I would like to express my gratitude to all those who have helped me in the production of this book.
Professional help has been offered above all by Simon Bourne and Mark Raiss, my former colleagues and now directors of the Benaim Group, who in the midst of very busy schedules, found time to read attentively many of the chapters, make thoughtful, constructive comments, and check my mathematics in detail.
In my quest for attributable images I have been dependent on consultants' and contractors' staff searching back in their records for jobs, some of which are thirty years old, and I would like to thank all those who helped me in this way. In particular I would like to thank Pauline Shirley of Arup's library for her patience and helpfulness in identifying and making available photographs of the Runnymede Bridge and the Byker Viaduct, among other projects. I would also like to acknowledge the kind assistance of the librarians of the Institution of Civil Engineers.
As it is hoped that this book will be read by the technically minded who are not trained as engineers, I am grateful to my son David for his 'lay' reading of the early chapters, and for his constructive and helpful comments.

The use of dumbbells gives you a much more comprehensive strengthening effect because the workout engages your stabilizer muscles, in addition to the muscle you may be pin-pointing. Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
