The Freak Athlete Leg Developer is a PERFECT product! As advertised, attaching it is super straightforward and easy. The angle of the weight horn ensures that tension is felt through the entire lift, greatly increasing hypertrophy. This product is a one-of-a-kind, must-have for any home gym enthusiast wanting to work their quads, hamstrings, and the rest of the posterior chain. Great work Benji and crew!!
Thanks so much, Jeremy! Pumped to hear the Leg Developer is hitting the mark and helping you crush your quad, hamstring, and posterior chain work! 💪 The tension feedback is such a game-changer for hypertrophy, and it’s awesome to know it’s making a difference in your training. DMed you about this but I would decline the Hyper when doing hamstring curls! Appreciate the shoutout to Benji and the team—we’ll keep bringing the heat!🔥 Keep up the amazing work!

Freak Athlete Leg Developer & Belt Squat Attachment: A Customer’s Take I’ve been using the Freak Athlete Leg Developer and Belt Squat Attachment with my Hyper Pro for months, and they’re fantastic for my small home gym. The Leg Developer adds leg extensions and hamstring curls, feeling smooth and solid with adjustable rollers that fit my 6’ frame perfectly. The Belt Squat lets me hit quads and glutes without stressing my back, and the included belt and calf block are nice touches. Both handle heavy weights—up to 500 lbs—without wobbling, built like tanks with sturdy steel. They barely take up space, folding away with the Hyper Pro into a corner. The movements feel natural, great for my “knees over toes” routine, and I love how they keep my workouts safe and effective. Got both attachments on a promo so I can’t beat the value. Customer service is awesome - they email right back! Totally worth it for versatile, durable gear.

I loooove the leg developer! Easy to remove and very effective! 💪 the guys from FA really thought this through..cudos

This attachment is a dream come true. Solidly built, smooth movements, and the pads are better than I have used at a commercial gym. Additionally all that this attachment can do besides lower body makes this a must have.

Amazing piece of equipment. I have realized the gym is only necessary for my needs 1-2 days a week. The rest I can get done in my home gym. The Freak Athlete Hyper Leg Developer is not only a great addition it enables me to rehab my mom also. The upperbody kit enables me to extend its use from just back & leg days to arms also.

Easy assembly. Move smoothly while using it. The burn in the quads are real. Maybe it could have 5 more centimeters on the lower range to go for a full stretch of the quads, but it feels good already

I just received the Pro Upgrade Kit and the Leg kit, both fantastic. The Pro Kit addresses any question marks that the OG unit may have had, the new material is great and it feels way better without the Velcro attachmentments. The Leg unit is solid!! This thing is dialled in, it feels like a pro-gym unit! Awesome job with this one

As many have attested, the leg developer as a leg extension and curl is very good for a plate loaded machine. The strength curve is genuinely very good and it feels very stable. The ability to lie down flat during leg extensions also provides a unique stimulus on the quads. Additionally, as I haven't seen this posted elsewhere, I have found that I can use the leg developer for seated calf raises, using the former back base as a foot pad, an identical piece of steel tubing as a kickstand, and a flat bench. This is also a very good use of the attachment.

