’s especially suited for beginners to intermediate users who appreciate the convenience of quick weight adjustments and space-saving design. However, budget-conscious buyers or those who prefer ultra-heavy kettlebells might want to consider alternatives.

- Adjustable weight from 8 to 40 pounds in 2-pound increments
- Space-saving design replaces multiple kettlebells
- Quick and easy weight changes with the dial system
- Solid build quality with durable steel core
- Comfortable, ergonomic handle suitable for various exercises
- Quiet and secure locking mechanism
Cons

Final Verdict
Overall, the Bowflex SelectTech 840 Adjustable Kettlebell is a smart investment for those who want a versatile, space-efficient solution for strength training at home. Its easy-to-use dial system and adjustable weight range make it perfect for beginners and intermediate exercisers looking to progress without cluttering their workout space.

If you’re an advanced kettlebell user needing heavier weights or precise traditional balance, you might want to explore other options. But for most home fitness enthusiasts, this product offers an excellent blend of convenience, quality, and performance that justifies the price.
In summary, buy this if you want a compact, adjustable kettlebell that adapts to your evolving fitness needs. Skip it if you require heavy-duty kettlebells for specialized training or are on a tight budget.
