Price: $228 (free shipping) Experience with the company: Ordered December 17, 2025 and it was delivered December 23, 2025. Order status was clearly communicated. Experience with the piece: I pair this with the Rep BlackWing adjustable bench. I did not modify it in any way and they work fine together. The leg rollers are slightly higher than the top of the bench, which I remedy by putting an ab mat to create a more level surface. I've used it extensively in the 7+ months that I've had it. I find both the leg extension and curl features to work well. The hamstring rollers can be adjusted depending on which way you orient the attachment to either sit above or below the stem they are on. I prefer the rollers to be on the lower side as I found it to be more comfortable and provide more stretch. The hamstring curl does loose tension at the very peak of the contraction. Final thoughts: I thought I would replace this piece with something "better" down the line, like the Rep x Dialed Motion attachment eventually. However, I went to Home Gym Con 2026 and tried several other leg extension/curls (to include the Rep x Dialed Motion). I was very surprised to find that the only leg extension/curl that I found to feel better enough to consider dropping several hundred dollars on was the Apex bench leg curl/leg extension. I don't know that everyone would have that same experience based on body size/preference for being able to use a cable stack/etc). But for me I find this piece to be more than adequate and I don't plan on replacing it any time soon.

This fits okay on the rep nighthawk. It end up being a little taller than the bench and requires a pad to sit on. Leg extensions feel great for this being a plate loaded attachment. Curls definitely seem like an afterthought like most attachments and are not that great. The pads are comfortable enough and I can get a good stretch using the attachment. It is also very easy to move around and disassemble. I did not personally have to drill an additional hole for this to work.

This leg attachment will work on benches with the same size receiver. I use mine on a REP Blackwing and it fits just fine. The only fit issue was needing to drill additional holes for the REP pin and the post to be at a proper depth. Otherwise the attachment would stick out too far. The bench padding and leg padding do not line up though. So it does feel better using something like the AbMat to help level things off. To be fair though, it looks like even Bolt’s bench and this attachment are offset just the same. As far as the quality of the movements, I think the extension is the better of the 2 while curls are meh. The resistance curve definitely falls off a cliff well before the top of the movements. This would be a great little option if Bolt tweaked the design so you could add bands to help with the curve. It is light and easy enough to move around. I do recommend this depending on budget and one’s expectations.
