A full kettlebell rack means a row of cast-iron bells eating floor space, most of them sitting idle while you use one. A good adjustable bell collapses that whole row into a single handle: turn a dial, slide a pin, or swap a plate, and the weight you need is in your hand in seconds.
The bell worth buying earns it three ways: a weight range wide enough to grow into, an adjustment you will actually use mid-workout, and a handle and base that feel right for swings, cleans, and presses. That suits a beginner laddering up by a few pounds at a time, a strength trainer cycling heavy sets, and anyone living somewhere a wall of separate bells simply will not fit. The picks below lead with the best sellers, so the most-bought models come first.

How to choose an adjustable kettlebell
The headline number on an adjustable bell is its weight range, but the bell that actually stays in your routine balances several things the spec sheet underplays. A wide range is wasted if changing weight is fiddly enough that you skip it; a quick dial is wasted if the bell feels nothing like the swings you want to do. Here is what separates a bell you reach for daily from one that gathers dust.
Adjustment mechanism
This is the feature you will touch most. Three approaches show up here. A dial system, like the BowFlex SelectTech, sets the weight by turning a selector before you lift the handle out of its base, the fastest mid-workout change in this group. A push-and-twist or quick-change lock, used by Rep Fitness and ByZoom, swaps settings in seconds without tools. Plate-loaded designs, the Apex handle and the bolt-secured Bells of Steel, take longer to change but tend to cost less and feel rock solid once locked. Match the mechanism to how often you change weight inside a single session.
Weight range and increments
Pick a range you can grow into, not just one you can lift today. The light bells here start around 3.5 to 8 lb, friendly for pressing, get-ups, and learning form; the heavier ones reach 40 lb and beyond for swings and loaded squats. Increment size matters too: small steps, like the 0.5 kg jumps on the Bells of Steel, let you progress gradually, while bigger gaps between settings can feel like a leap. If more than one person will share the bell, a wider range covers everyone.
Handle and shape
The handle decides how the bell feels in your hand and against your forearm. A thicker handle taxes grip more; a competition-style 35 mm handle, as on the Bells of Steel, matches the diameter serious lifters train on. The shape of the bell body matters during cleans and racked holds, where the weight rests on your forearm, so a curved or competition-shaped shell is gentler there than a boxy one. If swings and cleans are central to your training, prioritize handle feel over raw features.
Build and base
Cast iron and steel bells feel dense and stable; aluminum-and-ABS designs are lighter to ship and easier on floors but carry less heft per size. A flat, stable base lets the bell sit upright for renegade rows, push-ups, and tidy storage, and a rattle-free internal lock keeps plates from clacking during explosive reps. Check the base before buying if you plan to use the bell as a floor anchor.
Space, portability, and budget
The whole point of an adjustable bell is replacing a shelf of fixed ones, so footprint is the payoff. The most compact option is no bell at all: a converter like the Kettle Gryp turns dumbbells you already own into a kettlebell and packs into a gym bag. Plate-loaded handles lean on plates you may already have, keeping cost down. Dial and quick-change bells cost more up front but bundle the whole range into one purchase.
BowFlex SelectTech 840 (Dial Adjust, 8-40 lb, 6 Settings)
The best seller in this group is also the easiest to live with. A single dial sets the weight from 8 to 40 lb across six settings, 8, 12, 20, 25, 35, and 40 lb, so one bell replaces up to six and you can jump from a light pressing weight to a heavy swing without leaving the spot you are standing in. That fast change is what makes circuits and full-body flows, swings, rows, squats, and twists, practical at home, and it ships with a two-month trial of the JRNY membership for guided phone or tablet workouts if you want structure.
Pros
- Dial change is the fastest mid-workout swap here
- Replaces six kettlebells in one footprint
- Sensible 8-40 lb spread for swings to presses
- Space-saving design works in almost any room
- Includes a two-month guided workout trial
Cons
- Tops out at 40 lb, light for advanced swings
- Larger body than a fixed bell of the same weight
- Dial mechanism is more complex than a plate lock
Best for: circuits and flows where you change weight constantly and want it instant.