It was a longer wait than I expected, but it was definitely worth it! I love the equipment. It is well made and has a smooth ROM that allows for tension throughout the movement. A quality product.
Out of all of the leg developer attachments I have ever tried - and there have been many - this is easily the most sturdy, heavy duty, and simultaneously smooth one of all time. Assembly video and how-to video are both excellent. Keep up the great work, FA!
I absolutely love this equipment. I use it almost every day for one reason or another. As an industrial designer, I can really appreciate that build quality and engineering. Everything has been thought of. I absolutely love it and in my opinion, it's an absolute must have for any home gym.
I just love it. I had a standalone machine from atletica which i sold a week after i got this attachement. Great rom, excellent strength curve and sturdy quality. Also great work of your engineers.
Very surprised at how effective this attachment is. I'd tried other plate loaded leg extension / curl attachments for my weight bench and yeah, there was definitely spots where the resistance was lacking. As stated in the description of this attachment, the weight is there from the second you move your feet. I was just using a 20kg plate and could really feel it for both extensions and curls. And as there's no back support, you can lean back and really open that hip up for the leg extensions. The only thing I wish they could have added (functionality wise) is the ability to do standing leg curls. And yes, I have also since ordered the cable machine attachment which was released recently for this. I reckon it's going to make an already awesome bit of kit. Honestly, I'm still amazed at the useful functionality these guys have managed to pack into this piece of kit. A little exy but totally justifiable. Zero regrets.
Honestly, the FreakAthlete FAR EXCEEDED my expectations. Its a truly incredible piece of equipment that has been getting regular use in our fitness facility.
Love the Freak Athlete bench and the leg attachment is amazing. It’s perfect for my home gym. The attachment is really quick to put on and take off and the whole bench stands upright and sits neatly against the wall.
Strong and smooth; consistent tension through the whole movement. Quick to put up and down. I do indeed love it. Can be adapted for seated calf raise (single leg). I was surprised not to see this covered online on various channels that look to get the maximum amount of exercises out of it. Set up as per leg extension but sit on a chair facing in the opposite direction. Block under one foot and lift bottom pad to rest on knee. THEN load on your plates. You need to do one calf at a time to generate sufficient force. Just switch between legs and take the plates off before you attempt to move away or you can get into a pickle. Works like a dream! A little awkward to be off-centre so I’ll get an extra pad to centralise the weight somehow.
Instructions were next level. IKEA could take note. Build quality is decent, good enough for a home gym. I had one issue with a bolt stripping but it did not affect the machine's use. The engineering on this thing is amazing. Every exercise that I have used it for it has worked perfectly. When upright, it takes up very little space in the corner of my home gym.
Hi team! Congratulations! Everything -all equipment- works just excellent!! I am very happy with all the equipment: hyper pro, leg developer and GHD. I appreciate all your efforts to build an awesome machine/s for all my body, more specifically for my knees, hips, low back and core…
Awesome comfort and consistent smooth tension. Best instructions I have seen on any product. Great value.
The Nordic Hyper and Leg Developer Pro are the best pieces of gym equipment that I have purchased. They take the home gym experience to the next level. Would definitely recommend to all gym enthusiasts.
After a slightly longer than anticipated wait (but for the better as the design was improved, so happy to wait) it arrived. Assembly was straight forward, thanks to the video instructions and perfectly labeled bags (I wish others would put step number details on each part). Only had it a few days so I've just done a couple test sets but damn, it works really well. Leg extensions with just a 20kg plate lit up my quads like nobody's business and there was resistance from start to finish. Honestly didn't feel any part of the move that didn't have resistance. Lying leg curls - just as good. It also looked like I might have been able to do standing leg curls but alas, the lengths just didn't line up - but only just :( But absolutely nothing negative about that as it was never mentioned I could do them, I just wanted to try. So, overall, this has taken the Freak Athlete Nordic bench to the next level. Is it expensive - maybe. Is it worth it - definitely.
Love the attachment, it was a task receiving it though, my original order took ages to come then had to wait months for the leg developer.
an extremely useful add on. great to workout with and just the addition I needed. Full leg workouts now possible!
Really happy with the leg developer, adds a lot to an already great machine. Only had it a couple of days but looking forward to training with it a lot more. Was easy to put together and use. Personally for me I would prefer a paper copy instruction manual, especially for the Nordic Hyper itself. So it is easier to see the best settings for each different exercise and pointers for ideal form etc
