Primal Performance Series 125kg Pin-Select - Leg Extension
The Primal Performance Series Leg Extension is a seated pin loaded quad machine where users straighten the knee against a 125 kg weight stack. It fits in 980 × 1240 mm, stands 1620 mm tall and weighs 284 kg, a sensible size for any leg line.
It is the most direct way to load the quads without the hips or back getting involved, and dual hinge foot and knee adjusters let every user set the pad and pivot correctly in seconds.
Who it is for
- Commercial gyms that need a core leg machine every member will use
- PT studios building quad strength in clients who are not squatting yet
- Sports and S&C facilities targeting knee extensor strength
- Rehab and return to sport programs that need controllable, isolated quad loading
Key features
- Dual hinge foot and knee adjusters to line the pivot up with the knee and place the shin pad correctly
- 125 kg pin select stack for fine control from light rehab loads to heavy sets
- Gas sprung adjustments for fast changeovers
- 3 mm laser cut steel frame with an electro powder coated matte black finish
- Urethane injection moulded pads with double stitched, customisable covers
- 1000 kg rated cables and a laser cut frame shroud
What it trains and how to program it
Knee extension in a seated position isolates the quadriceps, including the rectus femoris, which squats load less directly.
- Primary: quadriceps (vastus lateralis, vastus medialis, vastus intermedius, rectus femoris)
- Secondary: minimal; the hip flexors stabilise the seated position
- Pre exhaust sets before squats or leg press
- Rehab loading after knee injury, starting with light pin settings
- Pausing at the top for quad contraction and knee control

Frequently asked questions
What footprint does the Leg Extension have?
The machine is 980 × 1240 mm and 1620 mm tall. Keep roughly 600 mm free around it so users can sit in and swing their legs clear, giving a zone of about 2.2 × 2.4 m.
What stack does it use?
A 125 kg pin select stack. Users change the weight by moving the pin.
Is ceiling height an issue?
No. It is 1620 mm tall and the movement happens at knee height, so a standard 2.4 m ceiling is more than enough.
What warranty comes with it?
Primal Strength states a full commercial use warranty of 5 years on the frame, 3 years on parts, and 1 year on pads, cables, pulleys and wearables, plus 1 year labour.
Can you deliver and install it?
Yes. We ship Australia-wide from our Melbourne warehouse, and most metro deliveries arrive 1 to 7 business days after dispatch. Packed, this machine weighs 322 kg, so some regional addresses need a freight quote. It ships in a 1700 × 760 × 690 mm crate. Use the Ask about this machine form on this page and we will quote delivery and installation for your site.
Is a leg extension safe for the knees?
Used with a sensible load and correct pad setup, yes. The dual hinge adjusters let you align the machine's pivot with the knee joint, which is the main thing that keeps the movement comfortable. Start light and build up.
Balance it with the Primal Prone Leg Curl or Seated Hamstring Curl so quads and hamstrings get equal attention.