Kettle Gryp (Converts Dumbbells, Under 1 lb, Portable)
The cleverest pick here is barely a kettlebell at all. The Kettle Gryp is a hinged ABS handle that clamps around a dumbbell you already own, open it, drop the dumbbell in, close it, and snap the patented latch, turning any compatible dumbbell into a kettlebell in seconds. Because it borrows your existing weights, its range is whatever your dumbbells cover, up to a 55 lb maximum, and at under a pound it slips into a gym bag or carry-on for hotel and travel workouts. It fits most adjustable dumbbells and bare-metal handles up to 1.5 inches thick, but skips most thick vinyl or neoprene-coated handles.
Pros
- Uses dumbbells you already own, no new weights
- Under a pound and packs anywhere
- Patented secure latching closure
- Impact-resistant ABS, foam, and stainless build
- Budget price and zero added storage footprint
Cons
- Requires dumbbells; not a standalone weight
- Will not fit most coated or very short handles
- 55 lb dumbbell ceiling caps the load
Best for: dumbbell owners and travelers who want kettlebell moves without buying more iron.

Apex 20lb Handle (Cast Iron, Loads 1″ Plates to 50 lb)
The Apex takes the plate-loaded route, and for anyone who already owns weight plates it is the cheapest way into a wide range. The set is a 15 lb weighted handle, four removable spacer disks, a 5 lb bottom plate, and a center pin, which together make a 20 lb bell out of the box and climb to 50 lb using standard 1-inch 2.5, 5, or 10 lb plates. The solid cast-iron, powder-coated build feels stable and the traditional U-shaped handle suits swings, goblet squats, presses, and rows, one or two-handed. Changing weight means loading plates rather than flicking a dial, so it is slower between sets.
Pros
- Cheapest path to 50 lb if you own plates
- Solid cast iron with powder-coated finish
- Comfortable U-bar handle for two-handed work
- Uses common standard 1-inch plates
- Comes with spacers and a bottom plate to start
Cons
- Plate changes are slower than a dial or twist lock
- Needs 1-inch plates you supply for full range
- Loaded shape is less compact than a sealed bell
Best for: home gyms that already have standard plates and want maximum range for the money.

Rep Fitness 40 lb (Push-and-Twist, 5 Settings, Matte Steel)
Rep Fitness builds the quick-change bell for people who care how it feels under load. A simple push-down-and-twist selects among five settings, replacing five separate bells, and Rep states it adjusts faster than any other on the market. The matte powder-coated surface is deliberately grippier than the glossy shells some rivals use, sweaty-hand security that matters during high-rep swings and snatches. Internal nylon thermoplastic retainers and individually fastened plates keep the load tight and quiet, and a rubber bottom protects the floor. The 40 lb version covers swings, deadlifts, squats, get-ups, and presses for most trainers.
Pros
- Tool-free push-and-twist change, very fast
- Grippy matte finish for sweaty hands
- Rugged internal retainers, individually secured plates
- Floor-friendly rubber base
- Backed by a full-service equipment company
Cons
- Premium tier pricing
- Five settings, fewer steps than some rivals
- 40 lb ceiling may limit stronger swing work
Best for: serious home lifters who want fast changes and a grippy, quiet bell under load.

Rep Fitness 24 kg (Push-and-Twist, 5 Settings, Heavier Range)
This is the heavier sibling of the bell above, built for trainers who have outgrown a 40 lb ceiling. It keeps everything that makes the Rep adjustable good, the push-and-twist change, five settings replacing five bells, the non-slip matte finish, rugged internal retainers, and the floor-saving rubber base, but tops out at 24 kg, roughly 53 lb. That extra headroom suits heavy two-handed swings, loaded squats, and progressing the big movements without buying a second, heavier bell. The trade-off is the highest price in this comparison and the same five-step granularity as its lighter twin.
Pros
- Reaches roughly 53 lb for heavier training
- Same fast tool-free push-and-twist change
- Grippy matte finish and quiet, secure plates
- Floor-friendly rubber base
- One bell covers a wide working range
Cons
- Highest price in this group
- Five settings spread across a wider range
- Heavier and bulkier than the lighter version
Best for: stronger lifters who need real heavy-swing headroom from a single adjustable bell.

