I Am Reading
he Nautilus Bodybuilding Book by Ellington Darden Ph.D.
As the title suggests, the books focuses on bodybuilding, using H.I.T. techniques. It also includes some history of Nautilus and some of the science to back up the many claims.
Darden is an H.I.T. proponent, who spent many years working with Arthur Jones, the eccentric genius who single-handedly invented Nautilus weight training machines, and transformed the fitness industry.
The book is old, published in 1982, but the info is still valid and useful, particularly if you indulge in High Intensity Training.
You can pick up a copy quite cheap on Amazon.
