iso arms
FEATURES
Starting Point Matters (And So Does Sleeve Position)
Each arm features a dual hex port sleeve you can slide along the lever to change your starting point:
• Closer to the hinge = heavier (more torque)
• Closer to the end = lighter (less torque)
This lets you fine-tune resistance not just with weight plates, but with mechanical advantage. It’s like physics class—but with gains.
BUT… A Quick Word on Leverage
The original Isolator’s weight arm was 1:1 matched to the lever arm, giving it a smooth, even resistance curve.
The Iso Arms’ built-in weight arms? Much shorter.
Which means:
• If you skip the Adjustable Weight Arm, it may be tough to load enough weight for big-boy movements
• If you try to cheat it by sliding the sleeve way down low, yeah… you can do the movement, but your biomechanics may file a formal complaint
GRAB THE ACCESSORIES
Want Real Power? Grab the Accessories.
Adjustable Weight Arm + Dual Weight Horn
• Extends the length of the weight arm = more load potential
• Dual weight horns = stack more plates = happy lifter noises
• Perfect for dips, rows, presses, pulldowns, and anything where you want that commercial machine feel
Already Bought the Adjustable Multi Horn?
Boom. You’ve already got our upgraded rotational shaft. You’re good to go.
Didn’t Get It Yet?
If you’re grabbing the adjustable weight arm + dual horns now, you’ll want the rotational shaft upgrade too—especially for offset loading or heavier movement setups.
Sticking With the Original Weight Arm?
Totally fine for lighter movements or isolation work. Just know your limits.
PERFECT FOR
Movement Menu (aka: Your New Workout Obsession)

• Front high rows
• Lat pulldowns

How Do Iso Arms Compare to Our Other Arm Systems?
We will offer three tiers of modular arm systems soon, so you can pick the one that matches your goals and budget:
1. ISO ARMS (THIS PAGE)
• Mount to the Isolator (single upright)
• Quick to attach and remove
• Medium versatility
• Best for those expanding their existing Isolator setup with leverage-style training
• Most budget-friendly option
2. Mini Isolator Arms (coming soon)
• Mount to both uprights (rack-based setup)
• Can be removed or left on the rack (user’s choice)
• Higher versatility than Iso Arms
• Axis adjustability depends on the version purchased—some allow converge/diverge mechanics
• Ideal for users wanting more than Iso Arms, but without jumping to the premium Versa level
• Mid-range price point
3. Versa Arms (Coming Soon)
• Mount permanently to full rack (dual uprights with counterweight needed)
• Elite versatility—support both leverage and linear loaded machine movements
• Fully adjustable for start height, grip position, and converging/diverging paths on multiple planes.
• Designed to replicate commercial leverage, linear loaded, and Smith-style machines
• Premium pricing, premium performance
adjustable weight arm
FEATURES
Key Features:
• Fits Exactly Like the Original – Same outer diameter. Slides into the Isolator unit just like the stock arm. No fuss.
• Length Adjustability – Slide and lock to increase the effective torque and resistance. It’s like turning up gravity.
• Compatible with Any of Our Weight Horns – Traditional single horn? Great. New dual horn? Even better.
• Rubber Bump Stop Built In – Protect your rack’s crossmember when you’re training like a savage and the weight arm makes contact.
WHY IT EXISTS
The original Isolator weight arm was designed with a 1:1 lever-to-load ratio—perfect for isolation movements like leg extensions and curls for most lifters.
But not all lifter and now that we’ve unleashed the Iso Arms for full compound movement madness, you’re gonna need more firepower for sure!
Enter: the Adjustable Weight Arm.
WHY YOU'LL PROBABLY NEED IT
Why You’ll Probably Need It
Let’s keep it real:
• Many compound movements with the Iso Arms require more weight than the short stock arm can deliver.
• Certain movements—especially presses, dips, rows—may feel biomechanically off if you don’t have the weight distance dialed in.
• You’ll likely need more load and better leverage. This solves both.
That’s why we strongly recommend:
• At minimum: get the Adjustable Weight Arm
• For optimal performance: get the Adjustable Weight Arm + Dual Weight Horn
Because while you can slide your iso sleeves down to the hinge to increase resistance, some movements just don’t feel right starting way down there. And we want your setup to feel like a machine—not a workaround.

Bundle Smart, Lift Smarter
Already picked up our Dual Weight Horn? You’re halfway there. Pair it with the Adjustable Arm for max load potential and beautiful weight distribution.
Did you get the Adjustable Multi Horn? Good news: you already have our upgraded rotational shaft, which is mandatory when using either the dual weight horns or longer weight arm.
WRAP UP
The Arm That Makes the Arms Work
If you’re going all in on the Iso Arms—or building out a leverage-based setup that actually challenges your strength—this is the no-brainer add-on.
More adjustability. More load capacity. More versatility.
Since starting length is the same as your original isolator arm you can leave this on for normal isolator movements and then when slap the ISO arms on you just pull that pin and grab the length needed with no added setup time or fuss!
The Adjustable Weight Arm isn’t just nice to have. For most lifters, it’s essential.

DUAL WEIGHT HORN
FEATURES
Key Features:
• Standard Fit, Upgraded Performance – Slides into the Isolator’s original or Adjustable Weight Arm with zero drama.
• Dual Horn Configuration – Load plates on both sides for better balance, smoother feel, and serious resistance.
• Integrated Rubber Bumper – Built into the sleeve itself, this bumper lets the horn rest safely on your rack’s crossmember during certain setups—without scuffing or damaging your equipment.
RECOMMENDED UPGRADES
Using this horn with Iso Arms and/or the Adjustable Weight Arm?
You’re going to need to bring in the big guns.
The standard rotational shaft on the Isolator wasn’t designed to handle this much load. That’s why we highly recommend upgrading to our Heavy-Duty Rotational Shaft for safe, smooth operation under heavier conditions.
WRAP UP
Stack More. Train Harder. Stay Protected.
If you’re serious about pushing weight—and especially if you’re pairing Iso Arms with our Adjustable Weight Arm—this is not an optional upgrade. It’s the key to getting enough load on the machine safely, smoothly, and without beating up your rack in the process.
