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 & 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 2 lock-pin mechanisms. It’s a quick, one-person setup with no heavy lifting required.

    Overall, Really Amazing

    Pros:

    - Build quality is fantastic

    - Works great with the Ares 2.0

    - Initial build is really easy and setting it up with the bench is quick and simple.

    - Let extensions and curls feel great. Just be warned that it will humble you quickly, especially when attached to cables

    Cons/Opportunities:

    - As other reviews have mentioned, the starting position can be a little uncomfortable depending on your height, especially for leg curls. Felt like I was hyper-extending my knees. I glued some magnets to a few different thicknesses of wood (3/4" to 1.5") so I can change out and find the position that feels better for my wife and I. Seems like an opportunity for Rep to provide some spacer blocks with the unit, or a way to adjust the stopper to accommodate different people. Not a big deal overall, but it could be a low cost way for Rep to provide a lot of value for customers.

    - There is also a lot of mentioning of the size of the unit in reviews. Yes, it's not small, but it's really not that bad for what it is. One thing that I think could help is if there was a way to collapse the handles when not in use. That would help a lot, as I tend to run into those when walking by it. Recommendation for a future version.

    Overall:

    I have enjoyed using this over the past month or two. It's is easy to nitpick on all the details compared to other leg extension machines and attachments, but the bottom line is that it works exceptionally well for what it is intended to do. In the time I've used…

    Leg attachment

    Very well engineered. Resistance curve is amazing. The ability to use bands with weights is a game changer. The leg curl is a bit too heavy for novice trainers. The only other critique is that the leg roller pad is too restrictive for use as a decline bench.

    Couldn't be happier with this plate form, Sad I had a power rack before I knew about Rep fitness.

    Received Today 1/12/26 Took about an hour to Put together by myself, everything was straight forward and easy peezy. I've used it for lying Hamstring curl and I couldn't be more happy with how smooth it feels, Currently in between Squats sets writing this review and I can't wait for some leg extensions next!

    well hello to all and happy new year. this is not my only rep peice of equipment. i have several bars that i use exclusively. an open trap bar a cambered bar and a colorado bar. sorry rep i use a bells of steel rack. the manticore!but what i have is awesome to use. i am no new comer to lifting,i had an awakening after having a gastric sleeve surgery done at 67 years old. i spent a good chunk of money on everything to not go to a gym. i have what i need in my garage. thank you for a good product. one last thing ,please dont take this the wrong way but there is something called quality control you should look into.
