REP Leg Extension & Leg Curl Bench Attachment

Last updated on February 2nd, 2026 at 03:52 pm

I am a JUNKY for Leg Developers. If my count is correct, we’ve had more than 8 different ones over the years in our gym. Leg Extensions almost NEVER leave the rotation for me and my wife, and lying leg curls rotate in and out with other variations. The problem has been that none of the big players, the guys making high quality benches, has ever made a high quality Leg Developer. But we got to take a ride with the REP Leg Extension & Leg Curl Bench Attachment at HomeGymCon and I am intrigued.

And now the day has come… The REP Leg Extension & Leg Curl Bench Attachment has arrived, and it is officially added to the Review Pipeline.

Expected Launch Of This Review

REP Leg Extension & Leg Curl Bench Attachment Overview

REP Fitness has long been the kings of home gym benches. Not only are they aesthetically fantastic, but they have been stable, robust, and fairly affordable compared to their competition. They have managed to push the envelope and level up the entire bench offering space for the home gym community.

BUT… their background in CrossFit and the “anti-machine” mindset that came with it, has left behind some of my favorite aspects of an adjustable bench. Namely, the attachments. I’ve said it before, and I’ll say it again, I don’t care about a bench if it doesn’t take attachments. So even with REP offering arguably the best benches for the price, I never owned one until they announced the REP Leg Extension & Leg Curl Bench Attachment was finally finishing production.

This will attach to a handful of REP’s current bench offerings including the Nighthawk. It will connect via the attachment port at the tail end of the back pad near the wheels, the same spot the decline sit-up attachment has historically worked.

REP Leg Extension & Leg Curl Bench Attachment FAQ

REP Leg Extension & Leg Curl Bench Attachment Features

The REP Leg Extension & Leg Curl Bench Attachment has some pretty nifty features compared to your typical Leg Developer. In the above picture we can see quite a few. First up is REP’s go-to padding and vinyl wrapping. It is something that most leg developers skimp out on, but this will blend in nicely with their benches aesthetically and also improve the longevity of the pads. They are also fully adjustable for different sized athletes, which is a BIG piece for my gym. With myself, my daughter, my wife, and a number of friends and teammates entering our gym, we need something that works for everyone.

We have the built in handles, something I REALLY tried to get Freak Athlete to improve on with their Hyper Pro Leg Developer, which they eventually came through on with the ABX. Handles allow you to PULL yourself into the bench, to be more stable, and focus all the effort into the muscles instead of tendons and supporting structures. Not only is this better for hypertrophy, it is better for the long term health of your knees.

The REP Leg Extension & Leg Curl Bench Attachment is, incase you couldn’t tell by the name, dual purpose. It functions for both Leg Extensions and Lying Leg Curls. It has built in wheels, which is a unique feature for storage and mobility. The majority of leg developers require a unique and creative storage solution, REP is baking theirs right in with a floor base.

The weight pegs are chrome, which means no chipping powdercoat. And a very unique piece, they actually have dual weight horns loaded horizontally. Most leg developers have a single front post. It will be interesting to see how this functions and feels in use.

We also have band pegs to be able to adjust the strength curve (more on that in a second) and the big winner… it is cable driven! Cables, along with a properly designed CAM, allow a leg developer to have a more consistent strength curve so you don’t have that awful too light, too heavy, too light fluctuation that happens with many plate loaded options. This is a big reason why the Hyper Pro Leg Developer was a big win for us, and now the ABX currently holding the top spot.

Initial Thoughts

We got to test the REP Leg Extension & Leg Curl Bench Attachment at HomeGymCon and we had a few notes. First, it is fairly large. Not huge or outrageous, but certainly not a compact unit. You are going to need to plan ahead for storage. It is larger than any other leg developer we have. And considering how the goal of a bench attachment is to not have dedicated space for a machine, we need to REALLY find a balance here.

Second, we found that the strength curve matched up well for leg curls, but needed bands for leg extensions. It tends to fall off at the top when plate loaded. That is helpful for finishing a lying leg curl, but lack luster for leg extensions. In our very initial tests at home so far, it looks like this is still the design choice. So I think you are going to NEED some bands for leg extensions, especially plate loaded.

If you happen to have a VOLTRA I then you can customize the curve to your liking.

Because the leg developer is plate loaded, cable driven, and has band options, you can also get creative and mix and match. So you have options to really get creative here, depending on your goal. Not quite a Prime Fitness Smart CAM system, but we are inching closer.

A piece I didn’t notice at HomeGymCon, but noticed immediately at home, is how this connects to the bench. You actually have to have a retrofit kit from REP to put a piece into the attachment port and add onto the backside of the bench.

Good news is that these don’t impact the bench use at all. You can still store vertically, roll around, and use as normal. It also gives the leg developer TWO connection points, meaning that it is rock solid attached to the bench. The downside is that if you change benches (say you move from the Zero Gap to the Nighthawk), you need a new attachment piece. And since you have to put the attachment piece inside the attachment port, if you want to use the Leg Roller, you have to remove that, store it, you name it.

I would have liked to see a more seamless solution here, as it almost feels like two different teams designed their benches and this attachment. But we’ll see if this becomes annoying or frustrating over time.

Other Options On The Market

Buy THIS Leg Developer For Your Home Gym In 2026

We actually love Leg Developers so much, we wrote up an entire article on the topic covering our experiences with a number of options so far. REP is joining a fairly crowded market, but the good news is that they are attacking a higher tier of quality. While a LOT of Leg Developers are simply a post, pivot point, and some pads. The REP Leg Developer has a premium powder coat, adjustment options for different sized athletes, premium rollers and foam, cable options, band options, dual plate horns, wheels for easy transit, and more.

What I’m Looking For In The REP Leg Extension & Leg Curl Bench Attachment

I’ll be comparing the Leg Developer to all the other options we have used in our space. We’ll likely have multiple options in our garage at the same time, to compare side-by-side. I need this to work for bigger athletes like myself at 6ft 240lbs who is leg curling the full stack and doing leg extensions with 6x45s. And I need it to work with my daughter at 8 years old, and everyone in between.

I need this to be easy to set up, use, then put back. I need the storage to not eat up a ton of my space. And I need this to play nicely with my VOLTRAs. Ultimately, I need to know if REP’s $550 price tag is worth it over all of the other options out there.
