The Grid – Jammer Arm Kit (Pair)

The HyperFX R7523C Jammer Arm Kit is a heavy-duty, multi-functional training attachment designed to transform the HyperFX GRID system into a dynamic strength and power station.

Engineered to replicate plate-loaded machine movements within a modular rig environment, the Jammer Arms deliver explosive pressing, pulling and athletic training versatility — without adding standalone equipment.

This is not a fixed machine.

It is adaptable strength built into your infrastructure.

Designed for Dynamic Performance Training

The R7523C Jammer Arm Kit allows athletes to perform:

• Plate-loaded chest presses
• Shoulder presses
• Incline and decline pressing variations
• Rows and pulling movements
• Explosive push training
• Athletic drive and power work

Mounted to the Grid uprights, the independent arms allow natural movement patterns and adjustable positioning to suit different exercises and athlete heights.

Push. Pull. Drive. Explode.

Independent Arm Functionality

Supplied as a pair, the Jammer Arms operate independently, enabling:

• Bilateral or unilateral training
• Strength imbalance correction
• Variable pressing angles
• Progressive overload programming

They create machine-style movement capability within the open architecture of the GRID system.

Commercial-Grade Construction

Manufactured from heavy-duty steel and built for high-load environments, the R7523C delivers:

• 46.2kg reinforced structural weight (pair)
• Stable mounting within Griduprights
• High load-bearing capacity
• Durable black powder-coated finish

Engineered to withstand explosive movement and repeated high-intensity use.

Modular Integration

Fully compatible with the HyperFX Grid Series rigs and racks, the R7523C:

• Mounts securely using standard GRID hardware
• Integrates into single or multi-cell configurations
• Expands functional training capability without increasing footprint
• Maintains structural and visual consistency across the system

It turns your rig into a performance machine.
