Description
The Authentique Leg Extension machine is a seated quadriceps-isolation station from our Authentique professional strength range. A padded roller arm guides knee extension through an adjustable range, making it the reference machine for building the front of the thigh — and one of the most versatile tools a gym floor owns for knee-strength work.

- Seated knee-extension movement isolating all four quadriceps heads
- Adjustable positions matching the machine to each member’s limb length
- Premium steel frame and upholstery for intensive commercial service
- Commercial-grade specification in line with EN ISO 20957-1 Class S (professional use)

From bodybuilding staple to knee-health tool
The leg extension has two audiences. Physique-focused members use it to train the quadriceps with a precision squats cannot match — constant tension, full knee flexion to lockout, and easy drop sets. Meanwhile, controlled open-chain knee extension is a standard element in strength maintenance for older members and structured return-to-training work, because load starts light and progresses in small increments. Few stations serve both groups so directly.

Frequently asked questions
Which muscles does the leg extension target?
The quadriceps — rectus femoris and the three vastus muscles — in near-complete isolation, which is what makes the station so effective for focused development.
Should it be paired with a leg curl machine?
Yes. Balanced quadriceps and hamstring strength protects the knee; most floors install the two stations side by side.
What adjustments does it offer?
Back pad and roller-arm positions adjust to individual limb proportions so every member works through a correct axis of rotation.
