Paul Laursen, PhD is an author, endurance coach, high-performance consultant and entrepreneur. He has competed in 17 Ironman triathlon races and has published over 125 peer-reviewed papers in exercise and sports science journals. We've had him on the podcast once before to discuss High-Intensity Interval Training (HIIT), and he's since co-authored a book and developed an online course on the topic.

In this podcast, Paul and I take an even deeper dive into HIIT, including the specific physiological benefits that just aren't available with lower intensity aerobic training. He describes his book and training course, which bridge the gap between the science and application of HIIT. We also get into some of the technology, gadgets, and sports psychology concepts that Paul uses in his coaching.
