PowerBlock 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

PowerBlock Adjustable Kettlebell comes out ahead by a narrow margin (4.3 vs 4.2). The gap is mostly about lifters who do more pressing and cleaning than swinging, and prefer the flatter cowbell shape against the wrist — read the strengths below before deciding.

Higher ratedRanked #4 in Best Adjustable Kettlebells

PowerBlock Adjustable Kettlebell

4.3

$72as of May 19

The PowerBlock Adjustable Kettlebell is the alternative shape pick. The cowbell-style flat-angle body genuinely makes overhead presses and rack work more comfortable than the round Bowflex SelectTech 840, but it changes how swings feel — purists prefer the round REP Fitness shape. Four weight settings is the smallest count in this round-up; the magnetic pin adjustment is novel and fast once you learn it. Best for users who care more about press/clean comfort than swing dynamics.

Strengths

— Magnetic pin system for fast adjustment — no dial or twist required
— Flat-angle shape rests more comfortably during cleans and overhead presses
— Rugged steel shell — feels durable in hand

Watch-outs

— Four weight settings only — fewer increments than competitors here
— Cowbell shape (not true kettlebell) changes feel for swings — less natural
— Smaller weight range than the REP Fitness or Bells of Steel

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

PowerBlock Adjustable Kettlebell

Unique cowbell shape in this lineup — REP Fitness, Bowflex SelectTech 840, Bells of Steel, and Yes4All are all traditional round shapes. Magnetic pin adjustment is faster than the REP Fitness twist and the Yes4All disc system, slower than the Bowflex SelectTech 840 dial. Smaller weight range than the REP Fitness or Bells of Steel.

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.
