Today another cooperative podcast between Chris DeSantis Coaching and Proswimworkouts, we got an Olympic coach to weigh in on Test Sets. Why do we use them? What are they fore? And what are they exactly?

Paul Yetter goes deep, including an explanation of how Jon Urbanchek's color charts helped him to become a better coach in 2006 and ways you need to scale what you measure to different types of swimmers.
