My little one, who just turned 6 years old, learnt her back handspring 2 weeks ago. When she is spotted (with just a one hand spot) she keeps her legs together and straight. On her own she tends to keep them open and bent. As well she doesn't seem to push back as much as she does when spotted. Are these things that will improve with time and experience? Are there any hints or exercises I can give her that might help her.
