Quad and Hamstring Isolation Without the Machine
Leg extensions and leg curls are the two movements home gyms almost always give up on, because the machines that do them are enormous. This PRx attachment puts both on your rack. It tabs and pins onto your existing setup and works with the PRx Axis Pad to give you a proper seated extension and a supported curl.
At 37 lb and 16" x 23.5" x 24", it goes on and comes off without help and stores in a corner rather than owning a wall. The Axis Pad is required, and you can run it with or without a functional trainer or pulley system.
Key Features
Seated leg extension and lying or seated leg curl from a single piece of hardware.
Locates on tabs and locks with pins, so setup and teardown take a minute rather than an afternoon.
Use the 12" weight post with plates, or run it off a compatible PRx functional trainer or pulley system.
5" diameter by 9" long rollers spread pressure across the shin and ankle instead of digging in.
Works with Profile PRO, Profile CORE, Profile ONE, Profile Folding Full Cage and Build Limitless racks.
A hard finish that stands up to plate loading and repeated handling.
37 lb and 16" x 23.5" x 24" means it tucks away when you are done with lower-body day.
Racks without 4" side hole spacing can still run it using PRx's modified installation process.
Description
Squats and deadlifts build the legs, but they do not isolate them. Quad extension and hamstring curl work is where you address the weak link, rehab a cranky knee, or add volume without frying your lower back. Buying two commercial machines to do it is not realistic in a garage. This attachment is.
It builds on the PRx Axis Pad, which is required for every compatible rack. The attachment locates on tabs and locks with pins, turning the pad into a seat with a roller arm in front of your shins. Flip your position and the same rollers support a curl. Loading comes from the 12" weight post if you are running plates, or from a pulley if you have a functional trainer already on the rack.
The roller pads are 5" in diameter and 9" long, which is the size that actually matters when you are pushing hard extensions. Narrow rollers concentrate pressure on the front of the ankle and turn a good set into an endurance test for your shins. These spread it out.
Compatibility is broad but specific, so check the list below before ordering. Note that Profile ONE 2x3 racks are front mount only, Build Limitless 6-post, full cage and wall mount configurations require floor mounting, and the attachment is not compatible with the PRx Fold-In ONE.
