How to do the Side-Lying Open Thoracic Book

  1. Starting Position:

    • Lie down on your side on a comfortable surface, like a mat.

    • Ensure your body is aligned straight from your head to your feet.

  2. Leg Positioning:

    • Bend your knees at a 90-degree angle and keep them stacked on top of each other.

    • Your feet should be in line with your hips.

  3. Arm Positioning:

    • Extend your bottom arm out in front of you on the ground, shoulder height.

    • Keep your top arm bent at a 90-degree angle, fingertips resting on your chest.

  4. Movement:

    • Inhale deeply.

    • As you exhale, slowly rotate your upper body, opening up your top arm toward the ceiling while keeping your legs stacked.

    • Allow your upper body to follow your arm in a twisting motion. Your gaze should follow your arm as it moves.

  5. Stretch:

    • Hold this position for a few seconds, feeling the stretch through your chest and shoulders.

    • Ensure your knees stay together and in contact with the ground.

  6. Return:

    • Inhale, and gently bring your top arm back across your chest to the starting position.

    • Repeat the movement 5-10 times on this side.

  7. Switch Sides:

    • After completing the repetitions, carefully flip over to the other side and repeat the exercise.

Tips:

  • Maintain a slow and controlled movement to fully benefit from the stretch.

  • Focus on breathing throughout the exercise to enhance relaxation.

  • If you feel any discomfort in your back or shoulders, adjust the movement or stop as needed.
