About Us
Bridging The Gap Between Science And Practice
As self proclaimed, “failed athletes”, founders Paul Laursen and Martin Buchheit, recognized that they weren’t the most gifted athletes but may have been able to out train the competition with proper coaching — by training smarter, not harder.
This sparked a lifelong search for knowledge into exercise science and human performance.
HIIT Science is now a collaborative community of experts across the globe focusing on bridging the gap between science and practice, teaching coaches how to program based on a full understanding of the human body and systems that maximizes athlete performance.
