Quick Answer
The XRT65 40lb Adjustable Kettlebell is a dial-adjustable iron kettlebell that shifts between 7.8 and 40 pounds in seven increments, making it a practical substitute for a full kettlebell rack in a home gym.
It’s best for people who want one compact tool for HIIT, strength work, and physiotherapy-style training without buying five or six separate bells.
If you need weights heavier than 40 pounds or you’re training multiple people at wildly different strength levels at the same time, you’ll want a different setup.
Key Takeaways
- The XRT65 adjusts across seven weight settings: 7.8, 12.4, 17.9, 23.9, 29.9, 35.4, and 40 pounds.
- A fast dial mechanism lets you change weight in seconds without tools.
- The handle is iron; the adjustment dial and outer shell are ABS plastic.
- Overall footprint is compact at 11.02″ L x 9.84″ W x 8.27″ H, and the fully loaded unit weighs 39.8 pounds.
- Price sits at $110.65, or $27.66 every two weeks across four payments.
- It suits home gym users who want to consolidate kettlebell storage into a single unit.
- It’s not the right pick if your programming regularly calls for kettlebells heavier than 40 pounds.

What is the XRT65 40lb Adjustable Kettlebell?
The XRT65 is a single kettlebell that replaces a stack of fixed-weight bells by letting you dial the resistance up or down between 7.8 and 40 pounds.
It’s built around an iron handle connected to a selector system, with weight plates housed inside a black-and-blue ABS shell.
The core problem it solves is space and cost. A traditional kettlebell collection covering that same weight range would mean owning six or seven separate bells, each needing its own storage spot.
For anyone training at home, that’s a lot of floor space and a lot of up-front money. The XRT65 compresses that into one unit roughly the size of a large shoebox.
This kind of adjustable system also makes sense for physiotherapy and rehab settings, where a single client might need a very light bell early in a program and a heavier one a few weeks later.
Rather than stocking a full range of fixed weights, a clinic or home user can scale the same bell as capacity improves.
Key features deep dive
Seven-setting weight range (7.8 to 40 pounds)
🛒 Check Price
The XRT65 covers a wide enough span to work for both light conditioning work and heavier strength movements.
The seven increments are 7.8, 12.4, 17.9, 23.9, 29.9, 35.4, and 40 pounds, which gives roughly 5- to 6-pound jumps between most settings.
That spacing matters in practice. A jump from 7.8 to 12.4 pounds is a meaningful step up for someone doing high-rep snatches or presses, so progression happens in digestible stages rather than big leaps that stall a workout.
For reference, anyone building out a true beginner routine might start closer to the bottom of this range and work upward; our guide to a 20-minute kettlebell workout for beginners uses similar light-to-moderate loading as a starting point.
Fast dial adjustment
The fast dial is the mechanism that lets you change weight without tools, pins, or separate plates to load by hand. You rotate or set the dial to the desired marked weight, and the internal plates lock into the handle assembly.
This is the feature that actually makes the “adjustable” claim functional day to day. A kettlebell that takes two minutes and a wrench to adjust defeats the purpose in a fast-paced circuit.
With a dial system, you can move from a heavier swing set straight into a lighter overhead press set inside the same superset, which matters a lot if you’re following something like a 10-minute HIIT kettlebell workout where rest periods are short by design.
Iron handle with ABS dial and shell
The handle, the part your hand actually grips, is iron. The dial mechanism and outer housing are ABS plastic.
This split construction is common in adjustable kettlebells because it balances durability where it’s needed most (the handle) with weight savings and lower manufacturing cost in the housing.
An iron handle holds up to chalk, sweat, and repeated swinging better than a coated or plastic grip would over time.
The ABS shell, meanwhile, keeps the unit from being any heavier than it needs to be and helps contain the internal weight plates safely during fast movements like swings and cleans.
Compact footprint for storage
At 11.02 inches long, 9.84 inches wide, and 8.27 inches tall, the XRT65 takes up roughly the space of a small toolbox.
Loaded to its maximum, it weighs 39.8 pounds, just under the advertised 40-pound top setting (packaging and hardware account for the small gap).
For apartment dwellers or anyone training out of a closet or corner of a garage, this single-footprint design means you’re not stacking six kettlebells of different sizes along a wall.

Hands-on experience
Using the XRT65 day to day feels closest to using a mid-size fixed kettlebell with a brief pause between sets to reset the dial.
The iron handle has enough thickness for a secure two-hand grip during swings, and the balance point stays stable through the adjustment range, so you’re not fighting an off-center feel at lighter settings.

