I started doing ring training at a different gym than I used to. When doing iron cross on these rings, it feels different from the other rings I used to do them on (the other gym had 3 pairs of rings and they all felt fine). These rings seem as if they wiggle when I start lowering into iron cross, and because of that my muscles don't feel as though they're working properly. I don't know why it'd feel like this and if my muscles might adapt to it in time, or if these rings are just set up weird causing unpredictable instability that my muscles won't be able to adapt to very well.
Front levers and back levers feel fine, just iron cross is a problem. Is there a reason rings would feel weird like this? Is it worth still training on these rings?
