If you had taken ballet first as most better recreational schools require, doing a split wouldn’t be a problem. You skipped taking the technique classes required to dance contemporary dance. Flips are not generally part of contemporary dance. However you need to be able to do whatever the choreographer wants. That’s why you need years of ballet and codified modern dance technique training first.