Really love the leg attachment, the angle for both the leg extension and leg curl is perfect, as well as the height adjustments for each. Set up is as easy as would be expected for such an attachment, I don't think you could have made it any simpler so well done. The only way the attachment could be made perfect is with an upgrade to the arm attachment for leg exts. The idea of them to create tension for the lift is great, but I have used it with my clients and I need to give a safety warning every time (that if you put weight on them at all getting into the machine they are dangerous and fall out). Just needs some sort of locking mechanism (twisting method or otherwise) and the machine is 10/10 perfect. Can only give a 9.5/10 until then but I'm sure you'll come up with a solution as you have continued to do. Keep up the good work, Neil.
Amazing attachment to the nordic ghd equipment. Easy to attach and use. I'm having fun doing home workout! Definitely a great buy!
I thank the owners, for the freak athlete equipment. One of a kinda. As all I've been awaiting a extra month for the leg exstension attachment. All other equipment out there, is too narrow or not long enough in the leg, or not able to take the stress of the weight on the front of the leg, which causes stability problems and unusable. Freak athlete leg exstension is very stable!! Anyway i'm very happy, very smooth and full range, no cheating, just full range of movement. Its important you can use Olympic weights with comfort. Leg curl is one of my favourite exercises. (Leg day every day..) Freak athlete equipment Decline leg curl, is better than old skool flat leg curl, as you again get to full bicep of your hamstring. Many thanks to the owners, designer, for constructing this peace of equipment. They are great people and helpful if you get a chance to speak with them. YOGI. THANK YOU. Triple AAA RATING..
This is what the world needs. An ingenious way to train. I love the new attachment and the amount of excercises I can do.
I have the leg developer one week now , it works great , no complaints , the whole machine is incredible !!!!
Fits perfectly and have used it a few times. You would think it was a permanent part but attaches/detaches very easily. Love it!
This is by far the most versatile and best piece of fitness equipment I've ever owned. Even my kids enjoy all the variety of exercises we can do. I would highly recommend this to anyone interested in improving their fitness. A real game changer!
You guys actually pulled it off. Not just the promised shipping period, but also the quality and ergonomy of it. And again the packaging. GG
It amazing. The tension is there for the offset to the completion of the rep. It’s so easy to install, Feels and looks structurally sound. It’s everything I hoped it would be and much more. Love it. Thank you
Absolutely fantastic piece of kit in addition to the hyper pro. It's a must have for your garage / home gym!
Love to sit down and Play with it Thank You guys You did an amazing work of Art Philipp Corpoartis.com
“This tool is relevant in rehabilitation as it enables precise, progressive, and functional work to prepare the body.”
Another excellent piece of equipment from Freak Athlete. Resistance throughout the range of motion, smooth action, very easy to install and remove, takes up little space, very well built, great quality. Exactly as advertised.
Build quality is superb, especially the pads. Movement feels really good, especially the leg extension. It also provides constant tension on the muscle. The hyper pro is probably the best home gym equipment you can purchase right now, you won't regret it.
Received my Leg Developer, as usual the QR code and the video are really helpful to assemble the product. Tried some leg extension work, you can load heavy weight using two legs, but tried heavy unilateral work and it seems harmful for the machine (it puts to much tension on one side). Same thing while doing leg curl. Really good product overall
I recently purchased the Leg Developer Attachment, and I am very pleased with it. The build quality is solid, and it feels durable during use. It's easy to attach and adjust, making it suitable for a variety of exercises. The padding is comfortable and provides good support, which is essential for leg workouts. I’ve noticed significant improvements in the effectiveness of my leg training sessions since I started using it. Overall, this has been a great purchase for me. I highly recommend it to anyone looking to enhance their lower body workouts with a reliable and well-made attachment.
During covid-19 I started investing in my home-gym. Both the Hyper itself and later the leg developer have made my garage better equipped than an average gym and I love it. It is easy to setup and takes up almost no space. I can only give it my warmest recommendations.
Such a smart way to upgrade an already excellent gym tool. Really sturdy and very usable, well done!
Great add on! Took a while to assemble but it works well and I love how the tension remains the same throughout both of the movements.
It was worth the wait. It took 6 mos to get into my hands. They modified it a few times before it got to me so it was nice to get the latest and greatest. As usual, super sturdy even with some heavy weight. This is the icing on the cake. We'll done {tips hat}
Great piece of equipment! I herniated two discs in late 2023 and was looking for a piece of equipment to help build my body back up. This has been great to build my posterior chain and I'm very glad I finally made the purchase.
Fantastic product/ great addition to home gym. Generally I’ve been really impressed with freak athletes customer service and quality of goods!
Fantastic piece of kit! The leg developer feels really well built and a quality bit of equipment. The leg movements feel great with the developer, particularly leg raises - they really burn! Well done Freak Athlete on making the Hyper even more brilliant!
Loving the leg developer. It's easy to attach, the directions of how to put it together were clear, and it's comfortable to use. The Freak Athlete team has thought of everything. Wonderful job, Freak Athlete. Thank you for making an amazing product that is efficient and affordable.
