If building firm, well-toned muscles is your principal goal in exercising, it is not as if your selection is limited. There are dozens of different routines that can strengthen your muscles and help you mold a pleasingly contoured physique. This book is designed to revitalise your exercise programme by presenting a series of harder-than-average workouts that have been designed to require little or no equipment, and - as you will find is explained in the book - that offer distinctive ways of taxing or overloading your muscles. Some are advanced variations on familiar muscle-strengthening calisthenic routines; others show new ways to sequence exercises in a manner that makes the total workout more demanding to perform; and finally, there are techniques for developing power, an aspect of fitness related to muscle strength and tone.
