Product details
Quad training aligned to the knee's axis
A leg extension that sits the user out of line stresses the knee and loses the quad. The Spirit SP-4305 Leg Extension adjusts the back pad for proper alignment with the machine's axis of rotation, so members train the quadriceps through a clean, guided range.
Who it's for
Commercial gyms, hotel fitness centres, clubs, college gyms and rehab-oriented facilities that want a guided quad station.
Key benefits
The back pad adjusts for proper alignment with the machine's axis of rotation. The lower tibia pad self-adjusts, limiting the number of necessary set-up changes. The range of motion is adjustable for users with limited knee flexion, which suits rehab work. A 115 kg stack, integrated rep counter and top-cap storage complete the station.
