OVERVIEW

Bring commercial-quality leg workouts into your home gym with the best Leg Extension and Leg Curl Bench Attachment. This compact, space-saving accessory instantly transforms your REP® BlackWing™, Nighthawk™, or AB-5000 bench into a versatile leg isolation station — no need for bulky, standalone equipment. Effortlessly switch between leg extensions and prone hamstring curls for a complete lower-body session.

Easily attach it to your weight bench using the convenient 2 lock-pin mechanisms — a quick, one-person setup with no heavy lifting.

FEATURES

Multi-Functional Design

Multi-Functional Design

Train quads and hamstrings with one space-saving attachment. Move seamlessly from leg extensions to prone leg curls without swapping gear — ideal for supersets and efficient sessions.
3 Resistance Options

3 Resistance Options

Choose your resistance — plates, bands, cables, or any combination — to train your way. Dual-sided, plate-loaded weight horns and integrated band pegs make loading fast and seamless, while the optional bolt-on cable kit lets you connect directly to any cable machine.
Comfort and Adjustability

Comfort and Adjustability

Lock in for leg extensions with the side handles, while adjustable shin pads let you customize this attachment to fit your body. The flat thigh pad spreads the load evenly across your legs — unlike a traditional roller — making leg curls more comfortable.
Strength Curve

Strength Curve

Each form of resistance has an optimized strength curve often missing from other brands' attachments. Pairing resistance bands with weight plates ensures consistent tension throughout your range of motion, and the built-in cam lever ensures smooth, consistent tension when attached to a cable machine. A refined, optimized strength curve challenges your quads and hamstrings through their strongest and weakest points for more effective results.​
Engineered for Strength

Engineered for Strength

A wide, solid base plants this unit to the floor so it won’t shift, sway, or tip — even when you’re moving the full 250 lbs it’s rated for. The overbuilt frame and reinforced stance deliver superior stability and a locked-in feel rep after rep. No flex, no wobble, no flimsy shortcuts — just dependable strength you can trust under max load.
Roll to Position, Pin to Train

Roll to Position, Pin to Train

Built-in wheels do more than make storage easy — they let you slide, tweak, and dial in your setup in seconds, especially handy when using the optional cable attachment. Installation is just as simple: attach the receiver brackets and secure the unit to your bench with the 2 lock-pin mechanisms. It’s a quick, one-person setup with no heavy lifting required.

    Awesome

    I am roughly 280 pounds and 6'1. I put this out there to express how awesome this thing is. It is solid, with no wiggle when using it or getting on or off it. I did purchase the wider pad for the bench, which I am super glad I did, as I am not a skinny guy. But this attachment was super easy to put together and is extremely solid. The main thing I want to point out is that the online pictures make it look bigger than it is, which was a concern for my fellow home-gym friends and me. But it is actually very well-sized and replaced my leg curl and leg extension machine, opening up a lot of space for me in my home gym. The picture I have attached helps show that it doesn't take up a ton of space.

    Exactly What I Was Looking For

    Very pleased with this purchase. Before buying it, I used a leg extension/curl rack attachment from another company, and this has been a substantial upgrade in just about every way.

    One feature I’ve really appreciated is the versatility. It can be used with weight plates, resistance bands, and REP’s cable attachment.

    The leg extension feels great, and unlike my previous setup, the leg curl is actually something I enjoy using and regularly include in my workouts. It’s also much easier to handle and set up than the rack attachment I used previously.

    Overall, it’s been a great addition to my home gym.

    Excellent

    This is a really excellent attachment! Great force curve, comfy rollers, plus the ability to add bands for top resistance. It also comes on and off the bench very quickly.
