Begin in a kneeling position with your big toes together and knees comfortably apart.
Sit your hips back onto your heels and slowly lower your chest toward the floor into child’s pose.
Extend one arm (e.g. left) straight out in front of you on the floor, palm facing down.
Gently place your opposite arm (e.g. right) behind your lower back or rest the back of your hand against your sacrum.
With your reaching arm, slowly walk your fingers further forward until you feel a stretch along the side of your torso and underneath your shoulder blade.
Keep your forehead relaxed down on the mat or supported on a cushion.
Focus on breathing into the ribs on the stretching side to enhance the stretch.
Hold/maintain as prescribed by your physiotherapist.
