Sasangasana, also called the Rabbit pose, is a simple pose with great benefits.
Sitting on Child pose, holding on your heels, rest the crown (top) of your head in front of your knees, then lift your hips as high as possible, until arms are straighten. Feel your spine curved and elongated, chin tugged to chest.
Benefits: relieves mild head, neck, and back pain; lengthens spine and stretches back, arms, and shoulders; maintains mobility and elasticity of spine and back muscles; improves digestion; aids insomnia.
Each time after a Rabbit pose, I release my forehead on the mat, come back to Child pose and rest for a few breathes before sitting up to avoid dizziness.
