This Exercise is intended to correct imbalances in the breath and musculature of the ribcage and spine.
To do this exercise you will need a mat. Start by lying on your back with your knees bent and your feet planted in the ground. Then place one hand on one side of your ribcage. As you inhale try to spread the ribs underneath your hand without moving the ribs on the other side. As you exhale feel the ribs move away from your hand. Repeat 6-8 times on each side.
Things to think about
This is not an exact science. It is tremendously difficult if not impossible to isolate the breath in just one lung, but the act of trying to isolate the breath can increase the stretch in the musculature of the ribs that are moving.
