Your muscles use three energy systems to power movement: the phosphagen system, glycolytic system, and aerobic system. This video breaks down how ATP is produced during exercise, when each system dominates, and why the common belief about lactic acid causing fatigue is wrong.
You'll learn how phosphocreatine powers explosive efforts for 10-15 seconds, how glycolysis sustains high-intensity work for up to 2 minutes, and how aerobic metabolism fuels endurance activities. We'll cover the science behind ATP production, the real cause of muscle fatigue (hint: it's inorganic phosphate, not lactate), and how understanding energy systems can improve your training.
