Bowflex SelectTech 840 Adjustable Kettlebell

4.5

5 sources$149as of Oct 2

The Bowflex SelectTech 840 consolidates six kettlebells into a single compact unit that maintains a consistent footprint regardless of weight selection. Shredded Dad found the dial adjustment system seamless, allowing rapid changes between sets with tactile confirmation for efficient circuit training. However, Men's Fitness noted the handle lacks an ergonomic groove for resting against the forearm during overhead presses or rack positions. The polycarbonate construction carries an explicit 'Do Not Drop' warning because impact can damage the internal locking mechanism, and CNET reported that JRNY app access is limited to tablets and smartphones without TV support.

Strengths

— Replaces six individual kettlebells (8 to 40 lbs) in a single compact unit, saving significant floor space.
— Features an easy-to-use dial adjustment system that allows for rapid weight changes between sets with a tactile click confirmation.
— Maintains a consistent overall shape and footprint regardless of the selected weight setting.

Watch-outs

— Constructed primarily from polycarbonate plastic rather than solid metal, carrying an explicit 'Do Not Drop' warning on the dial.
— The handle is welded to the base and lacks a sculpted ergonomic groove for resting against the forearm during overhead presses or rack positions.
— Weight increments are non-linear (8, 12, 20, 25, 35, 40 lbs), which may not suit users seeking consistent step-ups.

Ranked #2 in Best Adjustable Kettlebells

Titan Adjustable Competition Style Kettlebell

4.3

7 sources1 derived$199.99as of Oct 2

The Titan Adjustable Competition Style Kettlebell features a consistent cast iron shell that maintains identical dimensions from 12 to 32 kilograms, allowing for smooth snatches and cleans without shifting balance. Garage Gym Reviews found this uniform shape prevents the awkward hand feel common in other adjustable models, while the ergonomic handle supports comfortable gripping during high-repetition exercises like Turkish get-ups. However, weight adjustment is time-consuming because it requires tools to unscrew internal bolts and manually add or remove unlabeled plates, a process that can take up to two minutes per change. This product fits athletes who prioritize consistent form for ballistic movements over rapid weight transitions, but those seeking quick adjustments should look elsewhere.

Strengths

— Competition-style shell maintains a consistent footprint across all weight settings, allowing for smooth snatches and cleans.
— Adjustable from 12 kg to 32 kg (approximately 26.5 lbs to 70.4 lbs), effectively replacing up to 19 individual kettlebells.
— Cast iron construction provides a durable build that remains stable and well-balanced when properly tightened.

Watch-outs

— Weight adjustment is time-consuming, requiring tools to unscrew internal bolts and manually add or remove plates.
— Internal weight plates are not factory-labeled, forcing users to identify them by trial or mark them themselves.

How they stack up

Bowflex SelectTech 840 Adjustable Kettlebell

This kettlebell features a rapid push-down and twist dial adjustment system, which is significantly faster than the manual plate loading required by both Bells of Steel and Titan models. However, its polycarbonate construction carries a 'Do Not Drop' warning, contrasting sharply with the durable steel or cast iron builds that reviewers found safe to drop for the other three products.

Titan Adjustable Competition Style Kettlebell

This model shares the consistent competition-style shape and 35mm handle diameter of the Bells of Steel kettlebell, ensuring proper balance for snatches and cleans. However, it requires tools to unscrew internal bolts for adjustment, whereas the Bells of Steel version allows manual plate swapping without extra hardware.
