I don't have them, but if you have any interest in climbing and grip strength you might like these ring-like object with climbing board additions. Here a review by training pal.

I have a set of resistance bands like this one (some random off name brand)

It's pretty cheap and it's the piece of equipment I use the most after my rings. I use them for shoulder dislocates, band pull aparts, face pulls, band resisted sumo deadlifts, band resisted pushups, band assisted planche work, etc. I paid something like 35€ for 4 different bands IIRC

Paralletes are nice to have if you want to increase the range of motion pike pushups (you can also just use stairs though)

Prices are being gouged right now, unfortunately. I got this set a week or so ago and I really like them, but now they're $5 higher. Usually these go for $30ish.

There's also this set for $5 more, but it comes with an extra band and a higher resistance overall. I prob would have gotten these had they been in stock at the time.

Otherwise you can get them directly from China on AliExpress for $25-$30 or so, but it'll take a few weeks to get them
