In reply to Mountain Spirit:
I have a couple of their steel mace's, great fun/training tool.
Start with a 5kg or lighter if you are considering one though.
Parralettes could be a good option too.
In regards to the rings, I have 2 sets of gymnastic rings, one I have had are about 13 years old now and are some sort of fibre glass, the other are cheap wooden ones. Both serve the purpose that they were intended for.
