Product Details

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

The BUILT Strength OG Series Plate Loaded Leg Extension / Seated Leg Curl switches between quad isolation and hamstring development via a quick-change pop-pin selector — no tools, no significant setup time between exercises. The transition is designed to be fast and intuitive, keeping training momentum high without a lengthy reconfiguration between movements.

A self-adjusting lower leg pad automatically maintains correct alignment through both exercises, and the adjustable back pad and start position settings accommodate any user size. A firm round thigh pad locks the body stable during curls to prevent hip lift and keep hamstring load consistent throughout the movement. Starting at 20 lb with plate-loaded resistance — warm-up through maximal loading with no stack ceiling. Two integrated weight horns keep plates organized on the unit. New.

Pop-Pin Quick-Change Between Exercises
A pop-pin selector converts the machine between leg extension and seated leg curl without tools — a fast, intuitive transition that keeps training intensity high without significant setup time between movements.
Self-Adjusting Lower Leg Pad
The lower leg pad automatically adjusts to maintain correct alignment through both extension and curl movements — reducing manual setup between exercises and ensuring proper positioning for every user without additional adjustment steps.
Firm Round Thigh Pad
A firm round thigh pad braces the leg during seated curls — preventing hip lift and keeping the hamstrings under consistent, direct load through the full curl arc without compensation from the hip flexors.
Adjustable Back Pad & Start Positions
Back pad and start position both adjust independently for any user size — setting the correct hip angle and range of motion for both exercises before the first rep begins and maintaining it throughout the set.
Plate-Loaded — 20 lb Starting Weight
Olympic plate loading with a 20 lb starting weight covers warm-up and technique work through to maximal loading — no stack ceiling, unrestricted progressive overload for serious quad and hamstring development over time.
