Cat Cow Pose
http://www.youtube.com/watch?v=C7BrKMcQeOc
Stay on all fours,arms straight below your shoulders,hips over
your knees,look straight ahead, round your spine upward like a
camel's hump,as you drop your tailbone and lower your head,
inhale and let your belly drop,arch your back down and lift your
head and tailbone, continue in sequence a few times.
This exercise increases the spinal flexibility and relaxes the lower
back.
