Hanging from Aluminium Pergola

[newguy5000]

Hi guys. I will probably be moving house soon and will have to get rid of most of my gym equipment because it will no longer fit. I'll probably put it in storage. The new place i will most likely be moving to does have an aluminum pergola over a wooden decking. I was wondering if anyone has hung rings from pergolas made from aluminum and wondered if they held up or if it was a poor idea? Here is what kind of pergola i am talking about:

If not i'll have to hang them at a gym.
