Research has shown that cyclists, runners, triathletes, and other endurance athletes improve the most when they consistently do 80 percent of their training at low intensity and the other 20 percent at a moderate to high intensity. Matt Fitzgerald, co-author of the new book "80/20 Triathlon" explains what 80/20 training is all about and answer commonly asked questions.   IN THIS EPISODE YOU'LL LEARN ABOUT: -What Matt would put on a t-shirt if he had to distill 80/20 Triathlon down to a very short and concise slogan -The proper planning and the proper execution of 80/20 training -Is there "wiggle room" in the 80/20 percentages? -Should you apply 80/20 within each discipline or simply across all your training? -The most common mistake age-groupers make: not executing the easy training easy enough -How is easy, moderate, and high intensity percentages calculated? -The difference between 80/20 training and polarised training -What to do with the 20% of moderate to high intensity   SHOWNOTES: https://scientifictriathlon.com/tts104/   THAT TRIATHLON SHOW HOMEPAGE: www.thattriathlonshow.com   SPONSORS: Precision Hydration - One-size doesn't fit all when it comes to hydration.
