The Bowflex SelectTech 840 adjustable kettlebell has become a popular choice for home fitness enthusiasts who want the benefits of kettlebell training without dedicating a whole rack to different weights. Instead of buying eight separate kettlebells, this single unit lets you dial from 8 to 24 pounds in seconds. Our editorial team compared specifications, buyer feedback, and key decision factors to bring you this honest review.

Design and Build Quality

The SelectTech 840 features a steel core encased in a durable plastic housing. The base is rubberized to protect floors and provide stability when you rest it between sets. The handle is contoured and textured, offering a secure grip even during sweaty workouts. The dial mechanism on the side is intuitive: turn it to your desired weight, place the kettlebell on the base, and twist to lock. The whole process takes about five seconds.

One concern is the overall bulk. At 24 pounds, the kettlebell measures about 10 inches in diameter, which is larger than a traditional 24-pound cast-iron kettlebell. This extra size can affect exercises like snatches or high pulls, where the kettlebell needs to pass close to the body. However, for most standard moves, the size is manageable.

Performance and Versatility

The SelectTech 840 shines in versatility. With eight weight options, you can progress gradually from 8 to 24 pounds, which is ideal for beginners and those recovering from injury. The weight adjustment is smooth and secure, and the kettlebell feels solid during swings, squats, and presses. The handle width is comfortable for two-handed swings, though some users with larger hands may find it slightly narrow.

Compared to traditional kettlebells, the SelectTech 840 has a different center of gravity. The weight is distributed more evenly, which can make certain ballistic movements feel less natural. Advanced users may notice a difference in momentum, but most casual exercisers will not mind.

Ease of Use and Comfort

Changing weights is straightforward, and the base makes it easy to store the kettlebell upright. The grip is comfortable, with a rubberized texture that prevents slipping. The wide handle opening allows for both single and double-handed grips. The base is stable, so you can safely rest it on the floor between sets without worrying about it tipping over.

One minor issue is the plastic base can be slippery on hardwood or tile floors, especially when you set it down quickly. A yoga mat or rubber flooring solves this problem.

Cleaning and Maintenance

Cleaning the SelectTech 840 is simple. Wipe the plastic and rubber surfaces with a damp cloth and mild soap. Avoid submerging it in water or using harsh chemicals, as they may damage the plastic. The dial mechanism should be kept free of dust and debris. Periodically check the locking mechanism to ensure it clicks into place securely.

Common Buyer Complaints

While the majority of reviews are positive, some users have noted a few drawbacks. The bulkiness is a common complaint, especially for those who are used to traditional kettlebells. Some users find the maximum weight of 24 pounds too light for advanced training. A few have reported that the dial can be stiff when changing weights, but this tends to loosen with use. The price is higher than a single traditional kettlebell, but when you consider the cost of eight separate kettlebells, it is a reasonable trade-off.

Who Should Buy the Bowflex SelectTech 840?

This adjustable kettlebell is perfect for home gym users who want to save space and money. It is great for beginners who are still figuring out their ideal weight, and for anyone who likes to switch weights between exercises without cluttering their workout area. It is also a good option for travelers or people with limited storage.

If you are an experienced kettlebell enthusiast who values the authentic feel of cast iron, you may prefer a traditional kettlebell. The SelectTech 840 is not a replacement for a competition-style kettlebell, but it is a fantastic all-in-one tool for general fitness.

Final Verdict

The Bowflex SelectTech 840 earns a rating of 4.6 out of 5 stars. It delivers on its promise of convenience and versatility, with a solid build and comfortable grip. The only significant downsides are the bulk and the weight limit, which may not suit advanced athletes. For the majority of home exercisers, this adjustable kettlebell is a smart investment that will serve you well for years.

Questions before you buy

How does the weight adjustment work on the Bowflex SelectTech 840?

The kettlebell has a dial on the side. Turn it to select the desired weight from 8 to 24 lbs, then place the kettlebell back on the base and twist the dial to lock. The internal mechanism adds or removes weight plates automatically.

Is the Bowflex SelectTech 840 suitable for swings?

Yes, but the shape is more compact than a traditional kettlebell, so some users find the swing feels different. The handle is comfortable, but the wider base may require more space. It works well for Russian swings, goblet squats, and presses.

Can I use the Bowflex SelectTech 840 for double kettlebell exercises?

You can, but you would need two units, which is expensive. Each unit is bulky, so double kettlebell work may feel awkward. Most users prefer traditional kettlebells for doubles.

How does the Bowflex SelectTech 840 compare to a traditional kettlebell?

Traditional kettlebells are simpler, more durable, and have a classic feel. The SelectTech 840 offers adjustable weight and a comfortable grip, but it is bulkier and has a plastic base. The trade-off is convenience versus authenticity.

Is the Bowflex SelectTech 840 worth the price?

If you would otherwise buy multiple kettlebells, the price is competitive. It costs more than a single traditional kettlebell, but it replaces 8 weights. For home gyms with limited space, it is a smart investment.
