Single vs Dual Cable Machine for a Home Gym
Single-stack vs dual-stack cable machines for home: what each does well, space, price and which to buy, with REP's Athena and Arcadia as examples.
The short answer
Buy a dual cable machine (a functional trainer) if you want flyes, crossovers and two-handed movements with independent arms. Buy a single cable station if you mainly want lat pulldowns, rows, pushdowns and curls, or want to add one to a rack now and a second later.
Single cable vs Dual cable at a glance
| Exercise variety | Dual Crossovers, flyes, and both arms working independently. |
|---|---|
| Price | Single One REP Athena is about $950; a dual-stack Arcadia is about $2,200. |
| Space | Single A single column bolts to a rack and adds only a few inches. |
| Lat pulldowns and rows | Tie Both do them; a 1:1 single stack feels heavier than a 2:1 dual stack. |
| Upgrade path | Single Add a second rack-mounted column later and you have a dual setup. |

What a single cable station does
A single column with one weight stack handles lat pulldowns, seated rows, triceps pushdowns, curls, face pulls and single-arm work. Mounted to a rack, like the REP Athena, it adds only a few inches and costs about $950.
What a dual cable machine adds
Two independent stacks let you do chest flyes and crossovers, press with both arms independently and train each side at the same time. The REP Arcadia is a compact example at about $2,200. REP’s pitch for dual stacks is that both hands aren’t fighting to move the same stack. Not everyone wants that: in one r/GarageGym thread, a Rogue fan says they hate unilateral pulldowns and rows and choose a single pull every time.
Pulley ratio matters
Most dual machines use a 2:1 ratio (the stack feels half as heavy), while many single lat stations are 1:1. If heavy pulldowns are your priority, a 1:1 single station is better; see our best lat pulldown machines.
Which should you buy?
Start with a single stack if budget or space is tight, especially if it can mount to your rack and you can add a second later. Go straight to dual if you want the full range of cable training. See our best functional trainers and best cable machines.
FAQ
Is a dual cable machine worth it?
Yes, if you'll do flyes, crossovers and unilateral work, which are where a dual setup shines. Owners on r/GarageGym say cables change how they train. If you mostly want pulldowns and rows, a single stack is enough and costs less than half as much.
Why do dual cable machines feel lighter?
Most dual machines use a 2:1 pulley ratio, so 170 lb on the stack feels like 85 lb, in exchange for twice the cable travel. Single lat stations are often 1:1, so the stack feels like its full weight.
Can I do lat pulldowns on a dual cable machine?
Yes. Most functional trainers include a lat bar and a pull-up bar, but the 2:1 ratio limits how heavy you can go, and few have a thigh pad. Stronger lifters often add a dedicated 1:1 lat station.
