Features & Benefits

Dual Plate-Loaded Movement Arms

The DS-918 includes two ISO movement arms with a dual pivot free-floating system. This allows each side to move independently, helping users train pressing strength, control, and athletic power.

Free-Floating Converging Arm Design

The free-floating converging movement arms help create a more natural pressing path. The outer weight-loading arm moves in a fixed plane of movement, while the inner actuator arm free floats so the user can find a comfortable training path.

Ground-Based Athletic Training

This jammer is designed for ground-based functional athlete training. It supports explosive pressing movements that help train upper-body drive, trunk stability, and full-body power transfer.

Walk-Through Frame Design

The walk-through frame allows users to enter and exit the machine more easily. The frame also includes a sizable front stabilizer foot to help support the unit during demanding training sessions.

Breakdown Frame for Shipping

The side frames break down into two sections for shipping. This helps make delivery and installation more manageable for commercial facilities and performance training spaces.

Large Multi-Angle Rubber-Coated Grip Handles

The large rubber-coated grip handles allow users to train from different hand positions. This gives athletes and lifters more options for pressing, driving, and explosive movement patterns.

Integrated Plate Storage Horns

The DS-918 includes 8 stainless steel plate storage horns, with 4 horns on each side. This helps keep training plates close to the machine and supports a more organized strength area.

Heavy-Duty Pivot System

The primary outer movement arms use 25mm sealed ball bearings in a sealed housing. The inner actuator arms use bronze bushings for pivot movement, helping support smooth and controlled training motion.

Rubber Foot Pads

Rubber foot pads are included on all floor contact points to help protect flooring and improve stability during use.
