This book is an introduction to building physical strength.

Strongmen were very popular as performance artists in circuses, sideshows, and later vaudeville performing seemingly impossible feats of supernatural strength. Some strongmen, such as Steve Reeves and Reg Park (later known as bodybuilders) adapted with this changing times and moved to film playing roles such as Hercules and Goliath paving the way for the musclemen like Arnold Schwarzenneggar who would go on to dominate the film industry and become international superstars for their incredible bodies.
This book goes over the early history and feats of strongmen as well as providing an early guide to physical fitness and exercise which is still mostly relevant today for those interested in building powerful physics.
