There is no definitive answer to this question as it largely depends on how you define and measure “richest.” However, if we look at the estimated net worth of some of the world’s most successful bodybuilders, Arnold Schwarzenegger is likely at the top of the list.
Born in Austria in 1947, Schwarzenegger started his lifting career while still in his teens and won his first Mr. Olympia title in 1970 at the age of 23. He would go on to win the prestigious title a total of seven times throughout his career. In addition to his success in competitive bodybuilding, Schwarzenegger has also enjoyed a very successful acting career, starring in such blockbuster films as The Terminator series, Predator, and True Lies.
All told, Schwarzenegger’s estimated net worth is somewhere around $400 million dollars. This puts him well ahead of other wealthy bodybuilders like Ronnie Coleman ($10 million), Jay Cutler ($30 million), and Phil Heath ($8 million).
