During his time at U of T, Pasternak served as a Nutrition and Exercise Scientist at Department of National Defence's DCIEM (Defence and Civil Institute for Environmental Medicine) from 2005-2007. As a scientist, Harley focused on performance physiology and nutrition, with a specialty in caffeine and ephedrine.

Personal training[edit]

As part of his personal training, Pasternak has worked with many celebrity clients, including: Jennifer Hudson, Lady Gaga, Kim Kardashian, Kanye West, Megan Fox, Bono, Milla Jovovich and Alicia Keys.[3][4][5]

In 1999, Dr. Marvin Waxman introduced Pasternak to producer Don Carmody, who hired Pasternak to work with Jim Caveziel and cast on his film, ‘Angel Eyes’.[6] After several subsequent films, Carmody hired Pasternak to train Halle Berry, Robert Downey Jr., and Penélope Cruz on the set of 'Gothika' in Montreal.17 Berry suggested Pasternak move permanently from Toronto to Los Angeles to continue to work together, which he did.[7][8]

In 2004, Berry played the title role in Catwoman, a role for which she trained exclusively with Pasternak. Berry's fit body made headlines which in turn led to a great deal of press word-of-mouth about Pasternak's physical training and nutrition advice. Press coverage included The Oprah Winfrey Show, where Pasternak was invited to discuss how he helped her get into shape.1[9] Winfrey suggested that he write a book about his program.[7][8][10] The book, 5-Factor Fitness: The Diet and Fitness Secret of Hollywood's A-List was published in 2005 and became an international best-seller.


In addition to his hosting on The Revolution,[11] Pasternak has made multiple appearances on American and Canadian morning daytime talk shows and news programs, along with serving as a guest judge on Germany's Next Topmodel and Canada's Next Top Model. In January 2017, Pasternak appeared on Khloe Kardashian's series "Revenge Body".


Pasternak appears as himself doing a fitness routine with Megan Fox in the 2014 Teenage Mutant Ninja Turtles film.[12] He also appeared as himself as Jessica Simpson's personal trainer in Private Valentine: Blonde & Dangerous in 2008.


Pasternak has published four books, which have been listed on the New York Times bestselling list and been published in fourteen languages, with sales in 29 countries.
