This is a great exercise for relieving stiffness in the lower back.
Start by sitting on a ball or chair with your back straight. Keep your feet about hip width apart and have your hands resting very lightly on your thighs (no pushing on your legs). Exhale, pull your belly button toward your spine and flatten your low back. It may help to imagine yourself tucking your bum or tailbone under.
Inhale and slowly bring your tailbone back until you have a slight curve in your low back. Repeat this exercise 10-12 times, focusing on posture, engaging your core, and proper breathing.
