1. Improves your flexibility

3. Perfects your posture
4. Prevents cartilage and joint breakdown
5. Protects your spine
Spinal disks—the shock absorbers between the vertebrae that can herniate and compress nerves—crave movement. That’s the only way they get their nutrients. If you’ve got a balanced asana practice with plenty of backbends, forward bends, and twists, you’ll help keep your disks supple.
6. Betters your bone health
It’s well documented that weight-bearing exercise strengthens bones and helps ward off osteoporosis. Many postures in yoga require that you lift your own weight. And some, like Downward- and Upward-Facing Dog, help strengthen the arm bones, which are particularly vulnerable to osteoporotic fractures. In an unpublished study conducted at California State University, Los Angeles, yoga practice increased bone density in the vertebrae. Yoga’s ability to lower levels of the stress hormone cortisol may help keep calcium in the bones.
7. Increases your blood flow
