Lloyd Percival (June 3, 1913 – July 23, 1974) was a Canadian sports coach, author, and fitness guru.
[1] In addition, he became a leading track and field coach in Canada, a position he maintained into the 1960s,[4] having founded the North Toronto Red Devils club in 1946.
[6] Isometric exercise was a form of workout favored by Percival, along with mental training; The Globe and Mail's Lorne Rubenstein wrote that "he wanted the mind and body allied as one under the objective of getting the most out of oneself.
On the Canadian Broadcasting Corporation (CBC) radio network, he hosted a program called The Sports College on the Air, which at one point attracted listening audiences of 800,000 people.
[1] In addition, the national teams of Czechoslovakia, Finland, and Sweden were said to have used Percival's book to aid in player development.
Author Gary Mossman wrote that "Percival was never released from the purgatory to which NHL coaches and officials relegated him for daring to challenge their knowledge of the game.
By the early 1970s, Percival began to receive greater recognition; the Canadian Olympic Association hired him as a consultant.
