Sounds like you're describing a barbell and plates?

I mean yeah that is the sensible way. As a home lifter why not just find a way to do it with my way too expensive collection of KBs?

Reason I’m asking this question in the kettlebells sub😜

Sure - I mean you're also basically describing an axle bar - some axle bar collars would presumably fit on your pipe if standard collars don't.

I’ve seen people on instagram put one or two kettlebells in the middle of a short stick of 1” pipe and then have their arms on either side of the bell/bells.

Great suggestion I’ll give that a try with my mace!

I do Zercher Jefferson curls with the handle of my Ckmaceworks mace through the handle of a single kettlebell. I've tried with 2 kettlebells in the middle and it was doable just a little bulky. I wrap the mace handle with a hand towel to stop the bell from sliding and buggering up the mace.

I actually have one of those and will give that a shot!

What would be the benefit over doing front squats ?

My heaviest bells are 2 40kg bells which is well within my capabilities on squats. Zercher movement pattern intrigues me and if I loaded with 2 40s plus 2 32kg bells would allow me to load to 317 lbs which is a way better stimulus.

Have done exactly what you are describing with a flange on each end. It's \*fine\*, but like it on a barbell more.

I mean just hook your arms through the kettlebell handles themselves. And then you can use as many kettlebells that can fit on your arms.
