Lying face down, with your hands under your shoulders, but not touching the mat,
gently lift your head and shoulders
as far as you can without stress. Look at the end of your mat, to avoid straining your neck.
Hold this position while you breathe deeply for a few breaths. See if
you can feel the movement of your breath against the floor.
Start by doing a Baby Cobra, then put your hands on the mat and push up further.
(If you have wrist issues, use your forearms.)
Continue to look at your mat. Keep your shoulders
down, away from your ears. Keep breathing! This is a diaphragm-stretching
exercise. As you inhale, feel the expansion of your torso against the floor.
Deep breathing here is far more important than how high you bend.
