Lifeline LLJG Jungle Gym

I worked out at a gym that had these and they do work fine, but for extended use they can get a bit uncomfortable. Obviously the handle is not padded, but beyond that they are hard to put your feet into (with shoes, as a guy especially) for elevated pushups, and the metal length adjusters can scratch you up pretty good when you’re doing pushups the other way (generally still gets in the way even if your sleeves are long).

TRX are more expensive because they’re a lot better in all these facets, but if your budget is really tiny and you don’t mind going cheap for the short haul until you can get nicer equipment, they’ll work.
