ARX is worth considering if you have the money set aside, you value time more than the feel of a barbell, and you want strength training you can't skip because it sits 21 or 37 square feet from your desk. The ARX Alpha at $43,000 fits the busy professional and the in-season athlete who want 6 guided movements and the shortest session. The ARX Omni at $46,000 fits the home-gym owner replacing a room of equipment with one machine. If you enjoy free weights and have the hours for them, keep the barbell. ARX wouldn't argue: in its own materials it concedes that barbells win on cost and track record and teach you to balance and stabilize real loads.
ARX sells 2 machines, and the pitch for both is a full-body strength session in about 15 minutes, twice a week, with a motor in place of a weight stack and a dashboard that records the force of every rep. Both are built for a narrower profile than the marketing suggests, and the buyers ARX itself names are the ones they fit. Prices and specs below come from ARX's published machine page as recorded in our catalog, verified 2026-09-17, with footprint and weight rechecked against that page on 2026-09-30.
Quick answer
- Busy professional with 21 square feet to spare: the ARX Alpha at $43,000, 6 guided movements on a sled and the fastest ARX session.
- Home-gym owner replacing a room of equipment: the ARX Omni at $46,000, 17 cable exercises including belt squat, deadlift and Romanian deadlift.
- Athlete in season, or a studio running clients back to back: the ARX Alpha at $43,000, the machine ARX designed to be easiest to learn at any skill level.
- Lifter who enjoys free weights and has the hours: keep the barbell. ARX itself concedes that barbells win on cost and track record.

Both machines are designed and manufactured in Austin, Texas, ship with a complimentary 1-year warranty, a typical 2 to 4 week lead time and the ARX Certified Course, and sell through a Talk to ARX call with no checkout. We haven't tested either machine, and every outcome figure here is ARX's, attributed to ARX.
What ARX is actually selling
In place of a weight stack, a computer-controlled motor pushes back with exactly the force you produce at every point in the rep. ARX's argument is that this loads the lowering, or eccentric, phase in a way it says weights cannot, and that it removes the decision of how much to load: the machine matches whatever you give it, so every rep is as hard as you make it.
On the Alpha that resistance rides on a guided sled that keeps each rep on one path across 6 exercises: leg press, chest press, row, calf raise, torso flexion and torso extension. On the Omni it runs through a cable system with clip-on handles and attachments, which is how one machine covers 17 exercises: belt squat, deadlift, Romanian deadlift, hamstring curl, calf raise, horizontal press, incline press, decline press, overhead press, pec fly, pulldown, pullover, row, high pull, shrug, biceps curl and triceps pressdown. ARX says the Omni does the work of 10 or more machines.
The software is the other half of the product, and you can't skip it: a separate subscription, identical on both machines, at $200 a month for home use or $400 a month commercial, with lifetime licenses available at a price that isn't in our verified data. It programs the session, and ARX says any rep scheme runs on it: standard, negative-only, positive-only, static, time-under-tension and partial-range sets, with adjustable rep speed, set, pause and rest times. It records total force, max force in both the concentric and eccentric directions, rep speed, range of motion, intensity, exercise time and fatigue to an online dashboard. ARX says all of its machines can be programmed and controlled by the software so you can train alone, and personal onboarding through ARX Academy comes with the machine.
Whose numbers the 15 minutes rests on
The schedule in the title is ARX's: about 15 minutes, full body, twice a week, with the note in ARX's own specs that most users train one to two times a week. ARX leads with these outcome figures: twice the muscle gain, 90 percent greater strength gain, 2.5 times the fat loss and 3.5 times the cardiovascular improvement in 72 percent less training time. They come from a 12-week study at Western Colorado University commissioned by the American Council on Exercise in 2021 and later published in the International Journal of Research in Exercise Physiology. ARX reports that its group trained twice a week for 15 minutes against a moderate-intensity weight training group at 45 minutes 3 times a week. ARX also cites a 2023 Sports Medicine review and its role in the XPRIZE Healthspan training arm, which has not reported results.
Those are the brand's figures from the brand's cited study. We haven't tested an Alpha or an Omni, and one commissioned 12-week study gives you a reason to take the schedule seriously and no proof that it will hold for you. The line ARX uses about being trusted by Tony Robbins, Dave Asprey and Ben Greenfield is ARX's, not ours.