Where it performs well:
- Circuit training: Dropping from 23.9 to 17.9 pounds between exercises takes seconds, which keeps momentum in a timed circuit. This pairs well with structured sessions like a 15-minute HIIT workout or a 30-minute kettlebell workout.
- Progressive overload for strength: Someone building up from goblet squats to heavier swings can move through all seven settings over weeks or months without buying new equipment, which lines up with the logic in our adjustable kettlebell workouts for muscle building guide.
- Rehab and physiotherapy use: Light settings in the 7.8 to 17.9-pound range work for controlled, lower-intensity movement patterns common in physio programming.
Where it’s less ideal:
- Fast, ballistic movements like snatches at the top weight setting put more stress on the dial mechanism than a one-piece cast iron bell would experience, simply because there are moving internal parts.
- Group classes or shared household use (multiple people training back-to-back at very different weights) means more frequent dial changes, which adds friction compared to everyone grabbing their own fixed bell.
Pros & cons
✅ What we love
- Seven weight settings cover a genuinely useful range for both beginners and intermediate lifters.
- The fast dial mechanism changes weight quickly enough to use in timed circuits.
- Iron handle construction holds up well to regular gripping and chalk use.
- Compact dimensions mean one storage spot instead of a rack of bells.
- Flexible payment option ($27.66 every two weeks for four payments) lowers the up-front cost barrier.
❌ What could be better
- 40 pounds is the ceiling, so advanced lifters needing heavier loads will outgrow it.
- ABS components in the dial and shell are not as bomb-proof as a one-piece cast iron design under heavy ballistic use.
- Single-user design makes rapid multi-person use less convenient than owning separate fixed bells.
Who should buy this?
The XRT65 fits home gym owners who want one kettlebell to cover a progression from light conditioning work up to moderate strength training, without buying and storing a full set. It’s a strong match for:
- Beginners who aren’t sure which weight they’ll settle into and want room to grow, similar to the audience for our 20lb kettlebell guide.
- People doing HIIT-style circuits at home who need to change loads between exercises quickly.
- Anyone using kettlebells for physiotherapy or recovery work where load needs to increase gradually over a program.
- Space-limited households (apartments, shared gyms, garages with limited storage) who don’t want a rack of bells.
Who should skip this?
If your training regularly requires weights above 40 pounds, the XRT65 won’t keep up and you’ll need a heavier fixed bell or a different adjustable system with a higher ceiling.
Advanced lifters doing max-effort swings, heavy Turkish get-ups, or strongman-style kettlebell work will hit this ceiling quickly.
It’s also not the best choice for households where several people train at the same time at very different weights, since everyone would be waiting on the same dial. In that scenario, a small set of fixed-weight bells, or even checking out options compared in our adjustable kettlebell brands comparison, may serve better.
How to get the best deal
Buying through the installment option ($27.66 every two weeks for four payments, totaling $110.65) spreads out the cost without adding interest, which is useful if you’d rather not pay the full amount up front.
🛒 Check Price
Watch for seasonal sales around major shopping periods, since adjustable kettlebell pricing tends to fluctuate with broader home fitness equipment promotions.
It’s also worth comparing the per-pound cost against a basic fixed-weight set; if you already know you’ll stick to one or two weights long-term, a simpler set might be cheaper, but the XRT65 earns its price back in storage savings and workout flexibility.
FAQ
Is the XRT65 kettlebell good for beginners?
Yes. The lowest setting (7.8 pounds) is light enough for learning proper form on swings and presses, and the gradual increments let beginners add weight without jumping straight to an intimidating load.
Can I use the XRT65 for heavy strength training?
It works for moderate strength training up to 40 pounds, but lifters who need heavier loads for squats, deadlifts-style movements, or heavy swings will need a bell with a higher weight ceiling.
How long does it take to change the weight on the XRT65?
The fast dial mechanism is designed to adjust weight in a few seconds, which is fast enough to use between exercises in a timed circuit without losing much rest time.
Is the ABS plastic on the dial durable?
The ABS shell and dial are built for standard home use and moderate-intensity training. Very aggressive ballistic movements at the top weight setting put more wear on these components than they would on a solid cast iron kettlebell.
What’s the difference between this and a fixed-weight kettlebell set?
A fixed-weight set requires owning and storing multiple bells, one for each weight you want to use, while the XRT65 condenses that range into a single adjustable unit. Our adjustable kettlebell vs dumbbell for beginners guide covers a related comparison if you’re weighing adjustable options against other equipment types.
Does the XRT65 work for physiotherapy use?
Yes. The lighter settings in the 7.8 to 17.9-pound range are suitable for controlled rehab-style movements, and the ability to increase load gradually on the same unit fits typical physiotherapy progression.
Final verdict
The XRT65 40lb Adjustable Kettlebell earns its place in a home gym by solving a real problem: covering a wide, useful weight range without needing a rack of separate bells.
The fast dial system is the standout feature, and it’s precise enough to trust during timed workouts and gradual rehab progressions alike.
The tradeoff is a 40-pound ceiling and ABS components that, while functional, aren’t quite as bulletproof as solid cast iron under heavy ballistic loading.
For beginners, space-conscious home gym owners, and anyone running structured programs that call for gradual load increases, this is a sensible, well-priced pick. Lifters chasing heavier max loads should look elsewhere.