Leg attachment was everything I was hoping for. It’s easy to assemble and attach. I love how smooth it feels for both extensions and curls.
Super happy with the Nordic hyper and the leg developer . Great to be able to do so many exercises with a machine that takes up minimal room ! The unit was shipped on the time they said they would and the customer service was excellent aswell regarding the questions I had about delivery.
I'm 56 years old. I was having pain in my knees and plantar faciitis. And MY leg developer help me in only 2 weeks, I'm feeling less pain. Thank you!
Love the add on! The handles however are pretty much useless. They don’t really lock in properly and can actually be dangerous if your relying on them for support as they can give out and fall out. Other than that, it’s amazing. The ease at which it connects and comes apart is fantastic. Really love the addition to my private studio.
This was well worth the wait and a must have addition to your Hyper pro!!! Directions for assembly were well thought out and easy to follow. I appreciate the addition of the written directions, which made assembly go by much faster. The video was very well designed this go around and easy to follow. Used the hamstring curl setup this morning. Easy to set the equipment up and you get the added benefit of feeling the weight at the top AND bottom of the exercise. This is a great piece of equipment to have if you're tight on space.
I am very pleased with how the leg extension / leg curl works. It is easy to install, feels solid and offers a lot of range of motion. I am an athletic therapist, and I will definitely use it with my patients.
best piece of home gym equipment I have. For the price in consideration of what you get, well worth the money
Nicer than I expected. I am still getting familiar with it. It looks very well made and will last a very long time.
This is another well made product from Freak Athlete. It was easy to assemble and easy to attach to the Hyper GHD. The motion is very smooth. Highly recommended.
Great addition to an already an amazing piece of equipment. Space saving gym equipment that easily goes on and off is always a plus in my book.
Works really well, great tension throughout. The pad is high quality so doesn’t dig into your legs when using. Very happy so far
Looks good feels good and is easy to set up and store for when it’s needed Definitely worth it for any home gym
I ordered the leg developer just after receiving my original Freak bench. Although delivery was delayed due to the redesign of the leg developer after user feedback, I was happy to wait for the superior product. I’m very happy with the range of adjustment (I am tall and have had problems with leg extensions in the past) and the overall excellent quality of the leg developer. My Freak Athlete bench was already my favourite home gym equipment and now it is even more so!
⭐⭐⭐⭐⭐ The leg attachment by Freak Athlete is a game-changer for anyone serious about leg training. It’s sturdy, easy to attach, and provides excellent support and stability during workouts. The design is intuitive, so setup is straightforward, even for those who aren't particularly handy with equipment. I’ve noticed a significant improvement in the targeting of leg muscles during squats and lunges since I started using it. The comfort padding is a huge plus, too—no more awkward or painful leg placements! Overall, this attachment has quickly become an essential part of my routine. Highly recommended for anyone looking to enhance their leg day.
Your assembly video made it so easy to put together. The exercise videos, coupled with the upper body attachment, gave me great ideas for creating a full-body workout that mixed body weight with weights. I ❤️ my Freak Athlete.
I love this attachment but it keeps getting stuck in the main equipment when it’s fitted in (gets stuck at the welded ends) and then I have a lot of difficulty removing it after use
Hi Sharon! We're so sorry to hear you're having issues with your order! Kindly check the email we sent you for further assistance. We look forward to hearing back!
It was not shipped till I was contacted by Freak Athlete to see if I had received it. I said I had not, they said one would be shipped soon. That was a little weird to myself.
Hi Scott! We're so sorry for any confusion here! We appreciate your response to our initial email, and we were happy to ensure you would receive your order as soon as possible. If there's anything else we can help with, feel free to reach out!
The leg developer attachment is great. The instructions are not the same level of quality. They do not demonstrate the same level of care and thoughtfulness: - a QR code should not be the only option to find instructions. A QR code means I have to start on my phone, whereas I want to start on my laptop - there should be manuals not just videos. It is tedious to have to repeatedly watch videos or search through videos just to check how to do one thing - all videos should be on YouTube. Currently you have a mix of YouTube and another platform - all videos should be easily discoverable on your YouTube channel. I cannot find your YouTube instruction videos if I go to your YouTube channel - important features are hidden away in the middle of videos: e.g. the fact that I can unscrew the bar to switch olympic plates to 1 inch plates. For me this was massive. I was on the verge of buying a whole new set of weight plates before I discovered this.
Hi David! Thank you so much for a detailed feedback. We'll take note of this and pass it along to our team. We hope you're still able to enjoy the equipment, and if there's anything we can help you with, feel free to reach out!

