Welcome!

Welcome to the new website for Drake University’s Exercise Physiology class! This website is designed to highlight the work students have done researching and writing about topics related to exercise training and performance, fitness, health, physiology, and nutrition. Each blog post is reviewed for content and accuracy by peers in the class and by the instructor. Our goal is for this website to be a platform for our students to provide current, interesting, and scientifically-informed exercise physiology content written for a general audience.
