Founder & Chief Executive Officer

It started with a race once around the track in sixth grade in Marlboro, New Jersey.

Raised by a single mother after his father died when he was 8 years old, Jason moved with his family from Brooklyn, New York to the New Jersey suburbs, where he grew up playing baseball and soccer and running track. He may have inherited his love of sports from his mother, who competed in softball, basketball, and the roller derby in her youth and had a career as a high school physical education teacher.

The passion Jason found as a kid for the science of athletic performance placed him on a yellow brick road that he still follows every day. Formally trained as an exercise physiologist by some of the top scientists in the field, he is also a passionate coach, author, speaker, and creator of the REVO₂LUTION RUNNING™ certification, which has been obtained by coaches and fitness professionals in 25 countries.

At age 24, Dr. Karp became one of the youngest college head coaches in the country, leading the Georgian Court University women’s cross country team in New Jersey to the regional championship and winning honors as NAIA Northeast Region Coach of the Year. As a high school track and field and cross country coach, he has produced state qualifiers and All-Americans.

Dr. Karp has given hundreds of talks on women’s training and other subjects at many of the world’s top fitness conferences and coaching clinics. He has been an instructor for USA Track & Field’s level 3 coaching certification and for coaching camps at the U.S. Olympic Training Center.

A prolific writer, Dr. Karp has authored more than 400 articles and 12 books, including The Inner Runner, Running Periodization, Running a Marathon For Dummies, and Running for Women, the bestselling book that he co-authored with sports medicine physician and elite ultramarathon runner Dr. Carolyn Smith, who sits on the Kyniska Running advisory board.

Dr. Karp received his PhD in exercise physiology with a physiology minor from Indiana University, his MBA in entrepreneurship from San Diego State University, his master’s degree in kinesiology from the University of Calgary, and his bachelor’s degree in exercise and sport science with an English minor from Penn State University.

Dr. Karp’s research has been published in several scientific journals, and he serves as a journal expert peer reviewer. He has studied muscle fiber recruitment patterns during eccentric contractions, training characteristics of Olympic Marathon Trials qualifiers, nutritional strategies for post-workout recovery, the relationship between breathing and stride rate in runners, and the effects of the menstrual cycle on running performance, which planted the early seeds for Kyniska Running. He is responsible for the development of Kyniska Running’s training methodologies.

For his contributions to the industry, Dr. Karp has been honored with several awards, including IDEA National Personal Trainer of the Year in 2011 and the President’s Council on Sports, Fitness & Nutrition Community Leadership award in 2014 and 2019. He was also a 2019 finalist for Personal Fitness Professional Trainer of the Year and 2020 finalist for Association of Fitness Studios Influencer of the Year.
