An excerpt from Weight Training for Old Guys, the only weight training book you'll ever need:
A skinny guy doing curls, another guy wrestling with cables, and another one grunting on the leg extension machine. Ah, the sights and sounds of a modern gym! Most of the things people do in a gym is a waste of time! Yes, performing isolation exercises, working small muscles, and pushing and pulling on the latest machine will never produce the results gym-goers so doggedly seek. Never. You simply can't develop your overall physique by working small muscles individually or by doing highly specialized exercises. Most gym-goers work relatively small muscles or perform exercises that attack a narrow area of their physique and then wonder why their physique hasn't changed that much - if at all.
