Demystify energy systems and learn how they actually function, interact, and adapt—so you can train them with purpose.
Meet the body’s three energy systems—phosphagen, glycolytic, and oxidative—and learn how each produces ATP to fuel movement. This lesson breaks down their roles, capacities, and how they contribute across different intensities and durations of exercise.
6m
Learn how the energy systems work together in real-world movement. This lesson explores their coordinated roles across intensities, durations, and intermittent sports—revealing why no activity relies on just one system in isolation.
6m
This lesson explores the physiological and mechanical factors that influence energy system function. You’ll learn which adaptations are trainable, how they differ in responsiveness, and why both central and peripheral systems shape energy system performance.
6m
This lesson breaks down how to design effective energy systems training. You’ll learn key principles, formats, and adaptations—plus how to match training variables to outcomes without oversimplifying or isolating energy systems.
