REP-ISO Arms-5000 series

If you’re looking to pack the functionality of an entire commercial gym into a single power rack, the REP® ISO Arms are the answer. These aren't just "lever arms"—they are a fully modular, plate-loaded system designed to replicate the feel of high-end machines without the massive footprint. By mounting these to the outside of your PR-4000 or PR-5000, you transform your rack from a simple cage into a multi-functional powerhouse.

The secret to the ISO Arms' versatility is the bearing-driven pivot point. This allows the arms to travel through a smooth 180-degree arc, making them perfect for dynamic movements. Unlike cheaper alternatives that feel stiff or jerky, these are engineered for fluid, professional-grade performance.

REP-ISO Arms Features

• Unilateral or Bilateral: Use the arms independently to iron out muscle imbalances or together for traditional compound lifts.
• Locked or Loaded: Use them as "lever arms" for pressing and rowing, or lock them into a fixed position to create a rock-solid station for dips and pull-ups.
• Four-Way Hole Pattern: The arms feature holes on all four sides, making them completely modular. You can slide them up or down your uprights with ease or even attach J-cups directly to the arms for bespoke height adjustments.
• Adjustable Knurled Handles: Get a secure grip with premium knurling. The handles can be adjusted to different angles or removed entirely if you want to swap in other attachments.
• Belt Squat Compatible: Each arm features an integrated eyebolt, allowing you to quickly connect a belt squat attachment—a massive win for those looking to save their spine while torching their quads.
• Smart Storage: When the workout is over, you don't need to strip the arms off. Simply lock them in the upright position against your rack to keep your floor space clear.
