Stand up straight with a resistance band attached at shoulder height to a sturdy object.
Hold the other end in your hand on the side to be exercised.
Step the leg on this same side backwards and turn your body to the side.
Your feet will point diagonally.
Lift both arms up to shoulder height.
Pull the arm with the band backwards leading with your elbow.
Ensure your arm stays up at shoulder height but be conscious not to hunch your shoulders up.
Follow the movement of this arm with your head.
Control the movement as you return to the starting position and repeat.
