Look up Peace Earth gymnastic rings on Amazon. The straps are slightly wider than normal with the number marks. As for the rings they are slightly wider as well helping grip strength. I think they work great.

I'd recommend getting a set of gymnastic rings. You can throw them over any horizontal beam, pole, or tree branch. You can use them for both pulling, pushing, and isometrics. These are the ones I use https://www.amazon.com/PACEARTH-Gymnastics-Adjustable-Exercise-Non-Slip/dp/B07CGCD7JH/ref=sr_1_5?crid=3QVE1G3XRQ0MM&dchild=1&keywords=gymnastics+rings&qid=1601659367&sprefix=gymnas%2Caps%2C161&sr=8-5
