Ray Gowlett is a professional MMA fighter, motocross racer and research skeptic.His lab contains almost 600 subjects (it's a high school) and Ray is constantly seeking new ways to teach and coach. Many of these kids are high-level athletes; just as many don't want to be in the class at all. He's always trying new things, but this cross-pollination of students means every innovation has to satisfy two standards:1. It has to make people fitter;2. It has to make people happier.Sound familiar?Ray coined the phrase we repeat at Catalyst often: "Exercise until you're happy." It's the base of the hierarchy he teaches students. He also teaches research skepticism: how to read and rank the value of "research." Imagine a generation of people who believe what they read on Facebook: that's what's coming, except for the students in Ray's classes.I introduce this episode with the question, "Are we measuring 2016 results with 2001 technology?" CrossFit coaches are the champions of objectively-measurable fitness, and exercisers become addicted to having a "score." But other gym chains, like Orange Theory, are beginning to nibble at our lunch: giant scoreboards focusing on one correlate of fitness draw huge crowds. We can be defensive, or we can do better.This episode is the beginning of that conversation: how do we leverage tech to enhance fitness? Will measurement and feedback help us reach higher levels...or is it only useful to get clients in the gym more often?In "Coach's Confessional," I talk about the one of the (very few) mistakes I HAVEN'T made myself, but see all too often in struggling gyms: the "lifetime membership." It's a monkey's paw, and I'll explain why.My next seminar is April 16 in Charlotte, NC. Get signed up!
