I Had A $1,140 Kettlebell Set In My Shopping Cart. The One I Bought Instead Loads To 200 Pounds For $129.

Ten cast-iron bells, 555 pounds of iron, $1,139.90 before shipping. I closed the tab with the cursor sitting on the checkout button. The bell I ended up with clamps the Olympic plates I already own, and it cost less than the 40 kg alone.

How One Kettlebell Turns Into A $1,140 Cart

For two years my kettlebell training lived at a commercial gym with a two-tier rack, and I used most of it. Then I built a garage gym. The only kettlebell in it was a 16 kg I had bought years earlier, and the first week at home told me what one bell is worth.

A kettlebell is one weight, forever. That is the whole point of it, and it is also the problem. My press bell was 20 kg. My swing bell was 32. Get-ups sat at 24, and goblet squats wanted something heavier than the press bell and lighter than the swing bell. One 16 kg covers none of that, and every jump is a new purchase.

The jumps are not small, either. Pavel Tsatsouline's Simple and Sinister, the program half the kettlebell world runs, sets its Simple standard for men at 32 kg for both the swing and the get-up, and Sinister at 48 kg. Nobody gets from a 16 kg to a 32 kg swing without the bells in between.

So I did what everyone does and built the set. Presses progress in 2 kg steps, so 12, 14, 16, 18 and 20. Swings and cleans move in 4 kg steps, so 24, 28 and 32. Then a 40 and a 48 for two-hand swings and deadlifts, because the swing keeps growing long after the press stalls. Ten bells. A fixed cast bell is still the best-feeling kettlebell there is, which is why the set was the first thing I priced. Here is the cart, at REP Fitness on September 15, 2026:

I stared at that number for a while. Then I turned around and looked at the plate tree behind me. A pair of 45s, a pair of 35s, four 25s, four 10s and a handful of change plates. Just over 300 pounds of Olympic iron I had already paid for, six feet from a cart asking me to buy 555 pounds more.

The Adjustable Kettlebells Everyone Recommends, And Where Each One Stops

Before I bought anything I went through the adjustable bells, because on paper an adjustable bell is the obvious answer to a $1,140 cart. Each of these is a real product I would still recommend to somebody. None was the answer for me, and the reason is the same each time.

Adjustable #1

Bowflex SelectTech 840

$149
Weight dial8 to 40 lb6 settings

This is the bell every "best adjustable kettlebell" list opens with, and for good reason. Turn the dial to 8, 12, 20, 25, 35 or 40 pounds and lift. Nothing else on this page changes weight faster, and for $149 it is a complete bell with nothing else to buy. If you own no plates and will never swing more than 40 pounds, buy this one and stop reading.

The trouble is that 40 pounds is 18 kg. My swing bell was 32 kg and my get-up bell was 24, and the 840 stops below both. It also carries its weight inside a molded housing with a dial mechanism in the load path, which is a different animal from a lump of cast iron the day it meets a concrete floor. Bowflex covers the parts for two years.

Wins
The fastest weight change here, and the cheapest complete bell.
Stops at
40 pounds, with plastic holding the load.

Adjustable #2

REP Fitness Adjustable Kettlebell

$149.99 to $219.99
3 models8 to 24 kgAbout 8 kg of range each

REP's answer looks more like a real kettlebell and comes in three models: 8 to 16 kg for $149.99, 16 to 24 kg for $219.99, and a 20 to 40 lb version for $159.99. Pick the range you live in and it is a fine bell.

The catch is the word range. Each one spans about 8 kg. Covering 8 to 24 kg means buying two of them for $369.98, and the heaviest model still stops at 24 kg, which is 53 pounds. That is a get-up bell, not a swing bell.

Wins
The truest kettlebell shape of the adjustables under $250.
Stops at
24 kg, and two bells to cover the light end.

Adjustable #3

Bells of Steel Adjustable Competition Kettlebell

$332.99
Steel shell12 to 32 kg0.5 kg steps

If money were no object, this is the adjustable most serious kettlebell people would point you at. Steel shell, iron plates inside, competition size and a 35 mm competition handle, 41 settings from 12 to 32 kg in half-kilo steps. Bells of Steel is honest enough to print on its own page that changing the weight takes one to two minutes, and to suggest buying two if you want a swing weight and a press weight in the same session.

Two of them is $598.99. Even then the ceiling is 32 kg, which is exactly the Simple standard and nothing past it. For $333 I wanted a bell I could not outgrow.

Wins
The closest thing to a fixed competition bell, with the finest increments on the market.
Stops at
32 kg, one to two minutes per change.

I even looked at the cheap fix, the $34.95 Kettle Gryp, a plastic clamshell that gives you a kettlebell grip on top of a dumbbell you already own. It wins on price and portability and nothing else comes close on either. Its maker recommends dumbbells up to 55 pounds, so it stops at 25 kg, and you still have to buy the dumbbells.