Yes4All Adjustable (7-in-1 Cast Iron, 6 Settings to 40 lb)
The Yes4All offers cast-iron heft and a wide spread at a middle price. Six durable cast-iron plates give seven configurations in one bell, with six weight settings up to 40 lb, and a lock-and-slide mechanism swaps plates in seconds for smooth transitions between exercises. A textured, non-slip wide handle holds up during sweaty two-handed work, and a flat protective base lets the bell sit upright for renegade rows, handstands, and mounted pistol squats. Rated for home and commercial use, it is the heavy-iron alternative to the lighter aluminum bells, growing with you as your strength builds.
Pros
- Six cast-iron plates, seven-in-one versatility
- Quick lock-and-slide plate changes
- Textured non-slip wide handle
- Flat base for upright storage and floor moves
- Rated for both home and commercial gyms
Cons
- 40 lb ceiling caps heavy swing progression
- Cast iron is heavier to handle than aluminum
- Plate swap is slower than a dial system
Best for: those who want dense cast-iron feel and six steps without paying the premium tier.

VEVOR 7-Level Light (3.5-22.5 lb, Die-Cast Aluminum and ABS)
The lighter VEVOR is the gentlest on-ramp here, with seven precise levels, 3.5, 7, 10, 13, 16, 19.5, and 22.5 lb, ideal for learning form, pressing, get-ups, and a scientifically paced progression where each small step is its own setting. An electroplated aluminum-alloy handle pairs with a shock-absorbing ABS body, and a flat bottom keeps it stable and easy to store. As a 7-in-1, it folds a starter range into one compact, budget-friendly unit. The trade-off is a low 22.5 lb ceiling and lighter materials than cast iron, so dedicated heavy swingers will outgrow it.
Pros
- Seven fine increments from a gentle 3.5 lb
- Great for beginners, presses, and get-ups
- Lightweight aluminum handle with ABS shock body
- Flat stable base for storage and floor work
- Compact 7-in-1 at a budget price
Cons
- Low 22.5 lb ceiling limits heavy swings
- Aluminum and ABS feel lighter than cast iron
- Lesser-known brand than the majors here
Best for: beginners and lighter-load training that rewards small, precise weight steps.
Budget tier. Check price on Amazon
VEVOR 7-Level Heavy (5-44 lb, Die-Cast Aluminum and ABS)
The heavier VEVOR keeps the same seven-level design and materials but shifts the whole range up, 5, 11.5, 18, 24.5, 31, 37.5, and 44 lb, so it spans from a light warm-up to a 44 lb top end suited to swings and loaded squats. The electroplated aluminum-alloy handle and shock-absorbing ABS body carry over, as does the flat, stable base for storage and floor exercises. With wider spacing between steps than its lighter twin, it is the better single-bell choice for someone who wants real progression headroom while keeping the space-saving 7-in-1 format.
Pros
- Wide 5-44 lb range in one bell
- Seven levels cover warm-up to heavy swings
- Lightweight aluminum handle, shock-absorbing ABS
- Flat stable base for storage and floor moves
- Space-saving 7-in-1 at a mid-range price
Cons
- Bigger jumps between settings than the light model
- Aluminum and ABS feel lighter than cast iron
- Lesser-known brand than the majors here
Best for: one-bell home setups wanting a broad range without stepping up to premium iron.

Bells of Steel (18-in-1, Competition Shell, 0.5 kg Steps)
For trainers who treat kettlebell work seriously, the Bells of Steel is the most authentic feel here. It is an 18-in-1 bell with a steel competition-style shell and a 35 mm handle matching the diameter competition lifters train on, and crucially it adjusts in fine 0.5 kg and 1 kg increments from 12 to 20.5 kg, far smaller steps than any other bell in this group. Swapping plates uses the included Allen key and wrench to remove a bottom screw and loosen a nut, slower than a dial but rock solid once set. The ergonomic shape sits cleanly on the forearm for cleans and racked holds.
Pros
- Fine 0.5 kg and 1 kg increments for gradual progress
- Competition 35 mm handle and steel shell
- 18 configurations from one ergonomic bell
- Forearm-friendly competition shape for cleans
- Includes wrench and nut for adjustment
Cons
- Tool-based plate swap is the slowest here
- Premium tier pricing
- 20.5 kg ceiling, no ultra-heavy top end
Best for: dedicated kettlebell training that values competition feel and small, gradual weight steps.

