Tudor O. Bompa, PhD, revolutionized Western training methods when he introduced his groundbreaking theory of periodization in his native Romania in 1963. After adopting his training system, the Eastern Bloc countries dominated international sports through the 1970s and 1980s. In 1988, Bompa began applying his principles of periodization to the sport of bodybuilding. He has personally trained 11 Olympic medalists (including four gold medalists) and has served as a consultant to coaches and athletes worldwide.

Bompa's books on training methods, including Theory and Methodology of Training: The Key to Athletic Performance and Periodization of Training for Sports, have been translated into 19 languages and used in more than 180 countries for training athletes and educating and certifying coaches. Bompa has been invited to speak about training in more than 30 countries and has been awarded certificates of honor and appreciation from such prestigious organizations as the Ministry of Culture of Argentina, the Australian Sports Council, the Spanish Olympic Committee, NSCA (2014 Alvin Roy Award for Career Achievement), and the International Olympic Committee.

A member of the Canadian Olympic Association and the Romanian National Council of Sports, Bompa is a professor emeritus at York University, where he taught training theories since 1987. In 2017, Bompa was awarded the honorary title of doctor honoris causa in his home country of Romania. He and his wife, Tamara, live in Sharon, Ontario.
