Yes4All Adjustable Kettlebell Set Review 2026: Worth Buying?

Home gyms get crowded fast. A rack of fixed kettlebells eats floor space and your budget at the same time. The Yes4All Adjustable Kettlebell Set promises a simple fix. One cast iron bell. Seven weight settings. One small footprint in the corner of your room.

But does it actually swing like a real kettlebell? Or does it rattle, slip, and collect dust after two weeks? I spent time with this bell, read through hundreds of owner reports, and compared it against the big names in the adjustable category.

This review covers the unboxing, the lock system, the handle feel, the honest weak spots, and the three alternatives worth checking before you click buy.

In a Nutshell:

• Weight range runs from 7.8 LB to 40 LB across seven settings. You get a 15 LB cast iron handle unit, a 5 LB base plate, and stackable discs. That covers warm up swings, goblet squats, and heavy single arm presses from one bell.
• The cast iron shell is the headline feature. Most budget adjustable bells use plastic housings. This one uses solid cast iron with a powder coated finish, so it feels much closer to a traditional kettlebell than the price suggests.
• Weight changes take roughly 20 to 30 seconds. That is slower than a dial system. It is fine for strength blocks. It is annoying for fast circuit work where you switch loads every minute.
• The 40 LB ceiling is the biggest limit. Strong lifters will outgrow it inside a year. Two handed swings at 40 LB stop feeling heavy quickly for experienced users.
• Value is excellent for beginners and intermediate lifters. It usually sits well under the category average price of around $165, which makes it one of the cheapest ways to own a full light to medium kettlebell range.
• Main complaints involve the locking collar and slight wobble. Some owners report the lock loosening during high rep swings, so a quick check between sets is smart.

What Is the Yes4All Adjustable Kettlebell Set?

Last update on 2026-10-18 / Affiliate links / Images from Amazon Product Advertising API

The Yes4All Adjustable Kettlebell Set is a single kettlebell that changes weight using removable internal plates. The core is a 15 LB cast iron handle unit shaped like a standard bell top. A 5 LB bottom plate closes the base. Between those two pieces you stack cast iron discs to reach your target load.

The full set spans 7.8 LB at its lightest to 40 LB at its heaviest, giving you seven usable weights. Yes4All lists the assembled size at roughly 12 inches long by 7 inches wide by 7 inches high. That is smaller than a shoebox stack and light enough to carry with one hand.

Yes4All has sold cast iron fitness gear on Amazon for over a decade, and this bell follows the same formula: plain, heavy, and cheap in the best sense of the word.

Unboxing Experience: What Arrives at Your Door

The box arrives heavier than expected and the courier will not thank you. Mine showed corner dents, which is normal for 40 pounds of iron in cardboard. Inside, the parts sit in molded foam with a thin plastic wrap over each disc.

You get the handle unit, the base plate, the weight discs, the locking hardware, and a small instruction sheet. There is no storage tray and no exercise guide, so the plates live loose on your floor unless you sort them yourself.

First impression on lifting the handle out: the iron feels dense and the powder coat looks even. First disappointment: a faint machine oil smell and light grease residue on the plate edges. Wipe every piece with a dry cloth before your first session. Assembly takes about three minutes with no tools.

Build Quality and Materials Explained

The shell and plates are cast iron. That single fact separates this bell from most cheap adjustable kettlebells, which hide steel plates inside a plastic housing. Plastic cracks when dropped. Iron chips and keeps working.

The powder coated finish gives a dry, slightly textured surface that holds chalk reasonably well. The welds on the handle unit are tidy. The base plate sits flat, so the bell does not rock during renegade rows or push ups on the handle.

Casting quality is good but not premium. Expect small burrs on plate edges and tiny finish blemishes near the seams. None of these affect function. The real weak link is the plastic locking collar and the thin spacer discs, which feel cheap next to the iron. Treat the lock gently and it holds; crank it hard and the threads will complain.

How the Weight Adjustment System Works

You unscrew the lock at the base, lift the bottom plate away, add or remove discs on the center post, then reseat the plate and tighten. The process takes 20 to 30 seconds once you learn it. The first few attempts take longer because disc order matters.

