Post-Workout Insulin Spike

Meaning

A Post-Workout Insulin Spike refers to the rapid and significant surge in the circulating concentration of the hormone insulin immediately following an intense or prolonged exercise session, typically induced by the ingestion of high-glycemic index carbohydrates and fast-acting proteins. This strategic elevation is deliberately sought in performance and hypertrophy protocols to leverage insulin’s powerful anabolic and anti-catabolic properties. The spike serves as a metabolic “on-switch” for the critical recovery and repair processes.
