Lumbar Spinal Twist
While laying flat on your back and feet flat on the floor, extend your arms out to your sides. Bend both knees upward together and roll them to your right side. Hold this position for 10 seconds and then return to starting position. Repeat this going to the left side.
You should avoid any exercise which causes you to have increasing pain or other symptoms. Consult with a medical professional before beginning any exercise program.
