As a professional Sports Medicine Practitioner and Yoga teacher its is all too often I see patients with lower back pain. Here is a sample of some of the common yoga stretches/movements I use both for patients and in Yoga classes I teach. Note there are other things that will support a health back including learning how to use your deeper core muscles (Transverse Abdominals) in yoga this relates to the uddiyana bandha (located at or near the navel and means to bind. It is best to work with a trained professional who can teach techniques to strengthen the Transverse Abdominals or a Yoga Teacher who can teach you how to use the concept in your practice.
This guide is purely based on stretches that done daily will help you improve the strength, mobility and flexibility of the body supporting the low back and spine. Yes, there are many other poses/movements that will help and I encourage you to listen to your body and do what works and make it a regular practice.
Please feel free to share. Also, you are welcome to reach out and email me with any questions.
Warmly, Joe Sarti