Each disc carries a stamped weight, so you add numbers yourself. The bell has no external weight window and no dial, which means you cannot glance at it mid workout and know the load. Keep a sticky note on the wall with your settings.

Secured properly, the stack stays quiet. Secured loosely, you get a dull knock on every swing. That knock is your warning sign, not a defect. Stop, retighten, and continue. Compared with dial driven bells, this system trades speed for a lower price and fewer moving parts.

REP Fitness Adjustable Kettlebell

Handle Comfort and Grip Feel

The handle is the part your hands judge in the first ten seconds. Yes4All uses a wide window with a smooth top arc. Two hands fit side by side for swings without knuckle crowding, which is not true of every 40 LB bell.

The powder coat offers moderate grip. It is grippier than a painted competition bell and less aggressive than a raw cast finish. Sweaty palms will slide a little, so chalk helps on high rep sets.

Handle thickness sits in the middle of the range. It feels comfortable for cleans and snatches without shredding your forearms. The corners where the handle meets the body are the sore spot, since the bell can bang the wrist during racked positions until your technique cleans up. Wrist sleeves solve this during the learning phase.

Workout Performance: Swings, Cleans, and Presses

Two handed swings feel the most natural. The flat base and centered load keep the bell tracking straight through the hip hinge. At 30 LB and 40 LB the bell moves like a standard cast iron bell, which is the whole point.

Goblet squats, deadlifts, and single arm rows all work well. The wide handle gives your hands room and the flat bottom lets you set the bell down without it rolling.

Cleans and snatches are where the shape shows its limits. The body is slightly taller and boxier than a round competition bell, so it lands on the forearm with a bit more slap. Turkish get ups feel stable only when the lock is fully tight. Overhead work with any plate loaded bell deserves a safety check first. Treat the lock inspection as part of your warm up.

Space Saving and Storage Benefits

This is the strongest practical reason to buy. One bell replaces roughly five to seven fixed kettlebells. That is a stack of iron shrunk into a footprint about the size of a dinner plate.

Assembled, it slides under a bed, sits in a closet corner, or tucks behind a door. Disassembled, the plates stack flat, which suits apartment owners who hide gear before guests arrive.

There is no storage rack or caddy included, so loose discs will wander across your floor. A small plastic tray or shoe box fixes that for a few dollars. Weight is also manageable for travel between rooms or houses, though 40 pounds of iron in a car trunk is not something you want to do weekly. For small spaces, the space savings are real and immediate.

What the Yes4All Kettlebell Does Not Do Well

Honest reviews list the misses. Here are the clear ones.

The 40 LB ceiling is low. Intermediate lifters hit it within months on swings and deadlifts. There is no expansion kit, so your only route up is buying another bell.

Weight changes are slow. Circuit training with load jumps every set becomes a chore. Dial systems beat this bell by a wide margin on convenience.

The locking collar is the weak component. Owners of similar Yes4All handle style products regularly report collars working loose during swing volume. Retighten often.

Finish quality varies between units. Some arrive with chipped coating or minor casting flaws. Customer service exists but is slow, and replacement parts are not easy to source. Finally, there is no weight display, no coaching material, and no storage solution.

Pros and Cons of the Yes4All Adjustable Kettlebell Set

Pros

• Cast iron construction instead of plastic, which gives a traditional bell feel at a budget price
• Seven weight settings from 7.8 LB to 40 LB replace a small rack of fixed kettlebells
• Wide handle fits two hands comfortably for swings and goblet work
• Flat, stable base allows floor exercises and tidy storage
• Compact footprint suits apartments, bedrooms, and small garages
• Priced well below the category average for adjustable kettlebells

Cons

• Maximum load stops at 40 LB with no expansion option
• Weight changes take 20 to 30 seconds and require handling loose plates
• Plastic locking collar can loosen during high rep swings
• No external weight indicator, so you calculate the load yourself
• No storage tray, carry case, or workout guide included
• Finish and casting quality are inconsistent across units

Yes4All vs BowFlex SelectTech 840: Which One Wins?

These two bells target the same buyer and solve the problem differently. The BowFlex SelectTech 840 adjusts from 8 LB to 40 LB with a dial, and switching weights takes about two seconds. That convenience is genuinely hard to beat for circuit training.

