with Webster. When Webster retired from his position, Edmunds took over. These two men were responsible for inviting the competitors and choosing the events. They selected men who had shown prowess in the mainstream fields of strength sports and field athletics events, such as shot put, American football, powerlifters, bodybuilders and wrestlers. The idea was to create a spectacle that would test competitors against one another. The show was enough of a success that it began to be replicated in other countries, such as Britain's Strongest Man (1979). Competitors began shifting from unpaid amateurs to professional strongmen. By the end of the 20th century, and in to the 21st, other strongman programs and events were created such as Strongman Championship hosted by comedian Errol Silverman. Other competitions have been televised, such as the World Muscle Power Championships, World Strongman Challenge, Arnold Strongman Classic, Giants Live, Highlander World Championships, World Strongman Federation, and Europe's Strongest Man. Common disciplines There is no set rule about what specific events will occur in a contest, except that to prevent single-event specialists from gaining an advantage, each event will be different (a single contest will not include two squat events, or two overhead lifting events, for example). Normally, a strongman contest comprises five or six events, though at the top level of competition, seven or eight events may be held. Among the most common events are: Farmer's Walk – competitors race along a course while carrying a heavy weight in each hand. A variation is the Giant Farmer's Walk, with a much heavier weight carried over a shorter distance. Hercules Hold or Pillars of Hercules – contestants stand between two pillars, pivoted to fall outwards. The competitor must simply hold them up for as long as possible. Vehicle pull – competitors pull a vehicle from a stationary start for a prescribed distance – fastest over the course wins. Trucks are commonly used, but larger spectacles employ trains, boats, and airplanes. Atlas Stones – a lifting stone event whereby five spherical concrete stones of increasing weight are placed on top of podia of varying height, beginning with the lightest stone lifted to approximately a normal person's head height. Alternatively, the stone is lifted over a bar for reps. Stone Carry – in Iceland, the original stone carry was performed with the Húsafell Stone, that was to be carried for a stretch to achieve the title fullsterkur
