Rings on ceiling

Hi, I'm thinking of attaching my rings to ceiling and I was wondering if this will do?

Can someone tell me if this is acceptable?

Thx,

Depending on your ceiling (it's structure and what it's made of) and how much you weigh, it might not be strong enough.

If you have a friend that knows about that sort of thing (maybe a builder, architect or engineer) you could ask them if they could take a look.
