Compression fractures of the vertebrae and formation of bone spurs are very common. As you age your vertebrae become thinner and weaker. This is due to the loss of some of their mineral content, which causes your spinal column to become curved and compressed (packed together).
Keeping your spinal column healthy and strong is very important. High-impact weight-bearing exercises like jumping rope, where you move against gravity while staying upright work best for strengthening your vertebrae.
