Product Details

High-performance new and remanufactured machines — inspected, serviced, and delivered with warranty.

The BUILT Strength Fractal Series Leg Extension isolates the quadriceps through a seated extension with an ergonomic seat angle engineered to reduce knee pressure — the seat geometry positions the hip and thigh in the correct relationship to the knee joint, distributing the extension forces more evenly across the patellar tendon and reducing shear stress under heavy loading. An adjustable backrest and pivoting ankle pad accommodate different leg lengths for precise positioning before every set.

A 280 lb selectorized stack supports bilateral and unilateral leg extensions with smooth, consistent tension through the full extension arc. A 636 lb heavy-duty commercial steel frame delivers the structural stability and longevity for sustained professional quad isolation training. New.

Ergonomic Seat Angle — Reduced Knee Pressure
The seat angle positions the hip and thigh correctly relative to the knee joint — distributing extension forces more evenly and reducing patellar tendon shear stress under heavy loading for joint-friendly quad isolation training.
Adjustable Backrest & Pivoting Ankle Pad
An adjustable backrest and pivoting ankle pad accommodate any leg length and preferred starting position — keeping the knee joint correctly aligned with the pivot axis for consistent quad loading across all user sizes.
Bilateral & Unilateral Extension
Both legs together for standard bilateral quad development, or single-leg unilateral work for addressing left-right strength imbalances — both options supported by the same 280 lb selectorized stack without any attachment change.
280 lb Stack · 636 lb Commercial Frame
A 280 lb selectorized stack covers light quad activation through serious progressive loading. The 636 lb commercial-grade steel frame provides the structural stability for sustained high-frequency professional quad isolation training.
