Ever feel overwhelmed by energy systems, wondering why your clients need to know about ATP or glycolysis? Dr. Jacob Goodin cuts through the complexity to reveal how bioenergetics knowledge transforms your coaching from guesswork to precision-guided results.
The conversation begins with a clear breakdown of our three energy systems: the phosphagen system (lightning-fast but brief), glycolytic system (moderate speed and capacity), and oxidative system (slow but virtually unlimited). Dr. Goodin explains how these systems work in concert—not isolation—to fuel everything from explosive jumps to marathon runs. What makes this discussion particularly valuable is how he translates complex physiology into practical coaching insights.
Perhaps most eye-opening is the myth-busting around the "fat burning zone." While lower-intensity exercise does use a higher percentage of fat for fuel, Goodin clarifies why this approach isn't optimal for fat loss: "The most time efficient way to lose fat is to build muscle and do higher intensity exercise." This single insight could transform how you approach conditioning for weight management clients.
The podcast delivers golden nuggets about programming structure, explaining why putting cardio at the beginning of a workout compromises force production and hypertrophy gains. We learn why power and skill work should come first, strength second, accessory movements third, and conditioning last—a sequence backed by physiology rather than tradition.
What separates this conversation from typical fitness content is its balance between science and application. Goodin doesn't just explain what happens in the Krebs cycle; he shows how understanding these processes helps you design better work-to-rest ratios, choose appropriate modalities for different clients, and create training sessions that satisfy clients while delivering results.
