I have been coaching level 4 for a few years now and am having a problem with my new level 4's that I've never had. They have all their skills but almost all of the girls have peeled off jumping to high bar at least once. The bars are close enough, and they are jumping hollow but still peeling off. When I watch, I really don't see an error. Is there something I could be missing? Any tips? I've been standing there for a few weeks now just in case, but ideally I don't want to have to stand there during meet season. Any help is appreciated thanks!
