In revising Get Fit, Stay Fit, my developmental editor Gary O’Brien has been instrumental in the development of the seventh edition and has provided a great deal of help and support. He is an integral part of all of my textbook projects, and I rely heavily on his expertise, his persistence, and his patience with me.
As always, this is for my wife Tena and our boys, Brian and Zach, who each day make my life more worthwhile.
