Flat Back Rotation
This arabesque exercise combines balance, rotation and length in a flat back. The working leg reaches back while the arms reach forward, resistance in opposition.
In the lunge, lengthen the top of the head forward and the back heel back. Think top of head to foot rather than nose to knee. Flex the whole foot, not just the toes.
As the leg turns from arabesque to parallel second, it reaches out of the hip rather than getting stuck in it.
