Development exercise for the legs.

Stand with your feet together. Throughout the exercise maintain a Neutral Spine Position, keep your head up.

Take one full step forward. With the weight balanced between the ball of your rear foot and the heel of your forward foot and keeping your body in an upright position, bend your knees until your rear knee is just above the floor.  Do not let the knee of your front leg push further forwards than the toe of your front foot.

Raise yourself up by straightening your legs, and step backwards so that your feet are together.

Repeat the exercise stepping forwards with the opposite foot. Continue, alternating the forward foot.
