One of the things that I love about Pilates is that it helps us focus in on our alignment. Alignment, along with core control, is key to maintaining balance and avoiding pain, which are both Good Things.
Some questions to ask ourselves to encourage alignment:
What are my shoulders doing right now?
Where is my pelvis? Is it tilted forward or back? Is one side higher than the other? More forward?
What about my head? Am I looking up or down? Do I always tilt it one way or the other?
First we notice, then we correct.
