Strength athletics is the collection of strength sports which measure physical strength, based on both: non-standard and historical implements as seen in Strongman and Highland games, and standardized and calibrated equipment as seen in Powerlifting and Weightlifting. Some of the disciplines have similarities to each other and although it is very difficult to master more than one, some athletes participate in several of them and perform at world class levels.
