I enjoyed learning the history of the creative director of this wonderful workout. I had been invited to attend a lesson by a friend and was immediately hooked. I now go three times a week. The music, the dances and the camaraderie of the other people in class is exhilarating. It is the most fun I ever had while exercising. And the bonus from this wonderful workout is that it charges up your metabolism and the pounds drop off. The only problem is with the DVD. It has only a few basic dance steps. I want more, more and more. Beto Perez is the man to thank for writing this great book and giving us an insight into his interesting life story.
