1. Adjustable FID bench
What it is: a flat, incline and decline bench that replaces the stock bench. The stock bench is fine for pressing, but a dedicated FID bench unlocks incline presses, decline work and seated shoulder movements, which is the single biggest jump in exercise range you can buy for a Gym Monster.
Who needs it: anyone who presses or does seated cable work. It is machine agnostic, so it carries over from Gym Monster 1 to 2 and 2s untouched. Expect $120 to $300 for something sturdy enough to load properly.
What to watch out for: footprint. Look for a compact base that fits inside the Speediance platform area, because a wide commercial base will fight the frame. A commercial grade FID bench such as the Rep Fitness AB-3000 or a folding Bowflex SelectTech bench both balance stability and footprint well.
2. Platform extension
What it is: extra standing surface added to the front of the machine, so your feet stay on a level, stable base instead of half on the platform and half on the floor. It is one of the two accessories worth buying before anything else, alongside the bench, because everything else you do is only as steady as what you stand on.
Who needs it: anyone pressing, squatting or working with a bench, and anyone who finds themselves stepping off the platform mid-set. Like the bench, it is machine agnostic and carries over between Gym Monster 1, 2 and 2s.
What to watch out for: floor space and whether the extension is level with the platform it joins. Full detail on who actually benefits, which exercises need it and what the alternatives are is in Is the Speediance platform extension worth it?
3. Tricep rope
What it is: the cheapest attachment that meaningfully changes a workout. A rope gives you a free wrist path, so pushdowns finish properly and face pulls track where they should instead of being limited by a fixed handle.
Who needs it: anyone training arms, rear delts or upper back. At $10 to $30 it is close to an impulse buy, and a standard carabiner or clip fits the cable on Gym Monster 1, 2 and 2s with no adapter.
What to watch out for: the ends. Get a rope with rubber end caps so the cord does not fray where your hands grip hardest, and pair it with a quick-change carabiner so you can swap attachments mid-workout instead of unthreading everything.
4. Handles and bars
What it is: the rest of the cable attachment set. Single D-handles for unilateral work, and a short bar for rows and curls. The included handles cover the basics, but two or three extra pieces expand what the Gym Monster can do far more than any single expensive purchase.
Who needs it: anyone who wants more variety for arms, back and shoulders. Prices sit at $10 to $30 per attachment, and standard carabiner and clip attachments fit Gym Monster 1, 2 and 2s alike.
What to watch out for: buying the whole wall of attachments at once. Most owners end up using two or three regularly and leave the rest in a box, which then becomes a storage problem. Buy the ones that match exercises already in your programme.
5. Ankle straps
What it is: padded cuffs that clip your ankle to the cable. They open up glute kickbacks, hip abductions and hamstring curls, which is the fastest way to turn the Gym Monster into a lower body station rather than a press and pull machine.
Who needs it: anyone doing lower body or mobility work. They cost $15 to $40 and work identically on Gym Monster 1, 2 and 2s, because they attach to the cable rather than to anything model specific.
What to watch out for: build quality, since this is the one attachment that pulls against a joint. Look for reinforced D-rings and thick neoprene padding. Thin cuffs dig in under load and you will quietly stop using them.
6. Extension straps
What it is: cable extenders that add reach. Some movements simply need more travel than the stock cable gives you, and an extension strap buys that length without changing anything about how the machine works.
Who needs it: anyone who has found the stock cable too short for a movement they want to do. If that has never happened to you, skip it for now. Price is $15 to $40, and the strap is compatible with Gym Monster 1, 2 and 2s.
What to watch out for: the rated load. This is a part that sits between you and the full weight of the machine, so check the rating before buying and do not treat a light webbing strap as a heavy pulling accessory.
7. Dip belt
What it is: a loading belt that anchors heavier work to the cable through your hips instead of your hands. It is the most specialised item on this list, which is why it sits below the straps rather than above them.
Who needs it: lifters adding load to bodyweight style movements, or anyone whose grip gives out before the target muscle does. It runs $15 to $40 and fits Gym Monster 1, 2 and 2s the same way the other straps do.
What to watch out for: buying it too early. A dip belt only earns its place once your programme already includes movements that load through the hips. Until then the money is better spent on the bench or the platform extension.
8. 3D printed bench clip, barbell holder and hooks
What it is: two MakerWorld designs that make the machine noticeably tidier. The Speediance Bench Clip for Gym Monster keeps the bench positioned neatly, and the Gym Monster Barbell and Accessory Holder stores the barbell on the frame and adds hooks for extra accessories.
Who needs it: owners with a small home gym footprint who want everything within reach. It is the best value per dollar on this list: a few dollars of filament if you have a printer, or roughly $15 to $40 through a printing service.
What to watch out for: fitment. Printed parts are the one category on this list that can be model specific, so confirm Gym Monster 1, 2 and 2s support in each listing before you start a print.
