Why Use The Ironmaster Leg Attachment?

Ironmaster, an industry leader in home strength training equipment, is constantly striving to produce the best, hard-wearing equipment, guaranteed to last you a lifetime. You should only have to purchase home gym equipment once. So why settle for anything less than the best?

Flexible weight plate options

Along with post-2011 Quick-Lock Dumbbell weight plates, you can use Standard or Olympic weight plates to the load rating of 200lbs / 90kgs. Slow down your reps, and perfect your form, and you shouldn’t need more than that for seated leg extensions and lying leg curls.

Note: Pre-2011 Quick-Lock Dumbbell weight plates may not fit due to the close tolerances on the centre holes of the plates.

Extra smooth bearing action

Once you’ve felt Ironmaster’s super smooth bearing action you won’t settle for anything else.  Experience fluid, continuous movement as you put your muscles under tension.

Adjustable roller pad positions

Leg training is never going to be the most comfortable experience, but we don’t think your choice of kit should contribute to that. Setting yourself up correctly helps you get the most out of each set (and minimises risk of injuries). Our adjustable two-position roller pads allow you to seat yourself correctly, and the pad density is just the right balance of comfort and durability.

Exercises using the Leg Attachment!

IronmasterUK Quadriceps

Leg Extension

Target the quadriceps with this isolation exercise. Adjust the roller pad height so that, when you are seated upright on the Super Bench, the lower roller pad sits just above your foot on your shin. Your legs be at a 90 degree angle in the resting position, before extending your legs to the maximum while squeezing your quads. You can also do single legged leg extensions.

IronmasterUK Hamstring Group

Leg Curl

To target the hamstrings, adjust the roller pad distance so that (when lying face down, with your legs straight), your knees lay just past the first set of roller pads and the second set are just a few inches below your calves. Curl your legs to 90 degrees, focusing on your hamstrings and keeping your torso stationary. You can also do this movement with one leg at a time (unilateral leg curls).

“A solid and well-designed attachment. Comfortable pads for ankle and knee support. The angles for quad and hamstrings exercises feel natural and it does not force you into an uncomfortable position.” – Richard T.

Buy it once, buy it right

Our design, durability and build quality means you will never have to purchase a leg attachment again. This is not just another cheap leg attachment for a home bench. This is exactly what you need to grow your legs in your home gym.

“What an awesome home bench leg attachment. Most home gym bench leg attachments are flimsy, noisy, low load capacity and designed so poorly they hurt your knees. The Ironmaster leg attachment seems bomb-proof.” – Omar

We’re not just offering you a Leg Attachment. We’re giving you the opportunity to push yourself to the limit knowing your equipment can withstand anything you can throw at it. We know you’re not slowing down anytime soon. We’ll be here for you during every rep of every set, with the kit you need for the perfect training set up.

Remember, you can’t spell legendary without LEG DAY!

Please note: Due to the flat height of the Super Bench, users 6ft 2” and above may have floor clearance issues. This is easily remedied by rotating the bench up a notch so it’s in a slight decline position and when using heavy weight you will just need to put a 3” block of timber under the support foot.

  1. Love this. Well, well made. Even has a bronze bushing for smoothness. Heavy and solid.

    Padding is thick and dense. Very comfortable too.

    I consider it an essential accessory, and use both Olympic and quick lock dumbbell plates with it.

    Like all Ironmaster master gear I’ve picked up so far…rock solid, and cost effective.

  2. FANTASTIC quality! Just like everything else I’ve purchased from Iron Master, this too is of the absolute highest quality.
    My only nit pick with it is that when plates are loaded and you’re doing leg extensions large plates can touch your shins (45 lb plate, in my case). For me, it’s simply annoying as it’s a very light touch, but for someone with large lower legs, they could find it more than just irritating. My solution would be to add a lower-weight plates on first (ie 10#) as a buffer to create some distance

  3. Solid and well-designed attachment. Comfortable pads for ankle and knee support. The angles for quad and hamstrings exercises feel natural and does not force you into an uncomfortable position. I like the option of using either standard and Olympic (adapter included) weights. Some assembly tools included, but you need two wrenches as well.

  4. I bought this attachment for my superbench and love it. This attachment easily attaches to your Ironmaster Super Bench and is great for adding leg workouts to your bench. Has 200+ lbs capacity and includes an Olympic Sleeve for Olympic or Standard weight, Heavy duty foam padding and heavy duty bearing action This attachment like all Iron master products is solid, well built and will last forever.

