My DD just turned 7 and is a level 4 gymnast. She is quite coordinated and can do all the skills, but she struggles with good form, mostly because she is very hyper mobile (legs and arms both overextend). Body tightness has always been difficult for her, she can tighten, but she has to think a lot about it. Any tips? Has anyone ever coached or had a gymnast like this? Can she overcome this weakness?
