How do I Choose a Cable Machine?

While there’s a certain kind of joy in feeling a cold barbell in your hands, there’s also a special place in a lifter’s heart for that burn of a cable machine.  

A cable machine (also called a functional trainer or pulley machine) creates resistance using weights (plates or stacks) attached to a cable running through a pulley system.  

REP offers five different functional trainers. Some are stand-alone, while others attach to your power rack, but they’re all glorious in their own ways. Not sure which is the best match for you? Here’s how they compare.

Benefits of Cable Machines

Cables provide a different stimulus than free weights (dumbbells and barbells). They provide constant tension on the muscles when lifting and lowering the weight -- and tension is related to strength and muscle growth. Cables also allow you to easily work muscles through different planes of motion and angles.  

Here are some other benefits of a functional trainer:  

  • Cable exercises can be easier to perform correctly than barbell exercises, which can make them safer.  
  • They’re great for lifters of all levels.  
  • They’re super versatile for just about every muscle group.  
  • You can isolate muscle groups easily on cable machines.  
  • Selectorized machines (with weight stacks and pins) are quick to load and adjust, speeding up your workout. It’s also easy to swap out handles for different purposes.  

Types of Cable Machines

There are several different types of cable machines.  

Selectorized vs. plate-loaded: Selectorized machines use pre-set stacks of weight, adjusted by pins you stick into a hole in the plate. Plate-loaded trainers have a weight horn (or multiple weight horns) attached to the cable, and you load weight plates onto the horns to change the weight. To add weight to a plate-loaded functional trainer, you need to have separate plates.  

Ratio: A 1:1 ratio means 20 pounds on the cable creates 20 pounds of resistance for you to move. These are also called single-pulley machines. A 2:1 ratio means 20 pounds feels like 10 pounds. These are also called double-pulley machines. A 2:1 ratio is great for functional training, when you want a faster-traveling cable. Don’t mistake two single-pulley machines for a double-pulley; the resistance you will feel is different.  

Specialty cable machines: In addition to the standard cable machines, you can find two specialty types designed to target the back (although you can use them in other ways, too). These are the lat pulldown (pulley is up high) and seated row machines (pulley is low to the ground). The height of these pulleys is not adjustable. 

How to Choose a Functional Trainer?  

Unsure how to pick the right functional trainer for your home gym and personal goals? Let us make it easy for you.  

Here’s a quick look at the pros and cons of REP’s five different functional trainer options.  

FT-5000 2.0

Pros: Full, commercial-grade, stand-alone functional trainer. Features 21 different adjustment point and comes with two polymer D-handles and storage pegs to organize your attachments.  

Cons: Biggest footprint if you have limited space. 

FT-3000 2.0

Pros: The most compact, stand-alone cable machine with a greater range of motion and more height options than the original compact trainer. It also has slightly more weight than the original.  

Cons: Slightly shorter cable length than the original FT-3000.  


Lifter using the Ares functional trainer


Pros: Biggest weight capacity, minimal additional footprint, integrated lat pulldown/low row, comes with the most attachments. 

Cons: The most expensive rack-mount functional trainer, shorter cable travel than other rack-mounted options, no band pegs for resistance bands.  

Plate-Loaded Athena

Pros: High weight capacity, budget friendly (assuming you already have plates), integrated band pegs (so you can use resistance bands), Athena has the longest cable travel length of all functional trainers. The attachment itself is lightweight, baby (87lbs per unit). 

Cons: You need to own plates to add resistance, lat/low row feature not included (you must buy this separately), bigger footprint than Selectorized Athena.  

Selectorized Athena

Pros: Small additional footprint, easy to adjust weight, no plates needed, integrated band pegs, Athena has the longest cable travel length of all functional trainers.  

Cons: Lowest weight capacity for a rack-mounted functional trainer (but it does match the capacity of the FT-5000). 

Still Can’t Decide?

Here are some of the reasons you might select one functional trainer over the other.   

If you have limited space and no power rack: FT-3000 2.0 
The FT-3000 2.0, is the newest compact version of REP’s freestanding functional trainer and has the smallest footprint if you don’t have a power rack, don’t have a PR-4000/5000, or you do but don’t want to attach a cable machine to it. These trainers are small enough to fit through a standard doorway. They weigh less, too: 770lbs for the FT-3000 instead of 1,001lbs for the full-size. 

If you have limited space and a power rack: Ares 

The Ares mounts to your existing power rack. In total, it only adds 1.2”(H)x1.6”(W)x6"(D) to the PR-4000, and 1.2”(H)x5”(W)x6"(D) to the PR-5000. 

If you have limited space, a limited budget, and a power rack: Plate-Loaded Athena  

The Plate-Loaded Athena attaches to the side of your power rack, so it doesn’t add much of a footprint to your gym, but it’s more affordable than the Ares or Selectorized Athena – assuming you already have plates. Also, a lat and low row attachment isn’t included in the Athena, so it’s a good bet if you already have one, don’t want one, or don’t mind buying one separately. 

If you have limited space and don’t have a large collection of plates: Selectorized Athena  

The Selectorized Athena adds less width to your power rack than the Plate-Loaded Athena, and with a built-on weight stack, you don’t need to own (or store) plates to add weight to the cables. It does have a slightly bigger footprint than the Ares, which is also selectorized. However, if you don’t want/need an integrated lat and low row attachment (or already have one/don’t mind buying one separately), you’ll want to go with the Athena.  

If you want a functional trainer attachment with a lat pulldown/low row attachment: Ares 

The Ares is the only functional trainer you can attach to your power rack that also comes with a lat pulldown and low row feature.  

If you want a commercial-grade, stand-alone cable system with a high weight capacity: FT-5000 2.0 

If you have space for a full, stand-alone cable system that’s tough enough for a commercial gym, the FT-5000 2.0 is the mother of all. It boasts the highest weight capacity for a stand-alone functional trainer.  

If you need the most weight: Ares 

If you really need to load up the weights for the gains, the Ares has the other machines beat in terms of weight capacity. This attachment can handle 620lbs between both sides (feels like 310lbs).
