Bhujangasana, or the Cobra Pose, helps increase the lung volume, stretch the thoracic muscles, strengthen your abdominal muscles, and improve your posture:
- Lie on your stomach and inhale deeply. Slowly raise your torso, and keep your lower body to the floor at the same time. Balance on your legs and arms.
- Raise your head and look up.
- Slowly breathe out and assume the initial position. Try increasing the time you stay in the pose with each repetition.
