Thank you sir today I maked two items very useful

[@takioc]

Great ideas and very well made. Thanks. I saw a video saying that to prevent knee injury when doing leg extensions the seat should cover the hamstring and be close to the back of the knee. Could you advise how to accommodate this when using your bench or when building yours from scratch? Thanks

[@MattLees-Nunan]

Hmmm... I would cut the seat to 300mm wide × 400mm long to make sure it comes out further. I would also ensure that the edge is covered up with matting so that it feels comfortable on your hamstrings

[@takioc]

@@MattLees-Nunan Thanks for your reply Matt. Is the size you just mentioned the same size you suggest in the video?

[@notgaryoldman1178]

Looks excellent!

[@MattLees-Nunan]

Thanks! It's been a handy machine in the IsoGym😍

[@minecraftlord568]

That’s the best diy hamstring setup on KZbin respect man. Can you load it up with enough weight to give your hamstrings a solid blast??

[@MattLees-Nunan]

Thank you🙏 Yeah definitely. I get 55kg on there but to add more weight; all you need to do is make the tubing longer so you can add extra weight.

[@fightermma]

@@MattLees-Nunan Does it matter if the castor wheel says max capacity is 40kg? That doesn't matter does it since the wood and bench is holding most of the weight right?

[@MattLees-Nunan]

Great video, but I’m missing what are the lengths of the 2 pieces 70mm x 45mm pine cut for the leg frame, then attached together with the 200mm x 70mm flat bracket? 2:19 minutes Thanks, Ted

[@MattLees-Nunan]

Hi Ted, thank you very much! There should be a full list of materials in the description of the video. Let me know if you have any other questions👍

[@ancushing1]

I know what you mean. I'm making this project and I'm not mm savy. You;d think he could answer such a simple question. Not everyone is knowledgeable about Euro measurements.

Nice idea but you can’t put much weight the hinge from the wheel holder would probably break.

Any chance we can get a video of you using this bench to do standing leg curls? I want to see how efficient it would be using the front leg extension part but to do standing leg curls. I am deciding to either create just a lying leg curl part or just a standing leg curl part.

[@huulocle6246]

👍👍👏👏Tks....Good luck....

[@fightermma]

Hey bro can you make a video of you using the bench for a dummbell Chest press and incline press while the leg attachment is still on and then show you detaching the leg curl and then doing the flat and incline press? Would be good to see the difference and how easy it is or isn't using it without detaching.

[@MattLees-Nunan]

Hey, sorry about the late reply! I can't now unfortunately as it is in a friend's gym

It really depends on the individual. DM me on insta😊

[@fightermma]

Can you use copper tubing instead of the galvanised steel tube you used or would that be too weak?

[@MattLees-Nunan]

Copper is a great idea. Just very expensive😯

[@fightermma]

@@MattLees-Nunan I'm just struggling to find pipes. We have different terms here in the UK for different tools and materials.

[@MattLees-Nunan]

Yeah, I can imagine it's harder over there. Well, I suppose if it's thick enough then it's fine👌

[@fightermma]

@@MattLees-Nunan I just don't want the copper to bend. Maybe a conduit pipe would be better.

[@HarderstyleSociety]

@@fightermma look for "Threaded Pipe zinc Coated" or "Galvanised Malleable Iron threaded Pipe" on Ebay or Amazon that's what i used.

[@EsotericAshh]

Such a bad ass !!

[@MattLees-Nunan]

You know it😎

[@fightermma]

How do you detach the leg curl from the bench? Can you detach it without tools?

[@MattLees-Nunan]

Yep! Easily done without tools. The eyelit bolt just needs to be hand-tight👌

Can you provide the measurements for the height it needs to be please?

[@mineget2608]

how much load can this thing take? lets say i wanna add 91kg on it, can it take that? and it would be proportional to the one in the gyms?

[@MattLees-Nunan]

Hi! Hmmm....I've never had that much on there, so I wouldn't be able to say yes or no. It might be a matter of trialling a little bit at a time to see how it goes. You may find that amount of weight could cause the front to lean forward... in this case, maybe attaching the back to the floor or putting something heavy over the top of the back leg would be helpful.

What the max weight you can leg curl or do for leg extensions?

With this one, I can put 50kg on there but you can always extend the bar out further to load more weight on!
