Hey man, I have always wanted to see that since I saw Mighty Joe Young, very cool to meet someone else.
Across my searching I have never found any.
When I read the title, I thought OP meant "Metal Music Bands on biceps".
Was going to say look up Marina Lemenovskaya or Candace Kucsulain.
I have seen videos of women breaking plastic loops (or maybe it was a band of tape) on their biceps, I can't remember where it was though.
It used to be a popular thing for MBBs to fasten metal bands around their biceps and snap them open by posing in a big way. It wasn't literally breaking them, but of course it was still a real "feat." You can see it in earlier films pretty easily - I think you see it in the original MIGHTY JOE YOUNG, when the wrestlers and bodybuilders are about to play tug of war with the giant ape and one shows off by doing it. The thing is, I don't think I've ever seen an FBB do that, even though you'd think it would be as popular as ever (right up there with shirt-ripping and things like that). Maybe I've asked before, but has anyone ever seen this?
