A comparison by Speediance
Gym Monster 3, AEKE S1 Pro or Innodigym OMNI X1 Pro? Start with the dimensions, the screen and the ownership costs. Here is where we think GM3 deserves a closer look.
Why we would choose GM3
These are comparisons of published hardware specifications. Competitor figures refer to European models; the table identifies the UK source where used. Confirm the specification and availability for your country. GM3 specifications may change before general availability.
≈16%
Calculated from published width × depth: GM3 69 × 37 cm = 0.2553 m²; AEKE S1 Pro 71.5 × 42.5 cm = 0.3039 m². About 16% less floor area for the folded machine. This excludes accessories and workout clearance; it is not a claim of the smallest footprint among all three models.
23.8″
GM3 lists a 23.8-inch touchscreen, compared with Innodigym’s 54.6 cm diagonal (about 21.5 inches). AEKE S1 Pro has the larger screen of these three at 27 inches. Diagonal size alone does not establish display quality.
No mandatory subscription
The current GM3 offer includes the on-machine workout library, training plans and workout history. Advanced AI features require optional paid Wellness+. This describes the Speediance offer; it does not imply that competitors require a subscription.
Figures are manufacturer specifications, not our measurements. Storage space is different from exercise space. No overall winner is claimed. Sources checked: 2026-10-25.
01 / Specifications
Figures below come from the linked manufacturer pages. Descriptions, measurement methods, accessories and configurations may differ. A published maximum is not a measurement of equivalent real-world performance.
Hardware references: Speediance product page, AEKE EU FAQ and Innodigym Europe product page. These references do not confirm local sale, delivery or electrical configuration in your country.
On a small screen, swipe the table sideways to see all three models. You can also focus the table and use the arrow keys.

Dimensions describe the machine, not the space needed to exercise. Folded storage orientations differ; do not rank the three footprints without checking the full setup.
This table does not establish current stock, delivery eligibility, prices, included accessories or regional warranty coverage. Confirm these details with the seller before ordering.
02 / Before you buy
Your room, preferred exercises and purchase terms matter alongside the specifications.
Request the operating footprint, ceiling and wall clearances, access requirements and the space needed for a bench and accessories. A stored footprint is different from the space needed during exercise.
Confirm the model, package, accessories, software access, any recurring charges, total delivered price and the return conditions for your address.
Ask for the seller's identity, written warranty terms, service arrangements and parts process. Check these for the country where the equipment will be used.
We use the manufacturer's own product information for the named model. Linked pages may change after the check date. Missing or unclear details are identified rather than inferred. Contact the manufacturer or seller for confirmation.
