OVERVIEW

Bring commercial-quality leg workouts into your home gym with the 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 lock-pin mechanism — 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 & Adjustability

Comfort & 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 lock-pin mechanism. It’s a quick, one-person setup with no heavy lifting required.

    This leg extension leg curl is better than any I have used in commercial gyms. I am delighted to have it as part of my home gym. The ability to have 3 different methods of resistance is amazing. Love this piece of equipment.

    High quality and high cost. It's a game changer for my home gym.

    Nothing beats a good leg extension and curl for pump and finisher after squats. This one works as well as you could want. Build quality is great. Price to get a bench and the attachment is pretty high but the build quality to justify it is definitely there.

    Fantastic Attachment

    In my honest opinion the people that are complaining about this thing are gym Karens. This thing does exactly what it’s supposed to and it does it well. Is it as easy as going to a gym and sitting down on a $5000 machine…no. But for an at home attachment at this price point I find it impressive. Very well built and despite what some people are saying it literally takes 30 seconds to set up. I have included a video to prove it and I wasn’t even in a hurry. If you want to add an attachment like this to your home setup don’t hesitate with this purchase. The cable attachment works exactly as it should.

    Great

    Well made. Feels very stable. Easy to attach to bench and cable system. Not too heavy to move or slide into position when paired with bench.

    Allows for full range of motion for extensions and curls. (I’m 5’10”). Using cable attachment you will have resistance through out movement. Using free weights, at the top of the arch you will lose a little.

    Very pleased

    Just what the Dr ordered

    Well built and just what I need. My leg curls are weak but that’s about to change and the leg extension gets five stars as well :)
