Keep your spine strong and flexible! Modify the limbs in order to protect the spine. Bend your knees in forward folding poses and try to extend your spine as you fold deeper into the pose. This will protect your low back and deepen the stretch in the back of the legs. Yoga is really good at getting nutrients to the spinal discs. There’s no blood supply after about the age of twenty-five. Backbend poses, forward folding poses, twisting poses, and inversions, are all great ways we can squeeze the discs and give them nutrients. Just be mindful. An injury to the spine is a much bigger deal than an injury to other areas of the body.