The Four Things An Adjustable Kettlebell Has To Get Right

Four bells and one $1,140 cart later, the rubric wrote itself. The same four tests every time, and until a bell passes all four I am buying weight I will have to buy again.

  1. A ceiling above 32 kg.That is where the Simple standard sits, and swings keep growing past it. Every adjustable above stops at or below it.
  2. Steel in the load path.The part that holds the weight while it swings between your knees should not be a plastic housing or a dial mechanism. Iron and steel do not care about the floor.
  3. The plates I already own.Olympic plates are the cheapest iron there is, and most home gyms already have a tree of them. A bell that clamps them costs a handle, not a rack.
  4. A forearm it can live on.Cleans, snatches and presses park the bell on the back of your wrist a hundred times a session. Whatever holds the plates has to be smooth, balanced and quiet.

There is a fifth test I care about less than I expected: changing the weight in under a minute without a tool. A dial is nice. Thirty seconds is fine.

The $129 fix

The One I Bought Instead

The Kensui EZ-BELL is a kettlebell with no weight in it. It is a handle with a 2-inch sleeve sticking out sideways on each side, and you load it the way you load a barbell: slide on the Olympic plates you own, one side then the other, and two spring coils clamp them in place. Two smooth protector shells sit outside the plates, so the thing that lands on your forearm during a clean is a rounded shell and not a plate edge. Empty, it weighs 2.3 pounds.

The MAX is the steel version, and it is rated to 200 pounds. It costs $129 for a single bell. The nylon PRO is the same design rated to 100 pounds for $49, and a pair of either is $95 or $249. I bought one MAX, because I wanted the bell that would still be the bell when my swing passes 40 kg.

Here is the part nobody puts in a headline. What you actually load depends on your plates. The sleeves are 8 cm a side and take any plate with a 2-inch hole and a diameter of 320 mm or less. That means cast-iron 25s fit and 45s do not. Four 25s from my tree make a bell of just over 100 pounds, which covers my swing bell, my get-up bell and my press bell on the same handle. Getting toward the 200-pound rating takes denser, thinner plates than cast iron. I have not needed to yet, and the reviews are candid about the same thing.

Six weeks in, here is how it did on the four tests.

  • Ceiling. Rated to 200 pounds on the MAX, and the only limit I have found is the thickness of my own plates.
  • Steel. The MAX handle and sleeves are steel, the plates are iron, and the spring coils are the only moving part.
  • My plates. It took 25s, 10s, 5s and change plates straight off the tree. I have bought no iron since.
  • Forearm. The shells work. I cleaned it fifty times the first night and had no bruise the next morning.

What It Is Like To Live With

Changing weight is not a dial. Pop the shell, unload, reload, clip. It takes me 30 to 40 seconds a side now that I have stopped fumbling the coil, and one reviewer's line stuck with me because it is true:

"Loading and unloading them can be cumbersome but I knew that going in. I really enjoy using them for EMOM workouts where I don't have to change the weight at all during the entire workout."Braedon S., verified buyer

That is how I use it too. Swings and cleans on one load, then a reload for presses and get-ups. Two reloads a session. If your training is ladders that change weight every set, the Bowflex dial will make you happier, and I mean that.

The feel is the part that surprised me. The plates load horizontally through the middle of the bell instead of stacking up from the bottom, so the weight sits where a cast bell's weight sits, and the shells keep the plate edges off your wrist. Two spring coils and two shells are the whole mechanism.

Two more owners, and the second one is the honest ceiling in practice:

"The horizontal loading design gives it a much more balanced feel compared to other adjustable kettlebells I've tried, and the protective shell system makes training significantly more comfortable on the forearms."Kevin C., verified buyer
"Glad I don't have to buy 20kg+ bells. It'd be tough to get 40kg+ on with the weight sleeve lengths using 230mm plates. 30kg is good without feeling like you're stretching them."Andrew S., verified buyer

Three honest limits. It takes 2-inch Olympic plates only, so standard 1-inch plates will not fit, and the plates are not included at any price. It is not a competition bell: the shells sit wider than a competition handle wants, so if you compete in kettlebell sport you already own the bells you need. And if you own no plates at all, do the sum properly. A MAX plus a plate order is not $129, and the Bowflex is the fair comparison.

Questions I Had Before Ordering

Will it take my plates?
Any plate with a 2-inch (50 mm) hole and a diameter of 320 mm or less. Cast-iron 25s and everything smaller fit. Standard 1-inch plates do not, and full-size bumpers do not either.
How heavy can I really make it?
It depends on how thick your plates are. With 8 cm of sleeve a side, four cast-iron 25s land just over 100 pounds. Reaching the 200-pound rating on the MAX takes thinner, denser plates than cast iron.
What if I do not like it?
Kensui gives you 100 days to send it back for a full refund, no questions asked. It is in stock and ships within 24 hours.

The cart is still sitting on the REP site if I ever want it. What sits on my rack instead cost $129, runs on iron I had already paid for, and is rated higher than the biggest bell in that cart.
