Use two facing each other floor pulleys with loop handles. Grasp the left handle with your right hand and the right handle with your left hand.
Stand with your feet about shoulder wide between the pulleys, bend your knees slightly. Bend forward at the waist until your torso is parallel with the floor. Cross your arms as far as you can.
Keeping your torso still, raise your arms to the sides until your hands are slightly above your shoulders. Your palms should be facing the floor. Keep your arms perpendicular to your torso and a fixed elbow position (10 to 30 angle) throughout the exercise.
Hold this position for a moment and slowly lower your arms back.
