Spine stability is important to maintain so that your spine is strong. Here are some things you can do to enhance your spine stability:

• Maintain spine flexibility: Engaging in physical activity and stretching helps to strengthen your spine which reduces the risk of injury and promotes spine stability. 
• Lumbar stabilization exercises: Lumbar stabilization exercises work your lower back and abdominal muscles which help to provide stability to your spine. Some exercises you can do are pelvic tilts, arm/leg raises, and hamstring stretches. 
• Thoracic spine mobility exercises: The thoracic part of the spine is the middle of your spine. Improving mobility in the thoracic part of your spine can help to improve stability in the whole spine. You can try the open book stretch and cat-cow stretch.