Who ARX names, and whether the schedule fits them
ARX is unusually specific about its buyers, so read the profiles against your own week instead of the study.
For the Alpha, ARX names busy professionals, athletes in season and studios running clients back to back. The common thread is a session that has to be short and hard to get wrong. With 6 movements on a guided sled there's no bar path to learn and no plates to change, and ARX calls the Alpha its easiest machine to learn at any skill level, its most space-efficient, and, in its own words, faster through all of its exercises than the Omni. If your strength training fails because the 45-minute version never happens, a 15-minute version 21 square feet from your office is a different proposition, and that's the buyer this machine was designed around.
For the Omni, ARX names founders building a studio around one machine, clinics that need movement-specific loading, and home-gym owners replacing a room of equipment. That last profile is the home buyer to take seriously. If you already own a rack, a cable stack, a leg press and a bench and you're tired of the room they take, the Omni's 17 exercises in 37 square feet are the consolidation argument, and it's the only ARX machine with belt squat, deadlift and Romanian deadlift on the list.
The profile ARX doesn't name is the person who likes lifting. Nothing about a motor-matched sled replaces the skill and the feel of a loaded bar, and ARX doesn't claim it does.
What ARX itself concedes
The most useful line in ARX's own materials is the concession: barbells win on cost and track record, and they teach you to balance and stabilize real loads. Read that as the boundary of the product. ARX argues that for a buyer whose constraint is time, or space, or loading a hard rep alone without a spotter, a motor that matches your output is a better fit than iron. If your constraint is money, the concession settles it.
The ownership terms concede more. The software license is non-transferable, and without an active license the machine won't run at all: no workout and no force data. ARX reviews every serial number individually before it will sell a new license to a resale buyer, not every machine qualifies, the warranty ends when the machine changes hands, resale buyers must complete ARX Certified Training before use, and moving the machine requires consulting ARX. ARX strongly discourages third-party purchases and keeps a waitlist for used machines it sells directly. A $43,000 machine with a thin resale path is a different financial decision from a rack you can sell on a weekend.
The real cost of owning one at home
The hardware price is the number ARX publishes: $43,000 for the Alpha and $46,000 for the Omni, both verified 2026-09-17. ARX quotes about $1,200 a month through third-party lenders and doesn't finance in-house; the lender's term isn't in our verified data, and a lender payment is never the price. Software adds $200 a month for home use, which is $2,400 a year on top of the hardware for as long as you own it, unless you buy a lifetime license at a price ARX doesn't publish on the page we verified.
Then there's the room. Both machines need 110V on a dedicated 20A circuit or 220V on a dedicated 15A circuit, ship with a power supply set to your outlet voltage at install, and are not compatible with GFCI outlets per ARX. For most homes that's an electrician visit before delivery, at a cost that isn't in our verified data. ARX's machines page gives the Alpha 21 square feet and the Omni 37 in their headings; its comparison table gives the Alpha 24 square feet, 34 by 103 by 59 inches, and the Omni 38 square feet, 42 by 129 by 90 inches, at about 700 pounds each. ARX doesn't state which dimension is which, so confirm ceiling height and the doorway route on the Talk to ARX call. Delivery and install are arranged with ARX, and the typical lead time is 2 to 4 weeks from order.
Where the ARX Alpha gives ground
The Alpha gives up 11 exercises and the cable system's grips and attachments. Its list has no belt squat, deadlift, Romanian deadlift, overhead press or pulldown. The 6 guided movements cover a full-body session the way a machine circuit does, on one fixed path per exercise, which removes the balancing and stabilizing work ARX itself says barbells teach. For a busy professional that's the point; for anyone who wants variety or free-path movement, it's a limit. It's also a $43,000 machine that does 6 things. If you find yourself wanting a seventh, the Omni is $3,000 more and 16 square feet larger, and nothing in our verified data describes an Alpha-to-Omni upgrade path.
Where the ARX Omni gives ground
The Omni gives ground on the 2 things the Alpha is best at. It's bigger, at 37 square feet, closer to a small room than a corner, though ARX lists both machines at about 700 pounds. And ARX itself says the Alpha is faster through its exercises and easier to learn; 17 cable movements with clip-on attachments mean more setup between exercises and more to get right, and a session that drifts past 15 minutes is one the schedule buyer starts skipping. The Omni is for a buyer who'll use the library. If 6 movements would do, you're paying $3,000 and 16 square feet for a list you won't finish.
