The answer is: Yoga.
It will stretch and align your spine.
It will restore flexibility and range of motion.
It will strengthen and tone.
It will help you to “just be”, and be “in the moment”. Well, honestly, that part hasn’t worked particularly well for me.

I had some pain in my lower neck, from arthritis. It was like a permanent crick in my neck, it had been there for years, and my range of motion was limited. I started doing yoga, and within 6 weeks, the pain was gone. I’m still doing yoga, my range of motion has improved, and the pain is still gone.
