I'm looking for suggestions on improving my daughter's standing back handspring at home. When spotted (and I'm barely touching her), She has perfect form. However, when she does them alone, her knees are always bent and sometimes legs far apart. She can remember to keep her legs together while holding a bean bag between her knees but the knees are still bent. My fear is developing bad habits. Should she only do BHS correctly while spotted and skip doing them solo until she can keep her legs straight? What are some tips for keeping them straight? She is 5 years old and pre-team.
