Wasn't sure whether to post in mobility, skill or rings...
My lack of experience with technical gymnastics is showing again. I've been thinking about these lately, and someone was asking me the other day, then the video of Josh Naterman doing them came up again, so I took it as a prompt to ask. If someone in the know has a moment to enlighten me, I'd really like to know more about these, their requirements/use in developing conditioning&flexibility, etc.
I will also accept 'Stop thinking about these until you're concentrating on rings strength' if that is the correct answer
but I would also much appreciate knowing more about them even if it's prefaced by that.
Thanks much,
Jon
