What your mental images denote is the competitive sport of professional bodybuilding, an enormous, billion-dollar industry that is generally more about physique than strength. Professional bodybuilding is an art form, perfected through years of heavy lifting, excellent nutrition, expert guidance and unwavering dedication. One of the most well-known body-builders of our times is Arnold Schwarzenegger, the Austrian-American who went on to become Governor of the State of California. Although prize-money can reach into the millions for elite competitions, making money from bodybuilding is incredibly difficult. Most athletes don’t make enough to live on, instead using it to supplement their income. In many cases, successful athletes live on sponsorships from gyms and supplement companies, and others get into the lucrative business of personal training.
