https://www.youtube.com/watch?v=1K-TyBctOok - helps improve your arabesque, stretches your hips, thighs, and back https://www.youtube.com/watch?v=i6TzP2COtow - says its a full body stretch routine, but I would say it would help deepen your split, as it mainly stretches your lower back and legs. https://www.youtube.com/watch?v=4gISxG1NNnI - full body mainly, but if I had to choose one thing, this definitely will help with your extensions and arabesque. (i am trying to stretch everyday, so will hopefully update tomorrow when i find another vid!)
