Face in the water and body streamlined. As the palms face inwards to finish the heart-shaped pattern close to the body, the shoulders are pushed up and the face clears the water. The swimmer breathes, the hands drive forward, the face re-enters and the swimmer stretches into the streamline position. Repeat the pattern. Have the swimmer repeat correctly for 10 pulling strokes and then build up to 1 length of the pool, and so on as long as the pulling pattern does not deviate from the pattern.
Good habits are important in learning to swim correctly.
