Anaerobic Glycolysis

Anaerobic glycolysis is a process your body uses to produce energy without oxygen, mainly during short bursts of intense exercise, like sprinting or lifting weights. When oxygen is scarce, glucose—the sugar in your blood—is broken down into energy. This generates a byproduct called lactate, which can lead to muscle fatigue. While anaerobic glycolysis is less efficient than aerobic processes (which use oxygen), it allows for quick energy production, enabling you to perform high-intensity activities for a short duration before needing to catch your breath.
