Extend your arms out to the sides at shoulder height and twist your torso to the right.
As you exhale, bend forward and reach your left hand towards your right foot as if you are "sawing" off your toes, keeping your right hand behind you for balance.
Inhale and sit back up, untwisting your torso to return to the starting position.
Repeat the movement on the other side by twisting your torso to the left and reaching your right hand towards your left foot.
