People doesn't say the origin

 Of aerobic exercises, my mother had a book that she used for lose and postural correction, and the book was the exercises that was developed for the army of USA, I think that was in the 40's. Have perfect bodies all exercised. Everything have the origin, was a book with pictures are type heavy, but is a long time, make all with repetition of 20-50 would be all muscle building. I think that the objective is work all the muscle even of the neck and back to have a perfect body, that is all proportional.
