Strongman refers to one who competes in strength athletics - a more modern eclectic strength competition in which competitors lift rocks, tote refrigerators, pull trains, walk while towing an eighteen wheel truck behind them, etc. The most famous competition of this type is World's Strongest Man and the " World's Strongest Man Super Series", however North American Strongman, Inc. (NAS) holds amateur and other meets throughout the United States. In recent years, interest in the sport at the grassroots level has skyrocketed, leading to the spontaneous formation of local clubs, loosely affiliated with provincial/state and national associations.
Many sports-specific training facilities have begun to incorporate movements associated with strongman competitions into their general training schemes, albeit with lighter weights used; e.g. tire flips, sled drags, object loading or carrying, log pressing, farmer's walks and so on.
