Yes. It's semi-slang, so translators aren't going to be useful. https://ru.wiktionary.org/wiki/%D1%82%D1%83%D1%80%D0%BD%D0%B8%D0%BA#%D0%A0%D1%83%D1%81%D1%81%D0%BA%D0%B8%D0%B9

"tourniquet" would be "турникет". More formal terms that would get translated better would be "перекладина", and "перекладина для подтягивания" would be literally "stienis priekš pievilkšanās".

"Pull-up bar" was the term I couldn't recall in the moment. Although historically these (like the ones we have in Soviet courtyards) are technically just gymnastic horizontal bars, not specifically for pull-ups. In the forest here, there's a bunch of them in random locations - literally a metal bar between 2 trees.
