Took a long time to find the right plates for my gym. I like their color grading for easy identification and their two handles (instead of 3 or 4). They are pretty thin, so if you need to load a machine with many plates, that comes in handy. The only downside is, that they cost a bit more than most other rubber plates.

The Voltra is the ultimate equipment piece for small spaces. I have a tiny gym and this is why I built it around the Voltra. With all the different mounts the only limit is your imagination. I use it pretty much in every workout to some capacity. Ever since owning a Voltra, using a normal weight stack without eccentric weight just feels weird. I just love working out with it. The biggest downside is the price, especially in Europe it costs way too much ($3000+). Then you have to buy (and often import) mounts to really use it.

I absolutely love my REP PR-5000 rack. The quality is outstanding, and the packing was superb as well. REP has a good ecosystem of attachments that you can add to your rack. And if REP doesn't have it, you can take any other 3x3 1" attachment.

Branded fractional plates that you can get from multiple companies. Payed a bit extra to go with the same brand as my normal weight plates. They fit well without problems on my bars. Due to the rubber, they are "quieter" when putting them on the bar, compared to metal/steel plates.

You can get these really cheap off Amazon. They likely cost half of what other brands charge and are enough to get some plates onto your rack. They can fit 5/8 and 1" holes and there are multiple versions for different rack sizes. My version came with sticker pads that you manually have to attach so that your rack won't get scratched. Once applied, they fit like a glove on my REP PR-5000 (one thick and one normal pad used per weight plate holder).
