1 - Begin on all fours in a tabletop position with your wrists directly under your shoulders and your knees under your hips.
2 - Keep your core lightly engaged and your spine in a neutral position.
3 - Inhale and raise your right arm up toward the ceiling, opening your chest to the right side.
4 - Exhale and slowly slide your right arm underneath your left arm, palm facing up, allowing your right shoulder and the right side of your head to lower to the mat.
5 - Hold the stretch, breathing deeply, feeling the rotation through your thoracic spine and the opening across your shoulder and upper back.
6 - To release, inhale and slowly retract your right arm, returning to the tabletop position.
7 - Repeat on the opposite side, threading your left arm under your right arm.
