Absolutely love this attachment, I've got the older version for the super bench. Like any other ironmaster attachment this saves so much room in my gym, and can get a killer leg pump. Not only can I do bicep curls in my rack, now I can do leg curls in my rack.

This is the only leg developer attachment I have owned, so bear that in mind for my review. It's fine. It gets the job done. The resistance curve is obviously all over the place, but that's a feature of all leg developers like this (I do want to try some cable attachment hacks at some point). It's super stable on the bench, although it feels janky that you have to raise the bench, insert the attachment and then drop it to the ground -- between two weight bench settings. That said, it's solid. I get a fair amount of use out of this, and it's well built.

I bought this on sale to tide me over until Dialed Motion's hits. That said - it works well. I added a pulley to the main support to route a FT cable through and used a barbell 'belt squat' collar to hold the cable on the weight horn. It's a simple setup that can be upgraded like many owners have, but even on it's own - its pretty good. I had and sold the FA leg developer because it was a nuisance to move/store/setup. This is so simple and especially on my FT - just as good.

As is, this piece is marginally decent. I upgraded the rollers to wider diameter injection molded ones. I also added a longer weight horn and use a 4” weight plate spacer to push the plates further out to get a better resistance curve. I also swapped out the side bolts for some eyebolts and connect my functional trainer to it. With those mods the performance bumps up. I can’t wait for Dialed Motion to release their leg curl compatible with IM bench, but for now, this is the best option available, without buying a stand-alone unit.

It works very well with the Super Bench. It’s easy to attach and does exactly what you’d expect. The pads are comfortable and are of good quality. It does require bands to help keep tension. It doesn’t stand up on its own making it awkward to store.