The trade off is material. The 840 uses a plastic outer shell. It looks tidy, but it will not survive drops the way iron does, and the shape feels bulkier against the forearm.

Yes4All wins on price, material honesty, and repairability. BowFlex wins on speed, weight display, and polish. If you train in long strength blocks and want iron under your hand, pick Yes4All. If you change weights every ninety seconds, pay extra for the dial.

Price and Value for Money in 2026

Adjustable kettlebells average around $165 across the market. The Yes4All set typically lands noticeably below that, which makes it one of the cheapest routes into a multi weight kettlebell setup.

Run the math against fixed bells. Buying 10, 15, 20, 25, 30, 35, and 40 LB cast iron kettlebells separately costs several hundred dollars and fills a shelf. This single bell covers that span for a fraction of the cost.

Value is strongest for beginners, returning lifters, and anyone training in a shared living space. Value drops sharply for strong lifters who already swing 24 kg and above, since the ceiling arrives too fast. Think of this as a complete starter kettlebell library rather than a lifetime purchase.

Care, Maintenance, and Long Term Durability

Cast iron needs very little care, but it does need some. Wipe sweat off the handle after every session. Salt corrodes powder coating faster than anything else in a home gym.

Check the locking collar before each workout and again before overhead sets. Hand tighten firmly without using tools, since over torquing strips plastic threads.

Store the bell indoors. Garages with humidity swings will spot the finish over a year or two. Light surface rust sands off with fine steel wool and a thin coat of machine oil.

Yes4All offers standard warranty coverage through Amazon returns, which is shorter than the multi year coverage from REP or Bells of Steel. Keep your packaging for the first month in case a casting flaw shows up.

Final Verdict: Should You Buy It in 2026?

Last update on 2026-10-18 / Affiliate links / Images from Amazon Product Advertising API

The Yes4All Adjustable Kettlebell Set earns a confident recommendation for one specific buyer: the person starting kettlebell training in a small space on a modest budget. It gives you real cast iron, a usable 7.8 LB to 40 LB range, and a footprint you can hide under a bed.

It is not a lifetime bell. The 40 LB ceiling, the slow plate swaps, and the plastic collar put a clear limit on who stays happy with it. Strong lifters and circuit fanatics should spend more elsewhere.

Buy it if you want maximum weight variety for minimum money and floor space. Skip it if you already swing heavy or need instant weight changes. For most home users in 2026, it does the job it claims to do.

Frequently Asked Questions

How much does the Yes4All adjustable kettlebell weigh in total?

The complete set reaches 40 LB when every plate is loaded. The lightest setting is 7.8 LB, and the cast iron handle unit alone weighs 15 LB with a 5 LB base plate closing the bottom. You get seven usable weight settings in between.

How long does it take to change the weight?

Expect 20 to 30 seconds per change once you know the plate order. You unscrew the lock, swap discs on the center post, reseat the base plate, and retighten. It is slower than a dial bell but requires no tools.

Is the Yes4All kettlebell made of real cast iron?

Yes. The handle unit and weight discs are cast iron with a powder coated finish. Only the locking collar and the filler discs use plastic, which is also the part most likely to wear over time.

Can beginners use this kettlebell safely?

Yes, with two habits. Check the lock before every session and before any overhead movement. Start at a light setting and learn the hip hinge before adding plates. The wide handle and flat base make basic swings and goblet squats comfortable.

Does the kettlebell rattle during swings?

A properly tightened bell stays quiet. Rattling means the lock has loosened or a disc is seated wrong. Stop, retighten, and check the stack. Some owners report slight wobble even when tight, which is common in plate loaded designs.

Is 40 LB enough for building strength?

It is plenty for beginners and most intermediate users across presses, squats, carries, and get ups. Experienced lifters will outgrow it on two handed swings and deadlifts within a few months, since those movements tolerate much heavier loads.

What is included in the box?

You receive the cast iron handle unit, the base plate, the cast iron weight discs, the filler discs, and the locking hardware with a short instruction sheet. There is no storage rack, carry bag, or printed workout program.
