Stand up straight.
Relax your arms by your side and bring your legs and feet together.
Starting at the top of your head, tuck your chin into your chest.
Round the top of your back and your shoulders.
Allow your arms to dangle directly down towards your feet.
Continue rounding your back one vertebra at a time.
Keep your weight in the balls of your feet, allowing your hips to push back slightly behind you.
Once you have reached the point where you have a uniform curve from the top of your spine to the base, control the movement as you return to the starting position.
Ensure you reverse the movement, straightening one vertebra at a time.