The STL is free on MakerWorld: Speediance Gym Monster 2 Multi Clip.
9. Accessory rack and storage
What it is: Speediance sells an official accessory rack, made for the Gym Monster, Gym Monster 2, Gym Monster 2s, Gym Monster 3 and Gym Monster 3s. It is somewhere to put the ropes, handles, straps and belts once you own more than two of them, and the reason people stop using attachments is almost always that they are in a box on the floor rather than on a hook at arm's length.
Who needs it: anyone past the third attachment. Besides the official rack, the options run from wall hooks and a pegboard to a printed holder on the frame, a rolling cart, or a shelf beside the machine. Which one fits depends entirely on your room, not on your machine.
What to watch out for: drilling into a wall you do not own, and racks that hold your attachments but not the barbell. The full breakdown is in Speediance accessory rack and storage: 6 ways to organize Gym Monster attachments.
10. Speediance Pilates Set (bands and platform extension)
What it is: the Speediance Pilates Set, which pairs bands with the platform extension. The platform extension is sold as part of this set today, so the set is how you get that part.
Who needs it: owners who train Pilates on the Gym Monster, and owners who want the platform extension.
What to watch out for: the contents and the price, both of which are worth confirming with Speediance before you order.
GMVoice handles the band side by voice: Add Band, Remove Band and Set Bands are in the GMVoice voice command list.
2 accessories to skip (or wait on)
A Bluetooth control ring
Rings run out of battery, disconnect, and are hard to press under heavy load, which are exactly the moments you need control. It is one more thing to charge on its own schedule for a job your voice already does. If you want hands-free control, put the money there instead.
A second set of cable attachments
The wall of handles looks appealing, but most owners settle on a rope, a pair of D-handles and a short bar. Buying a second set of specialised grips before you know which movements you actually repeat every week turns $10 to $30 items into a storage problem you then have to solve.
Software that makes the hardware better
GMVoice replaces the reach for the screen with a spoken command: say it and the weight changes or releases, without taking a hand off the bar. Voice Guard keeps the machine from acting on stray speech, so a conversation mid-set does not turn into a weight change.
GM Manager is a free web app that opens your Speediance account in any browser, so you can build workouts, schedule them and review history on a full-size screen instead of the tablet. The full walkthrough is in Plan Speediance workouts on your laptop.
Gym Monster 1 vs 2 vs 2s: which accessories carry over?
Good news for upgraders: almost everything here is machine-agnostic. Benches, platform extensions, floor mats, ropes, handles, straps and belts work the same across Gym Monster 1, 2 and 2s because they attach to the cable or sit on the floor, not to model-specific ports. The software carries over too: GM Manager runs in any browser, and GMVoice supports all three machines on both iOS and Android. The only thing to double-check is 3D-printed parts, so confirm fitment in each MakerWorld listing.
Speediance accessories FAQ
What accessories does the Speediance Gym Monster need first? For most people the priority order is a solid adjustable bench, a platform extension or floor mat for a stable base, then cable attachments and straps to expand exercise variety.
Do Gym Monster 2 accessories fit the Gym Monster 1? Yes. Benches, mats, cable attachments, straps and belts are interchangeable across Gym Monster 1, 2 and 2s. Only 3D printed parts may be model specific, so check each listing.
Are there official Speediance accessories? Speediance sells some first-party add-ons, but many of the best-value upgrades (benches, ropes, straps, mats) are standard third-party gym gear that simply clips to the cable or sits on the floor.
Where can I buy Speediance accessories? It depends on the item. First-party add-ons come from Speediance itself, while benches, ropes, handles, straps, belts and mats are ordinary gym gear you can buy from any strength equipment retailer. The 3D printed parts in this guide are published as free designs on MakerWorld, so you print them yourself or send the file to a printing service.
Do third-party attachments fit the Speediance cable clips? In practice yes. Standard carabiner and clip attachments fit the Gym Monster cable, which is why a tricep rope, D-handles or a short bar bought from any gym supplier work on Gym Monster 1, 2 and 2s. Check the rated load on anything that carries weight, especially extension straps.
Is there an official accessory rack for Speediance? Yes. Speediance sells an official accessory rack, made for the Gym Monster, Gym Monster 2, Gym Monster 2s, Gym Monster 3 and Gym Monster 3s. The alternatives are also documented here: a 3D printed barbell and accessory holder that mounts on the frame and adds hooks, plus wall hooks, a pegboard, a cart or a shelf next to the machine.
The bottom line
Start with the accessories that add the most training value, a sturdy bench and a stable platform, then layer in cable attachments and straps as your routine grows. Plan those sessions on the web with GM Manager, and if there's one upgrade that changes how every set feels, it's hands-free control: GMVoice lets you change or release weight by voice instead of reaching for the screen mid-set.
