My dogs keep chasing the curl bar fairy away and I can’t bring myself to spend money on an ez curl bar unless it can do something else. So, I bought this because I liked that I could use it with the Voltra as well as for normal ez curl bar movements. It turns out it’s also semi-rackable which is super convenient. And when you put collar on it, it’ll stay put in your j cups. The only thing I don’t love about it is the fat diameter. I’ve got big hands and can wrap my fingers around the bar so it works, but I’d prefer if were a regular diameter. If you don’t have big hands or want to use this for high rep hypertrophy work, you’re gonna want to use grips.

This has been a great addition. Use it all the time for curls, tricep extensions and lat pullovers.

Been using this for about a year and it has been one of my favorite bars/ attachments. I use it mostly for curls with weights or cables, tricep extensions and lat pulldowns. I mostly only have cheap attachments that came with my rack so theres not a ton of competition. I think if I had fat grip v bar for tricep extension or a good lat bar this wouldn't get much use due to being pretty heavy for an attachment but if you don’t have a lot of attachments its neat to have that added use. The knurling on it isn't much but at least it’s there.
