The leg extension is a non-negotiable cornerstone for complete lower-body development, and the Allant Seated Leg Extension is engineered to be its ultimate commercial platform. Designed specifically to maximise quadriceps tension without loading the lower back, this selectorized piece features a highly specialised internal cam profile. This cam system alters the resistance throughout the movement, perfectly matching the natural human strength curve so users experience consistent, direct muscle recruitment where they are strongest.
As a Certified Pre-Owned unit, this machine brings world-class durability to your gym floor at an exceptional value. The Gym Experts technical team completely dissects and refurbishes each unit—replacing high-tensile drive belts or cables, cleaning and lubricating the solid steel guide rods, and wrapping the contoured pads in premium, sweat-resistant commercial vinyl. It is a high-traffic, low-maintenance asset that immediately elevates the capability of your free-weight or selectorized strength zones.
Features & Benefits
-
Angled Seat & Back Pad: The ergonomically tilted seat pad forces the user’s hips securely into the backrest, preventing the pelvis from lifting and keeping the work focused entirely on the quads.
-
Range of Motion (ROM) Adjuster: Features an accessible, multi-position start-angle adjuster that lets users limit or extend their range of motion based on flexibility or injury rehabilitation needs.
-
Fast-Pin Weight Stack: High-capacity commercial steel weight stack allows for immediate resistance modifications from the seated position, making it highly effective for intense drop sets.
-
Contoured Stabilization Handles: Side-mounted grab handles feature non-slip rubber grips, allowing lifters to anchor their upper body firmly when tackling maximum weight loads.
-
Full-Length Acrylic Safety Shroud: The sleek, fully enclosed weight stack guard enhances member safety by protecting fingers from moving parts while preserving a clean, premium facility aesthetic.