My only issue is when you connect the Leg Developer Attachment to the Hyper Pro, the height difference between the upper roller of the attachment (the one under the thigh) and the pads of the hyper pro makes it uncomfortable to do the leg extension exercise due to the pressure placed on the hamstring. I would have to place a folded mat on the hyper pro to remove the height difference and make it more comfortable to do the exercise.
It's okay. Nice addition to the base model. As attachments come into the fray the company as a whole innovates what's appealing. Little pricey though
Unfortunately the pad for GHDs isn’t sufficient. I did ask for a replacement and was told it would be another £200. Very disappointing as you promote this excercise and it does not deliver. Threw the the pad away as it doesn’t work and was taking up space in the gym.
Overall a good product with decent quality feel. Bit bulky to store and would have gotten 5stars if it could be stored together with the rest of the machine
Questo e' l'inizio di un percorso che potrà apportare in un primo momento sollievo alle loro carenze fisiche ma poi, nel proseguimento del trattamento un maggiore rafforzamento muscolare tale da superare le rigidità ed acquistare elasticità muscolare che dà il benessere fisico alle persone che hanno bisogno di un ausilio tecnico come "Freak Athletico EU "
Leg attachment super good plus to original hyper Pro waiting to get those ghd paddings cause that i have wait for
Pretty cool piece of kit. Works great with two legs. However when using it as a single leg extension of is a bit to wonky.
The delivery was postponed several times, and I received it three months later than initially planned. I was promised an upgraded version as compensation, but I didn't even receive the TRX attachment or an anchor for the leg developer.
So far I have no clue what is for what it doesn’t work I don’t understand atcs’l how to use it it is just sitting there and I can’t work out with it
Generally speaking, Hyper Pro and this leg developer are a genius invention, I love them so much! However, over time, I've identified some flaws as I use them more and more. The supporting board for the Nordic Core move seems to have some leveling issues due to the way it’s fixed to the main body, and the leg developer I've got is not centered when attached coz the push tightener is only on one side. I've also been noticing the main body may be wobbly although all pins are screwed up properly. Hope you guys keep upgrading it to make it even more perfect!
Overall I love the new capabilities it brings. I'm just not a fan of how loose the attachment feels despite the locking hinge being in place
Works good for what it is. Great addition to the base product. Can be somewhat unsteady. Vinyl upgrade is nice! Great space saver for home gym
Main reason for buying the Nordic Hyper was for space saving purposes as it folds up nicely. The leg developer complete eliminates all the space gains. There is no way to store or transport it effectively, which eliminates the benefits of the hyper. Very disappointed.