  5. I am really impressed with this attachment. I didn’t have high hopes for it, since most leg attachments I had tried years ago… All sucked. But this one rocks!

  6. It adapts very well to the bench and makes leg work out complete.

  7. This is a good addition to the Ironmaster super-bench that will hopefully include a few adjustments in the future. The assembly is easy, taking only a few minutes or so. The motion of both the extension and leg curl is smooth. A nice feature is that there are different placements for the pads for the taller or shorter person. Unfortunately, for the taller person, your feet may touch the floor on the extensions–mine do, so I have to remove my shoes to even use this add-on. Pros: *sturdy feel *Olympic weight option *easy to attach and detach *smooth extension Cons: *not enough clearance. I’m 6’1 and if I’m wearing shoes I can’t use the extension as my feet hit the ground on each pass. *another clearance issue is adding 45lb Olympic weights. You at least need a few spacer weights so that larger plates don’t bump against the frame.

  9. This attachment works perfectly for my purposes. The only drawback is the 200 pound weight limit. I have done leg extensions with more weight than that however. But since I didn’t want to damage it, I just started doing single leg extensions. That’s probably better anyway. The adjustments could have more options, but overall I’m happy with it and it fits me well. I’m 6′ tall. I’d recommend it to anyone who has the super bench.

  12. After purchasing the SuperBench I started looking to see if I would benefit from any of the attachments Ironmaster provided. As I hadnt trained my legs in far too long due to lack of equipment at home i figured the leg developer would be a good place to start. I was not disappointed! Solid, good range of motion and sturdy enough to take 90kg! Perfect! I am so happy as I am finally able to train my full body at home. I would highly recommend this addition to anyone thinking of buying it.

  13. I find the attachment perfect and I’m 6’2″. Very well built thick steel used throughout. You can tell where the hundred quid has gone! Little things that stand out also like the allen bolt foam pad retainers! a big step up from the crud you get on budget kit. Customer service from Valley Fitness was perfect.

  14. What an awesome home bench leg attachment. Most home gym bench leg attachments are flimsy, noisy, low load capacity and designed so poorly they hurt your knees. The Ironmaster leg attachment seems bomb-proof. It takes a higher load than any home bench leg attachment on the market that I’ve seen. It feels really smooth and puts the resistance at the rights places and supports your knees perfectly.

  15. the leg attachment could be better, if the pivot was higher more in line with Knee joint. The bench tips when 100kg leg raise is reached (I put weight on oposite side to keep it stable). The pads are not enough when doing leg curls. The rubber foot falls off easy. but it adequate

  16. Have had this attachment for a few years now and it has stood the test of time. The unit is very stable when attached to the Superbench as the bar on the bottom gives it great stability. I only use the leg extension for higher rep warm ups and the leg curl at the end of a workout for higher reps, so although only moderate weights are used it is more than adequate for my workouts.

  17. This accessory is one of the main reasons I bought my Superbench back in 2007. Not only does it work great for leg extensions and hamstring curl, but I use a towel and wrap it around the pads to work my back and biceps. I also remove the top bar and pads to use the leg curls in a single leg standing position with the bench in a slight decline to keep pad above my knee. It actually feels better than the ones at 24 hour fitness in Los Angeles. Especially with the leg extensions where the commercial machine feel like they are lop sided and stress one leg over the other. I have use mine for 13 years and even competed for bodybuilding using this setup.

  18. Received this last week and used it for the first time this week with a client who found it very uncomfortable for leg curls. I got back in touch with iron master and James replied quickly advising to position the body so the pad is as low down the thigh as possible. Tried this with the next client and no complaints, tried it myself and can confirm it is comfortable to use. Build quality wise it is the usual excellent built to last a lifetime “buy once” quality.

  19. Works well for tall guys too
    Just bought this accessory after years of using the Super Bench. It works as expected. I’m 6’ 6” so I knew I would need to raise the attachment to accommodate my long legs. I simply use a 2 by 4 under the footing below the attachment to raise the bench. Works like a charm and still very stable. The attachment requires some assembly but it was easy to do and took about 15 minutes. The attachment itself is very sturdy and attaches in a few seconds. I expect many years of use. I recommend this attachment for all levels of users.
