Features & Benefits

Focused Leg Extension Training

The DS-923 is built for isolating the quadriceps through controlled leg extension movement. This makes it a practical addition to lower-body strength programs, athletic development, rehabilitation-style strength work, and general commercial gym use.

Plate Loaded Resistance System

The machine uses a 10" stainless steel weight horn with a safety pin for resistance loading. This gives users a simple way to adjust the training load based on strength level and program needs.

Counterbalanced Movement Arm

The movement arm is counterbalanced and pivots to the right of the seat pad, helping support smoother movement and more controlled repetitions throughout the exercise.

Self-Adjusting Single-Foot Roller

The DS-923 utilizes a self-adjusting single-foot roller to help support fit and comfort during leg extension training. This allows the machine to adapt more easily to different users.

Adjustable Back Pad

The adjustable back pad uses a stainless steel slide tube, allowing users to modify the setup for better positioning and support during training.

Rubber-Coated Side Handles

Two rubber-coated grip handles are positioned on the side of the seat pad to provide added stability and control while training.

Heavy-Duty Pivot System

The primary movement arms use 25mm sealed pillow block ball bearings to support smooth, durable performance during repeated use.

Comfortable Pad Design

The primary seat pad is 24" wide x 23" deep and 2.5" thick, with a 3" bull nose foam wrap at the front. The tapered backrest pad is 11" wide at the bottom x 17" tall and 2.5" thick, helping support user comfort during training.

Integrated Plate Storage

Plate storage is built as a bolt-on tree tower with two 8" stainless steel weight horns and one 4" stainless steel weight horn. This helps keep plates organized and close to the machine.

Durable Commercial Construction

The frame is built with 3" x 2" 11-gauge tubing and 4" x 2" tubing with a 3mm wall, along with sheet steel ranging from 1/4" to 3/8" thickness. Frames also break down into sections for shipping.

Floor Protection Features

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