Runners are great at tracking pace, heart rate, mileage, and exactly which gel destroyed their stomach at mile 30.But how well do we actually understand the body doing all that work?

In this solo episode, Nick breaks down four systems every runner should understand: how your muscles work together while running, the difference between sweat rate and sodium loss, why race fuel can cause gastrointestinal problems, and the minimum amount of strength training runners actually need.

We cover why your glutes probably aren’t “asleep,” why a bathroom-scale sweat test only tells you part of the story, which ingredients may contribute to stomach problems, and how to build a simple two-day strength routine without living in the gym.This isn’t about finding one perfect formula. It’s about understanding your body well enough to test, adjust, and stop guessing when the miles get ugly.Topics include:
  • The muscles responsible for efficient running
  • Glute and core strength versus “activation”
  • Sweat rate versus sweat-sodium concentration
  • How legitimate sweat testing works
  • Why sodium doesn’t guarantee cramp prevention
  • Common causes of gastrointestinal distress
  • Glucose, fructose, sugar alcohols, fiber, and caffeine
  • How to train your gut for race-day fueling
  • A two-day strength plan for runners
  • Calf, soleus, hip, and core exercises
  • How to schedule strength work around running