Alpha or Omni, if you have settled on ARX
Adaptive resistance is the technology both share, not a model name, and the software and what it measures are identical on both. The choice is exercise range against footprint. If the full library matters, and especially if belt squat, deadlift or Romanian deadlift are non-negotiable, it's the Omni at $46,000 in 37 square feet. If 6 guided movements and the smallest ARX footprint are the point, it's the Alpha at $43,000 in 21 square feet. Both run the same $200 a month home software, so the ongoing cost doesn't separate them.
Verdicts by buyer type
- Busy professional whose training keeps not happening: the ARX Alpha, with 6 movements, one path each, and ARX's shortest session, 21 square feet from wherever you work. The schedule fits because it removes the reasons to skip.
- Athlete in season: the Alpha again, for the same reasons, with the caveat that ARX's claim about loading the eccentric phase is ARX's; run it past your own coach before it replaces anything in your program.
- Home-gym owner replacing a room of equipment: the ARX Omni, with 17 exercises, the only ARX with belt squat and deadlift, and a footprint that consolidates a rack, a cable stack and a leg press into 37 square feet.
- Founder building a studio, or a clinic that needs movement-specific loading: the Omni, budgeted for the commercial software at $400 a month instead of $200.
- Lifter who enjoys free weights and has the hours: keep the barbell. ARX concedes this one. Our all-in-one home gym comparison and the Best Home Gym Equipment guide cover racks and cable trainers at a fraction of the price.
- Buyer who wants to own the machine outright with no monthly bill: neither, unless the lifetime license price ARX quotes on the call works for you. Our roundup of smart home gyms without a subscription is the alternative shortlist.
- Bargain hunter eyeing a used unit: pause. The license doesn't transfer, the machine won't run without one, and ARX reviews every serial number before selling a new license. Have ARX verify the serial before money moves.
Bottom line
Buy an ARX if your binding constraint is time or space and you have $43,000 to $46,000 plus $200 a month set aside: the Alpha for the shortest session and the smallest footprint, the Omni if it's replacing a room of equipment. Either one turns strength training into a 15-minute appointment you can keep, on ARX's schedule and with ARX's cited evidence behind it. Skip it if your constraint is cost or you like the bar in your hands; ARX's own concession that barbells win on cost and track record is the answer. Before the call, read the ARX brand page, and ask about the lifetime license and the dedicated circuit first.
Is ARX worth it for a home gym?
For the buyers ARX names, yes: busy professionals, in-season athletes and home-gym owners replacing a room of equipment, with $43,000 to $46,000 plus $200 a month in software set aside. For a lifter who enjoys free weights and has the hours, no, and ARX itself concedes that barbells win on cost and track record.
How much does an ARX machine really cost to own at home?
The published hardware prices are $43,000 for the Alpha and $46,000 for the Omni, verified 2026-09-17. Software is a required separate subscription at $200 a month for home use, which is $2,400 a year. ARX quotes about $1,200 a month through third-party lenders, but that's a lender payment, and the hardware figure is the price. Budget an electrician for the dedicated circuit.
Does 15 minutes twice a week on an ARX actually work?
It rests on one study ARX cites and we haven't replicated: a 12-week Western Colorado University study commissioned by the American Council on Exercise in 2021. ARX reports its group trained 15 minutes twice a week against 45 minutes 3 times a week and came out with 2 times the muscle gain and 90 percent greater strength gain. Those are ARX's figures, not ours.
What space and power does an ARX need at home?
The Alpha needs 21 square feet and the Omni 37 per ARX's headings, or 24 and 38 per its comparison table, and each weighs about 700 pounds. Both need 110V on a dedicated 20A circuit or 220V on a dedicated 15A circuit, and ARX states its machines are not compatible with GFCI outlets. ARX arranges delivery and install, with a typical 2 to 4 week lead time from order.
Can I save money by buying a used ARX from a third party?
Rarely, and ARX strongly discourages it. The software license is non-transferable and the machine will not run without one, so a used $43,000 Alpha or $46,000 Omni only runs if ARX sells a new license. ARX reviews every serial number, not every machine qualifies, the 1-year warranty ends on transfer, and resale buyers must complete ARX Certified Training. Have ARX verify the serial before money moves.
