PRx Performance Build Limitless Halo Arms Review

This product was in-house tested by Michael at The Jungle Gym Reviews.

These lever arms offer exceptional adjustability, smooth rack movement, and a level of control most standard lever arms can’t touch. The tradeoff is price and complexity—many of the premium features won’t matter unless you actually use them. They’re best for experienced home gym owners trying to replicate machine patterns in limited space. If you just want basic lever arm functionality, this is likely more than you need.

My Real-World Experience

These are not simple lever arms, and that’s obvious the moment you install them. Everything about the Halo Arms feels intentional—from the roller system to the adjustable stop brackets to the locking mechanisms.

The rollers are honestly one of the standout features. Even though each arm is heavy, the knurled handles and roller design make sliding them up and down the rack surprisingly manageable. Compared to other lever arms I’ve used—including DIY Vendetta-style setups and older roller designs—these move smoother and feel purpose-built rather than adapted.

The adjustable stop bracket is where the real functionality lives. Instead of the arm just falling to its lowest point like traditional lever arms, you choose exactly where it starts and stops. That matters a lot when you’re setting up presses, rows, or anything where consistent starting height affects the movement. There’s also a true locking position, which opens up options like dips or pull-ups directly from the arms without worrying about movement.

The swivel system is well-executed from a quality standpoint. UHMW contact points prevent metal-on-metal wear, and switching between locked and free-swinging modes is straightforward. That said, in actual training, I found myself using only a small portion of the available positions.

Training Use Cases

Where these shine is machine-style training inside a rack. Locked presses, rows, belt squat variations, and controlled hinge patterns all feel natural once you dial in the height and angle.

The inside horizontal locking positions are especially useful. Bringing the arms inward changes grip angles in meaningful ways, giving you closer pressing and rowing positions without swapping handles. In contrast, the extreme outer horizontal positions didn’t add much value for how I train.

The free-swinging mode sounds great on paper for converging and diverging movements, and it does feel smooth. In practice, though, it’s harder to repeat consistently. I see it being more appealing for dynamic or experimental training styles than structured strength work.

Tradeoffs & Limitations

The biggest limitation is attachment compatibility. While the mounting system works on both 5/8" and 1" racks, all usable attachment points are 5/8". If your gym is built around 1" accessories, that’s a real bottleneck. I couldn’t use many of my existing handles, connectors, or brackets because of this.

Price is another factor. You’re paying for a lot of engineering and features, some of which you may rarely use. Personally, I’d like to see a simplified version without the swivel mechanism at a lower cost, because the adjustable brackets and rollers do most of the heavy lifting.

Lastly, some smaller details—like the basic D10 pins—feel underwhelming relative to the overall price, especially when upgraded pins are sold separately.

Value & Alternatives

From a build quality and functionality standpoint, the price makes sense. You’re getting a complete, refined system without having to source individual components.

That said, if you’re comfortable with DIY solutions, a Vendetta-style bracket setup paired with basic lever arms can get you most of the way there for less money. The Halo Arms are about convenience, refinement, and integration—not minimum cost.

Who Should Buy This

Home gym owners who want machine-style versatility without adding standalone machines.
Lifters who value precise setup, repeatability, and build quality.
Anyone already planning to use lever arms for multiple movement patterns.

Who Should Skip It

Anyone who just wants basic lever arm functionality.
Owners of 1"-only accessory ecosystems who rely heavily on aftermarket attachments.
Lifters who won’t use the adjustable stops or locking features consistently.

Final Verdict

The PRx Build Limitless Halo Arms are extremely well-designed lever arms with real advantages over simpler systems. They’re not necessary for everyone, but for the right home gym, they deliver a level of control and refinement that’s hard to match.
