Build Your Legs
You can do a lot with a barbell and dumbbells, but isolating the quads and hammies is challenging. This versatile attachment isolates your quads and hammies for some extra sizzle on leg day.

Machine-Like Feeling
This rack attachment lacks the bulk of the machine, without sacrificing the security and stability of leg extension machines at the local gym. Just pop on some plates and let 'er rip.
Product Details
Economically isolate your quads & hammies to build a nice set of wheels.
The Leg Extension/Curl Rack Attachment offers a machine-like feel and stability without taking up valuable real estate in your home gym. This beefy attachment has a weight plate capacity of 250lbs and a user capacity of 250lbs.
The Leg Extension/Curl unlocks seated leg extensions, so you can blast your quads but don't forget your hammies! They can be isolated one at a time with standing single-leg hamstring curls for some juicy hams worthy of Sunday dinner. Throw on some resistance bands for tension you can cut with a knife (which we do not recommend).
Choose the Leg Extension/Curl Power Rack Attachment that coordinates with your power rack uprights and hole size.
IMPORTANT: Your power rack MUST be bolted down when using the Leg Extension/Curl to ensure user and equipment safety. For maximal stability, use this attachment on the inside of your rack.

- AHArthur H.Verified BuyerRated 4 out of 5 starsYesterdayleg curl/ extension attachment
4 star review. the machine almost fits my 3x3 rack from xtreme monkey. the machine does a fantastic job for leg day just add a band to it to create more tension on the down ward portion. it is a solid build and can carry alot of weight. I wish it fit snuggly in my rack I had to add wedges to keep it from swaying.

Overall design is great, am using on a Rep 5000 rack with no fitment issues.
Like the concept of the eyelet for cable attachment but disliked how it moved the pad around on the bottom pad pivot point almost would have like the pad to be solid at the end of extension arm. No issues when only plate loaded.
Due to the weight and awkward center of gravity it would be nice if there was handle mounted for easier instal and removal.
Other than the things above it fills a void I had missing in my home gym at a good price point and i would repurchase if I had to.

We are so happy to hear you have been overall pleased with your purchase and that this has filled the void you were missing before.

A great unit, feels rock solid, is silky smooth, and jacks up the quads. I love this thing.
Bells of Steel CanadaHi Matt. Thank you so much for reviewing our leg curl/leg extension. We are so pleased to hear you have enjoyed your new piece and found it to be of high quality at an affordable price. We hope you continue to love using it for many years to come. Sincerely, Marcus & the BoS team - MLMike L.Verified BuyerRated 5 out of 5 stars1 year agoThe perfect addition to my home gym!
Initially I was a little skeptical with the leg extension purchase. For two reasons. The first being, the rack I have is a different manufacturer and no 5/8s holes but still 3” columns. The second reason, some times ancillary products like this never work as advertised and do not have the same manufactured quality one expects…
As to my first hesitation. I’m extremely happy to report that this leg extension fits perfectly on my rig. I was able to drill a 5/8” hole myself and mount with ease.
Secondly, the overall quality of this unit blew away my expectations. It’s very heavy duty! Works exactly as advertised! Very smooth range of motion! It’s exactly what I needed to take my leg workouts to the next level.
If you’ve been looking for a leg extension machine for you home. Look no further!! This piece of equipment is exactly what you need!
Bells of Steel CanadaHi Mike, Thank you so much for the awesome review of our leg extension/leg curl. We are so happy you have been pleased with this piece, and that it has checked all the necessary boxes. We hope to see you again soon !

I’m enjoying my Manticore Leg Attachment for my rack. It does fit slightly loose but the quality is good for the price and convenience of saving space when not in use. I also use a light resistance band off a band peg and the weight horn to help with ROM at the start point. I’m very pleased with this adjustment.
