How to Spot Fitness and Wellness BS with Exercise Scientist Nick Tiller, PhD
About this episode
Dr. Nick Tiller discusses the misconceptions in fitness and wellness, particularly in ultrarunning and sports science.
Dr. Nick Tiller is an exercise scientist at the Lundquist Institute at Harbor-UCLA, a two-decade ultrarunner, and the author of The Skeptic's Guide to Sports Science and the new The Health and Wellness Lie .
