Besides bridges and backbends what are some other at-home drills to safely increase back flexibility for a five year old? My dtrs dance teacher said she needs to 'work' on her backbends. (I find the dance studio is much more aggresive at priming kids for company) I need to get clarification from her but she does her bridges, backbends and splits. The splits she works on every other day (for dancing) but the bridges, backbends she does daily - it seems as though some kids just naturally have a great arch to their back and some don't.
