Pin Loaded Prone Leg Curl / Extension Pin Machine [HS-X Series]

HS-X Series Prone Leg Curl / Extension - Commercial Pin Loaded Machine

Hamstrings & Quads, One Station | 96kg Weight Stack | 10-Year Frame Warranty

The HS-X Prone Leg Curl / Extension covers both sides of the thigh from a single 96kg stack: a prone leg curl for the hamstrings and a seated leg extension for the quads. Reconfigure in seconds and the same station trains the complete upper leg - no second machine, no second footprint.

The prone position is the point of difference: lying face-down with hips extended puts the hamstrings under stretch before the rep starts, which most lifters feel as a deeper, harder contraction than seated curls give. Flip to the extension position and the quads get the same strict, isolated treatment.

Adjustable settings fit users of all sizes, and the ergonomic pad layout supports correct form through both movements. Built on 11-gauge carbon steel at 225kg with polyurethane pads and premium PU leather, it's made for commercial leg-day volume.

FAQs

How does one machine train hamstrings and quads?
The station reconfigures between two positions: lie prone and curl for the hamstrings, or sit and extend for the quads. Same stack, opposite side of the thigh - a complete upper-leg session on one machine.

Prone leg curl vs seated leg curl - what's the difference?
The lying position with hips extended puts the hamstrings under stretch at the start of every rep, which many lifters feel as a deeper contraction. Serious leg programs use both; the prone curl is the classic.

Is it beginner-friendly?
Yes - both movements run on fixed, guided paths that are easy to learn, and the adjustable settings fit every user size. The pin stack scales from rehab-light to heavy.

Can I upgrade the weight stack?
Yes - on made-to-order builds the 96kg + 4.6kg stack can be increased to 117kg + 4.6kg or 138kg + 4.6kg at $10 per extra 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.
