Paul Laursen, PhD is an athlete, author, endurance coach, high-performance consultant and entrepreneur. He's published over 125 peer-reviewed papers in exercise and sports science journals, and his work has been cited more than 8,000 times. We've had Paul on the podcast before to talk about High-Intensity Interval Training (HIIT), as described in his book and brought to life in his online course.

On this podcast, Paul describes how he's taken HIIT training to a new level by creating the Athletica software, to help athletes train smarter, not harder. Using the principles in his book, this software can adapt a plan based on your current fitness levels, goals, training sessions and life. As an athlete and software developer, I couldn't resist asking Paul some tough questions about how it all works.
