WHY PERFORMANCE IS ABOUT TRANSITIONS, NOT INTENSITY
Most people think performance improves by pushing harder. More intensity, more volume, more effort, more stimulation. That belief makes sense because intensity is visible. You can see heavy weights, fast running, deep breathing, sweat, and fatigue. What you cannot see is what actually determines whether the body adapts or breaks down. That hidden factor is how well the body handles transitions. Biology does not reward force. It rewards coordination. At every level of the body, from a single cell to the entire nervous system, health and performance depend on how smoothly systems shift from one state to another. These shifts include rest to effort, effort to recovery, fed to fasted, stress to calm, inflammation to healing, and sleep to wakefulness. The quality of these transitions determines whether the system becomes stronger or weaker over time. A transition in biology is any moment when demand changes faster than structure can adapt. When exercise begins, muscles suddenly require more energy. When exercise stops, energy demand suddenly drops. When food is eaten, nutrients flood the bloodstream. When fasting occurs, energy must be mobilized internally. When stress hormones rise, immune and metabolic priorities shift. These changes are not steady states. They are moments of adjustment, and they are where the system is most vulnerable. Most people misunderstand how energy works in the body. Energy is not something you simply have or run out of. Energy is controlled flow. At the cellular level, this flow is managed by mitochondria. Mitochondria are often called powerhouses, but a better way to understand them is as traffic controllers. Their job is not just to make energy, but to regulate how electrons move through a tightly controlled system. Electrons enter mitochondria from the breakdown of food and stored fuels. These electrons move through a series of protein complexes called the electron transport chain. As electrons move through this chain, energy is released in a controlled way to produce ATP, the molecule used to perform work. ATP is not the goal. It is the result of proper electron flow. When electron flow is smooth, energy production is clean and signaling is preserved. When electron flow becomes congested, problems arise.
