Lie on your back.
Bend your legs, keeping your knees and feet parallel at hip width apart and your arms by your sides.
EXHALE: rotate in your hip and slowly open one leg outwards with your knee reaching toward the mat.
INHALE: bring your knee back in line with your hip.
Repeat with the same leg.
Keep your knee at a consistent angle and in line with your opposite knee as you rotate in your hip joint.
Maintain a stable pelvis and use your adductors to bring the knee back to the starting position.
