REP Fitness Adjustable Kettlebell vs Yes4All Adjustable Kettlebell

Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

The short answer

REP Fitness Adjustable Kettlebell comes out ahead by a clear margin (4.6 vs 4.2). The gap is mostly about intermediate-to-advanced kettlebell users who want competition-shaped swings and cleans without sacrificing space for a full set — read the strengths below before deciding.

Higher ratedRanked #1 in Best Adjustable Kettlebells

REP Fitness Adjustable Kettlebell

4.6

$220as of May 19

The REP Fitness Adjustable is the most refined adjustable kettlebell in this round-up — cast-iron internal plates with proper thermoplastic locking means it feels like a real kettlebell, not a plastic shell with weights inside. Garage Gym Lab and BarBend both rank it the best overall adjustable for 2026. The catch is you commit to one weight range (most users pick the 16 kg bell which adjusts 8-16 kg). For users who want adjustable-kettlebell convenience without sacrificing the swing/clean/snatch feel, this is the pick.

Strengths

— Cast-iron internal plates with nylon thermoplastic fasteners — no plastic shell rattle
— Push-and-twist adjustment is faster than dial-based competitors
— Competition-style shape keeps swing/clean/snatch feel consistent across weights

Watch-outs

— Single size range — pick 8-16 kg, 16-24 kg, or 20-40 lb; no all-in-one bell
— 5 increments per range is fewer than the Bowflex SelectTech 840's 6
— Pricier than the Yes4All or Bowflex SelectTech at MSRP

Ranked #5 in Best Adjustable Kettlebells

Yes4All Adjustable Kettlebell

4.2

$60as of May 19

The Yes4All Adjustable is the value pick — about a third the price of the REP Fitness and nearly half the Bowflex SelectTech 840. Cast iron handle plus disc-and-spacer construction means it feels more authentic than plastic-shell alternatives in this price tier, and the 20-40 lb range covers most beginner programming. The trade-offs are adjustment speed and brand support, but for a sub-$60 entry-level option that lets you try kettlebell training without committing $200, it's hard to beat.

Strengths

— Cheapest adjustable kettlebell in this round-up by a wide margin
— Cast iron handle with steel components — better than plastic-shell budget alternatives
— 20-40 lb weight range covers most beginner programming

Watch-outs

— Slower adjustment than the Bowflex SelectTech 840 dial or PowerBlock pin
— Cast iron is less durable on drops than the Bells of Steel steel shell
— Heavier increments (4.6-6 lb per disc) vs Bells of Steel's 0.5 kg micro-loading

How they stack up

REP Fitness Adjustable Kettlebell

Most refined feel of the picks here — beats the Bowflex SelectTech 840 and PowerBlock on swing dynamics due to the competition-style shape. Loses to the Bowflex SelectTech 840 on quick-change convenience and to the Yes4All on price. Single-range design means you may eventually want a second bell for a different weight bracket.

Yes4All Adjustable Kettlebell

Cheapest pick by far — significantly under the Bowflex SelectTech 840, PowerBlock, REP Fitness, and Bells of Steel. Cast iron build is a real advantage over the Bowflex SelectTech 840's plastic shell at this price. Loses to every other pick on adjustment speed and weight ceiling.
