Bodybuilding is the process of maximizing muscle hypertrophy through the combination of weight training, sufficient caloric intake, and rest. Someone who engages in this activity is referred to as a bodybuilder. As a sport, called competitive bodybuilding, bodybuilders display their physiques to a panel of judges, who assign points based on their aesthetic appearance. The muscles are revealed through a combination of fat loss, oils, and tanning (or tanning lotions) which combined with lighting make the definition of the muscle group more distinct. Famous bodybuilders include Arnold Schwarzenegger, Dorian Yates, Lou Ferrigno, Franco Columbu, Frank Zane, Lee Haney, Ronnie Coleman, and Jay Cutler.
Early years:
Although audiences were thrilled to see a well developed physique, those men simply displayed their bodies as part of strength demonstrations or wrestling matches. Sandow had a stage show built around these displays through his manager, Florenz Ziegfeld. He became so successful at it, he later created several businesses around his fame and was among the first to market products branded with his name alone. As he became more popular, he was credited with inventing and selling the first exercise equipment for the masses (machined dumbbells, spring pulleys and tension bands).On 16 January, 1904, the first large-scale bodybuilding competition in America took place at Madison Square Garden in New York City. The winner was Al Treloar and he was declared "The Most Perfectly Developed Man in the World". Treloar won a $1,000 cash prize, a substantial sum at that time. Two weeks later, Thomas Edison made a film of Al Treloar's posing routine. Edison also made two films of Sandow a few years before, making him the man who made the first three motion pictures featuring a bodybuilder.
The "Golden Age":
The period of around 1940 to 1970 is often referred to as the "Golden Age" of bodybuilding because of changes in the aesthetic for more mass, as well as muscular symmetry and definition, which characterised the "early years". This was due in large part to the advent of World War II, which inspired many young men to be bigger, stronger and more aggressive in their attitudes. This was accomplished by improved training techniques, better nutrition and more effective equipment. Several important publications came into being, as well, and new contests emerged as the popularity of the sport grew.
1970s onwards
In the 1970s, bodybuilding had major publicity thanks to Arnold Schwarzenegger and the 1977 film Pumping Iron. By this time the IFBB dominated the sport and the AAU took a back seat.
