Best ValueRank #6 in Kettlebells
Yes4All Adjustable Kettlebell (7.8–40 lb)
by Yes4All
Score
A cast-iron kettlebell that adjusts with plates rather than a dial. Yes4All lists seven settings — 7.8, 12.4, 17.9, 23.9, 29.9, 35.4 and 40 lb — with marked plates and a lock that holds them on the handle, and a wide handle for two-hand swings. It is the cheaper adjustable route next to the BowFlex 840 dial bell: changing weight is a by-hand job rather than a turn of a dial, and like every adjustable bell the body is bigger than a solid bell of the same weight. Sold by Amazon.
- Small rooms where one bell has to cover the weights from light presses to moderate swings
- Beginners who expect to move up in weight over the first year
- You swing more than 40 lb already
- You want to change weight mid-circuit in seconds — a dial bell is faster
- You do high-rep snatches and want a compact competition-shaped bell
Strengths
- ↑Seven settings from 7.8 to 40 lb in one bell, per Yes4All
- ↑Cast-iron handle and plates, not a plastic shell
- ↑Plates are marked, so the current weight is easy to read
- ↑Wide handle takes two hands for swings
Weaknesses
- ↓Changing weight means adding or removing plates by hand — slower than a dial
- ↓Tops out at 40 lb, so strong lifters will outgrow it for swings
- ↓Bulkier than a solid bell at the same weight, so the rack position sits differently

Best Kettlebell for Home Gyms and Beginners (2026): Which to Buy

Ranked alternatives from the same category, with our score and the current price.
The Yes4All powder-coated kettlebell is the default Amazon answer to 'I want one good kettlebell'. Single-piece cast iron, no welds or seams, and Yes4All lists each bell's actual weight within about 3% of the label. The powder coat has a slight texture that Yes4All says grips without chalk, and each weight is colour-coded. The flat bottom matters more than people expect: it lets you do renegade rows or push-ups on the bell without it rocking. Yes4All sells it from 9 to 88 lb. The link opens on the 26 lb bell (Yes4All's listing bullet: "26 Lbs"), single, blue; other weights are on the same listing. Sold by a third-party seller at or under the maker's price, shipped by Amazon (checked 2026-10-21).
The default beginner buy: a solid one-piece cast-iron bell with a vinyl coat that protects your floors and quiets the clank. Sold in single weights from 10 to 50 lb, so you can build a rack a plate at a time without committing to a full set. Delivery note: the 50 lb option we link is sold by Amazon itself, but its listing showed "Usually ships within 1 to 2 months" on 2026-10-17; check the delivery date before you order. Re-checked next pass.
The Amazon Basics enamel kettlebell is an inexpensive 'don't get scammed' kettlebell on Amazon. Solid cast iron core, glossy enamel finish, accurate labeled weight. The catch is that enamel: it's harder than powder coat, which means it doesn't grip chalk as well and feels slicker in sweaty hands. For unweighted-grip work (swings, goblet squats) it's a non-issue. For high-rep snatches or get-ups, you'll want a powder-coated bell. Good emergency-replacement option, or a fine first kettlebell to learn whether you actually like training with bells.
CAP's competition-style bell is the alternative if Yes4All's competition line is out of stock or you want a slightly larger handle. 35mm handle (vs. Yes4All's 33mm) is more forgiving for larger hands but slightly less optimal for very high-rep snatches. The powder coat is thicker than Yes4All's, which means fewer chips but also a slightly slicker feel until it wears in. Same uniform body sizing as any competition bell. Good middle-ground option.
The adjustable option this category was missing — every other pick is a single fixed weight. BowFlex state a dial that swaps between 8, 12, 20, 25, 35 and 40 lb, which replaces six kettlebells in the footprint of one.
