3. The body must be kept perfectly on the breast, and both shoulders in the horizontal plane.

Up and sown movements of the legs in the vertical plane are prohibited. All movements of the legs and feet must be simultaneous, symmetrical and in the same lateral plane. A contestant may not introduce a side-stroke movement, or use the top of the instep of one or both feet in the propulsive part of the breaststroke kick.
