These are fine, they get the job done and are usually included with equipment for free. I never really thought about collars until I owned a home gym, but once you use something nice, it's hard to go back to these.

I had this and didn't like the how passive the knurling was. It got the job done but wasn't anything special for sure. I upgraded to the Rep version because it was part of a bundle and I would say the knurling and build quality is better, but not by a ton.

I bought these on FBMP form a guy who had them sitting in a barn and they were covered in rust. Bout them for less than .50 per lb and refinished them and sold them. The weights were inaccurate and there was a lot of slop when I had them on the bar. I do like that they are easy to grip and I love the nostalgia factor form using them in an old Gold's gym in Harrisburg, NC when I had just gotten out of college.

I got this mod for the Rep fitness selectorized low row from a seller on Etsy called AndersonWeldingLLC, you can also search "RBS Low Row/ Curl Pulley Mod" and you'll find it. Prior to installing this, the cable was too low. I know it doesn't seem like a lot but this raised the pulley about six inches off the ground and makes it much more comfortable when using the low row. It doesn't work with the ares, just an FYI.

These are great, and I would recommend them to anyone at any level of their lifting or fitness journey. They are great for prehab or rehab, warming up, or building strength in your hips and core, and eliminating lower back pain. These, along with the corssover symmetry bands and my reverse hype and GHD have been instrumental in building a bullet proof posterior chain :)

I had a gnarly case of golfers elbow (same as tennis elbow but on the inside of the elbow) years ago and had to go to physical therapy to get dry needling done. I was going once a week for a few months getting that done, and they recommended I get one of these to do between sessions. Within a couple weeks the pain disappeared. I’ve been using it a few times a week as warmup/prehab and haven’t had any issues since.

These are sweet. Easily snap attachments in and out quickly. They’re small enough and light so that anyone can easily use them. A must have for anyone who switches out cable attachments!

When I was in my true meathead phase in my mid twenties and didn't care about anything other than getting huge these were the plates that my gym had. I loved loading up any machine with these and going to town. Obviously not great for deadlift, but they are easy to grip and well built. I love the look and feel of them.
