He was already a fast freestyle swimmer with a thudding kick when he went to Xalapa to study law and to be coached in swimming. In 1956 he learned the butterfly (swimming), butterfly stroke under the guidance of his trainer Antonio Murrieta and watched an exhibition of the (by that time) "new dolphin kick" technique by the experienced swimmer Walter Ocampo, of Mexico City's Centro Deportivo Chapultepec.
