My daughter (L4 training 5-6) has a great round off back hand spring and round off two back hand springs but whenever she does any back hand spring (standing or in series) her left arm bends. She is making all corrections and trying very hard but it keeps bending. Coaches aren’t worried but also say they don’t want to keep working on higher skills until it’s fixed. She has no problem with her arms on kips, in back walk overs, etc. Any tips? It’s really frustrating her!
