I started Critical Alignment a few years ago to act as a chiropractic treatment for my spine. It is the best practice for helping your body work through various spinal and posture issues. I bought the high quality spinal strap from Cat Yoga Props and I am so happy I did. It feels like a deep massage and chiropractic treatment. It is well worth the money to have this simple yet super effective strap to bring to classes and use at home. You can bring it everywhere!
