Start each day with a few rounds of Cat (Marjaryasana) and Cow (Bitilasana) pose.
Linking your breath to the movement, inhale as you arch the spine and exhale as you round the back.
This is a great way to stretch the spine and hips, open the chest, and bring awareness to the abdominal muscles. Also, a great mid-day break if you sit at a desk for long hours! You can even do it standing with your legs slightly bent and your hands resting on your thighs.
