With which training principle is the exhaustion stage connected?

• A. Progressive overload
• B. Specificity
• C. Overtraining
• D. Reversibility

Answer: (C)

Exhaustion is the point at which the body's response to ongoing training stress can no longer cope, so adaptive processes fail and performance begins to decline. This directly fits with overtraining, the state where excessive workload without adequate recovery leads to persistent fatigue, performance drops, and other negative signs. It’s the maladaptive end of the stress–recovery cycle, not the intended outcome of progressively increasing load, nor the way the body adapts to a specific task, nor the loss of adaptations from stopping training. So the exhaustion stage is tied to overtraining.
