So I bought the Fringe Sport Gibbon Arms last month, and I will say I'm extremely happy with them.

But I will say that I'm getting a little FOMO now that the Maxum Mutant Arms (though they're big and ugly) and now Tornado X arms have an option to do 1 to 1 ratio due to the pulley hack. My rack is currently 2 to 1 and adding this functionality would be perfect for me to do lat pull downs off one arm

I am thinking of seeing if there's a way I can maybe utilize that hole in the middle of the arm to add some sort of hook so I can add on a climbing pulley for a 1 to 1 ratio, but would love some ideas here to make an elegant solution.

Maybe use a chain hook into the hole and connect a carabiner to it when I want to do 1 to 1?

I would love some ideas that are easy to implement and wouldn't look terrible.

Made a little fun project out of TPU with my 3-D printer. Usually my projects need multiple iterations to work out, but this worked out perfectly and fit some standard Home Depot eye bolts.

Here is my model to download and print:

I’ve searched everywhere for a D handle that doesn’t have a stitched in place D ring like the photo above. I like these where it’s free floating. Does any one have any idea where I could find them.

While trying to learn fusion 360 CAD, tried to draw a rack attachment for loadable dumbell so that I do not need to get on the floor to chance weight. So I customise the width according to my own custom loadable dumbell and got it laser cut and bended. I can hold the dumbell and put it back easily without squashing my hand.

The holder is made from st37 carbon steel and it's 5mm thick.

For the ones gonna ask about dumbell, it's a custom one made at steel shop. It is 38cm wide and the fixed sleeves have 12cm to load plate. I also have 2.5kg lazer cut plates which are 1cm wide. With 5kg bumper change plate inside, I can easily load 40 kg per dumbell which is enough for me. And the shaft is 29mm with mid to aggressive knurling.

I also have brackets designed and cut. I will be sharing after I get some straps with correct lenght.

If you love DIY gym items, I can’t recommend enough getting a 3D printer! Here’s just a few things I printed specifically for my home gym.

Push the jammer arms with your legs, remove the second set of safety pins and work away.

Trying to find a solution, the jumps in my smith machine are too large. Would like to find a solution to occasionally do half jumps if needed.

Also this affects safety stopper position. For example when I set it at 3 for smith bench press, it’s too high, and 2 is too low to properly protect me.

Does anyone have a DIY fix to this VTS latch. Finally got the VTS set up and realized the either bolt went missed or was shipped without it. I reached out to customer support at bulletproof but looking for a quicker answer is possible

I am assembling a budget block system for a home gym using simple components (rollers, steel cables, spacer anchors). I want to simplify the design as much as possible and save money.

​My plan is to fix the blocks directly to the concrete walls using standard spacer anchors. But I doubt if it's safe enough for a crossover.

​Is it acceptable to attach the blocks directly to the wall with conventional anchors, or will the dynamic load eventually tear them out of the concrete?

​Is it really necessary to install steel profiles (for example, a square pipe) to distribute the load, or is it an overkill for a simple home system?

I will be glad to hear the advice of those who have already fixed such systems directly to the wall. Have you ever come across anchors loosening over time? I would be grateful for advice on choosing the optimal type of anchors for this task.
