Curling, arching, twisting should be done almost daily, or at least whenever that all-too-familiar stiffness creeps into the spine.
Daily stretches rarely last more than 5 minutes. They are superficial but take the edge off. One full yoga class a week is required to make any real progress. Then those quickies on the road take on a real significance.
Yoga isn’t just about limber joins. It’s about calming the nervous system. You learn a tool for unwinding anxiety. You learn to breathe, meditation. You step back from the assertive pursuits of life, and experience acceptance and receptivity.
Yoga is a healing art. And a science. Don’t deny yourself the pleasure.