ByZoom Pure Series 40LB (5-in-1 Quick-Change, Curved Handle)
The ByZoom Pure Series chases comfort and looks alongside fast changes. A patented quick-change lock swaps among five settings in seconds, built for HIIT transitions where setup time eats into your heart rate, and the 40 lb model sits in a lineup that also offers 30 and 50 lb maximums. Its signature is an ergonomic curved surface engineered to contour to the forearm, aimed at the bruising heavy cleans and overhead presses can cause against a boxy bell. Precision plates stay rattle-free and silent during explosive reps, a flat stable base anchors renegade rows and push-ups, and it comes in white or black to suit the room.
Pros
- Patented quick-change lock for fast HIIT swaps
- Curved handle surface eases forearm contact
- Rattle-free, silent plates during explosive reps
- Flat stable base for floor work and storage
- White or black finish, plus extended support
Cons
- Premium tier pricing
- Five settings, fewer steps than the finest here
- Lesser-known brand than the majors here
Best for: HIIT and circuit users who want quick swaps and a kinder feel on the forearm.

The verdict
Best overall
The BowFlex SelectTech 840 takes the top spot. It is the best seller here and the most frictionless to use: a single dial moves you from 8 to 40 lb across six settings before you even lift it out of the base, so swings, rows, squats, and twists flow without breaking stride. Replacing six bells in one compact footprint, with a guided-workout trial bundled in, it is the bell most people will actually keep reaching for. Check price on Amazon
Best value
The Kettle Gryp wins on value. At a budget price and under a pound, it converts dumbbells you already own into a kettlebell, so its range costs you nothing extra and it stores in a drawer or travels in a bag. If you own bare-metal or adjustable dumbbells up to its 55 lb limit, it delivers kettlebell swings, cleans, and presses for a fraction of any standalone bell. Check price on Amazon
Best premium
The Bells of Steel is the premium pick. Its steel competition shell, 35 mm handle, and uniquely fine 0.5 kg increments give the most authentic kettlebell feel and the smoothest progression in the group, 18 configurations from one ergonomic bell. If you would rather have fast tool-free changes and a grippy heavy ceiling, the Rep Fitness 24 kg is the standout there. Check price on Amazon
Frequently asked questions
What weight range should a first kettlebell cover?
For learning form and pressing, a range starting light, around 8 lb or even the 3.5 lb on the lighter VEVOR, keeps early sessions controlled. For swings and squats you will quickly want more, so a bell reaching 40 lb or beyond gives room to progress. Picking one wide-range adjustable bell, rather than a single fixed weight, means you rarely outgrow it.
Which adjustment type is fastest between sets?
A dial system like the BowFlex changes weight the instant you turn the selector, the quickest here. Push-and-twist and quick-change locks, as on the Rep Fitness and ByZoom bells, take only a few seconds and need no tools. Plate-loaded designs, the Apex handle and the bolt-secured Bells of Steel, are the slowest because you physically add or remove plates, though they feel very solid once set.
Are adjustable kettlebells as sturdy as fixed ones?
Quality adjustable bells use rugged internal retainers and individually secured plates to stay tight and quiet during explosive reps, and a rattle-free, locked load behaves much like a solid bell. Cast-iron and steel models feel densest; aluminum-and-ABS designs are lighter for the same size. The main practical difference is bulk, since an adjustable body is larger than a fixed bell of the same weight.
Can I really turn my dumbbells into a kettlebell?
Yes, that is exactly what a converter like the Kettle Gryp does: a hinged handle clamps around a dumbbell and latches shut, giving you a kettlebell grip for swings and cleans. It fits most bare-metal and adjustable dumbbell handles up to 1.5 inches thick, with a 55 lb dumbbell ceiling, but skips most thick vinyl or neoprene-coated handles, so check your dumbbells against the compatibility guidance first.
Do I need a flat base on the bell?
A flat, stable base matters if you plan to use the bell as a floor anchor, for renegade rows, push-ups on the handles, or mounted pistol squats, and it also lets the bell stand upright for tidy storage. Most picks here include one. If you only swing and press, base shape matters less than handle feel and weight range.
