Stand straight with your feet shoulder width apart.
Place your right hand behind your head and your left hand on your hip. In one movement, move your right elbow and your left knee to put them together while your exhale. Return to the starting position with a smooth movement while you inhale. Repeat the movement for the specified amount of repetitions and then switch sides and repeat with the other arm and leg.TIPS: The exercise key is quality over quantity. The trick is to perform the exercise using proper form.
