ATX® Back - Rowing Machine - Back-Contractor RMX-760

The ATX Back-Contractor RMX-760 (SKU ATX-RMX-760) is a plate-loaded, chest-supported back/row machine from ATX Fitness, the strength-equipment brand of Germany’s Aerobis. Instead of one bilateral pulling bar, it uses alternating, independently-operating lever arms — a unilateral, iso-lateral design meant to work each side of the back on its own so a stronger side can’t compensate for a weaker one. The 360° swivel handles let you vary grip angle mid-set, and both the seat and the pivoting chest pad adjust to fit different torso heights. Specs are consistent across every German, Swiss, and Australian listing we found: roughly 1445 x 990 x 1250 mm, 65 kg machine weight, a 250 kg (551 lb) load rating on 50 mm plate posts, and certification to EN 20957 I.II.IV Class S — the studio/commercial-use standard.

Be clear-eyed about what this page can and can’t tell you. This is a genuinely thin niche listing: we found no independent editorial review, no owner video, and no community thread (Reddit, forums) discussing this machine anywhere. GymRadar’s own aggregate page confirms it — 0 submitted reviews (Performance, Build Quality, and Value all show 0.00/5) and just 1 tracked gym owner worldwide. Everything below is synthesized from manufacturer and retailer spec sheets, not from anyone who has actually put hours on the machine, so treat the design as promising on paper rather than proven in practice.

Retailers don’t even agree on the fine print. Warranty terms range from 5-year (megafitness.shop, Sam’s Fitness AU) down to 2-year (motionsports.de), with JK-Sportvertrieb’s B2B listing stating no term at all. Retail pricing spans multiple currencies and tax treatments — roughly €599 incl. VAT at German retail, €503 excl. VAT at a German trade/B2B storefront, and $1,095 AUD in Australia — with no single reliable US-dollar price, so no price or buy link is set on this page; see the manufacturer/retailer links below for current pricing in your region.

What is a Machine?

What a strength machine is

A strength machine guides the resistance along a fixed path so you can train a movement safely, often without a spotter. The main types: selectorized (pick weight with a pin), plate-loaded (add your own plates for a heavier ceiling and better feel), and functional trainers / cable machines (adjustable pulleys for dozens of exercises).

Machines vs. free weights

Machines shine for isolation, safety, and high-rep hypertrophy, and for training hard alone. Free weights build more stabilizer strength and carry over better to sport. Most well-rounded home gyms use a rack and barbell as the core and add one machine — often a cable/functional trainer or a lat-pulldown/row — to fill the gaps.

The sub-types worth knowing

“Machines” covers several categories that barely compete with each other: GHDs for hamstring and posterior-chain work, belt squats for loading the legs without the bar on your back, leg press / hack squat combos for heavy quad volume, reverse hypers for posterior-chain work and lower-back decompression, cable towers and functional trainers for pulling movements, and row machines. Pick the one that fills a gap in what your rack and barbell already do. Almost nobody needs two.

Space and standalone vs. rack-mounted

Most of these come in a standalone version and a cheaper rack-attachment version. The attachment saves floor space and money, but often gives up stability or range of motion — a tradeoff worth checking on the specific product rather than assuming, since it varies a lot between designs.

A note on ratings

Machine listings frequently show a manufacturer’s own on-site rating, which runs high (4.7–5.0 is typical) and sometimes pools reviews across a whole product family rather than the exact configuration you’re buying. Where we have independent hands-on coverage, our summaries anchor to that instead, and say so on the product page.

The RMX-760’s design is legitimate on paper: independent, alternating lever arms for iso-lateral back training, 360° swivel grips, an adjustable pivoting chest pad, a 250 kg load rating, and EN 20957 commercial certification from an established German strength brand (ATX/Aerobis). But that’s the entire case for it — there is no independent review, no owner video, and no community discussion of this machine anywhere we could find, and GymRadar’s own aggregate page shows 0 submitted reviews and only 1 tracked gym owner worldwide. This score reflects a well-specified, plausibly solid commercial-grade machine with essentially no real-world track record behind it; treat it as a reasonable bet for a niche EU/AU buyer rather than a proven pick.

+Functionality: alternating, independently-operating lever arms train each side of the back separately, addressing muscular imbalances a bilateral row bar can mask
+Functionality: 360° swivel grips plus a height- and angle-adjustable, pivoting chest pad let you dial in grip angle and torso position for a joint-friendly pulling path
+Build: robust square-tube steel frame, chrome-plated knurled grips, and EN 20957 I.II.IV Class S commercial/studio certification with a 250 kg (551 lb) load rating
+Value: EU retail pricing (roughly €500-600) undercuts many commercial iso-lateral chest-supported rows, though it's not sold in the US

−Evidence / track record: zero submitted reviews anywhere we could find — GymRadar lists 0.00/5 across Performance, Build Quality, and Value, with only 1 tracked gym owner and no independent editorial or owner-video coverage of this SKU
−Availability: no dedicated US manufacturer presence; buyers outside the EU/AU face import/freight costs, and Sam's Fitness AU listed it out of stock at fetch time
−Documentation: retailers disagree on the warranty term (5-year vs 2-year vs none stated) and even on shipping weight (65 kg vs a 74.50 kg figure elsewhere on one listing), so the spec sheet itself isn't fully reconciled across sources
−Assembly: ships disassembled with no third-party assembly or long-term-use photos beyond manufacturer renders
