Looking for any exercises to do at home for my almost-7-year-old DD for bent elbows. She is extremely stong - huge arm muscles - but always has bent elbows on handstands, back handspring, and bars. Coach mentioned that it could be that she is so strong in her biceps that she has always relied on those muscles for her skills, so isn't utilizing her other arm muscles, which in effect is causing the bent elbows. Any tips/exercises to help her straighten her arms that we can do at home? Any other ideas as to why she might always have bent elbows? Thanks in advance for any suggestions!!!!
