In this review, I’ll walk you through everything you need to know about this product, from its key features to how it holds up in real-world use.

Design & Build
The Bowflex SelectTech 840 Adjustable Kettlebell sports a sleek, modern design that looks right at home in any workout space. Its compact footprint is a major plus, especially for those with limited room. The dial mechanism is intuitive and feels sturdy, giving confidence that the selected weight will stay securely locked in place during your workout.
The handle is coated with a comfortable, non-slip grip that feels great during use and minimizes hand fatigue. Unlike traditional kettlebells, this model has a flat base which adds stability when you set it down, making it safer and more convenient.

Performance & Real-World Use
In practice, the Bowflex SelectTech 840 Adjustable Kettlebell performs impressively. The weight adjustment is smooth and quick, enabling seamless transitions between exercises. Whether you’re doing swings, goblet squats, or presses, the weight distribution feels balanced and natural.
Because it replaces multiple kettlebells, it’s perfect for circuit training or for households with multiple users who have different strength levels. The ability to increase weight in small increments helps with gradual progression and reduces the need to buy several separate kettlebells.
One thing to note is that the overall shape is bulkier than a traditional kettlebell, so certain moves like snatches or cleans might require some adjustment in technique. However, for most common kettlebell exercises, it delivers solid performance.

Pricing & Value
The Bowflex SelectTech 840 Adjustable Kettlebell is priced in the mid-to-high range for home fitness equipment but offers good value considering it replaces up to five traditional kettlebells. For those who want to save space and avoid purchasing multiple kettlebells individually, this product is an efficient investment.
This kettlebell is best suited for fitness enthusiasts who value convenience and versatility, from beginners who want to progress steadily to intermediate users looking for a compact solution. If you’re a serious kettlebell competitor or need very high weights, this might not be the ideal choice.
