Hi all,

I'm interesting in working out more outside, so I'd like to install some kind of jungle gym in my backyard. I'm looking for something simple, like something you find in a park or on the streets of China (those who have been there probably know what I'm referring to). My only requirement is that it be long-lasting, and enable me to work on pullups. Ideally it would just consist of two metal bars coming out of the ground with a bar connecting them at the top.

I'm wondering if you guys had any idea where I could buy such a thing. I'm pretty sure it exists, but I have no idea where to start looking.
