Pin Loaded Leg Extension - Legacy Series

Legacy Series Leg Extension - Commercial Pin Loaded Machine

Quad Isolation | Enclosed 100kg Stack | 3mm Steel Frame | 10-Year Frame Warranty

Squats and presses build the legs - the leg extension finishes the quads. The Legacy Series Leg Extension isolates all four heads of the quadriceps through a strict knee-extension arc, with precision ergonomics that line the knee up with the pivot so the tension lands on the muscle, not the joint.

The adjustable back pad and ankle rollers tailor the fit to users of all sizes in seconds, and the low-resistance pin adjustment on the 100kg enclosed stack means the station turns over fast on busy floors - from rehab-light to legs-shaking heavy with one pin.

Built on a 3mm commercial steel frame at 268.5kg with a maintenance-free pulley system, it's made for intensive daily use on premium floors.

FAQs

What muscles does the leg extension work?
The quadriceps, isolated - all four heads extend the knee, and this is the one machine that trains them with nothing else helping.

Is it bad for the knees?
Used properly, the opposite: the adjustable pads line the knee up with the machine's pivot, and the controlled arc strengthens the muscles that support the joint. It's a staple of knee rehab programs for exactly that reason.

Is it beginner-friendly?
Very - sit down, set the rollers, pick a pin. It's one of the first machines every new member learns.

What pairs well with it?
Its natural partner is the Legacy Seated Leg Curl - quads and hamstrings from two stations - or see the Legacy Dual Leg Extension / Curl for both in one footprint.

Can I upgrade the weight stack?
Yes - on made-to-order builds the 100kg stack can be increased to 140kg at $10 per kilogram. Get in touch to spec it.

Can I customise the frame and upholstery?
Yes - made-to-order builds are available in 16 frame colours and 12 upholstery colours on an 8-12 week lead time. See the full colour chart below.

Do you offer delivery and installation?
Yes - Australia-wide delivery, with professional installation through our own technician team in Sydney. At 268.5kg this is one to let our team place and level. Contact us to discuss freight access and site requirements.
