What describes the principle of progressive overload in a training plan?

• A. Gradually increasing stress (load, volume, or frequency) with small weekly increments and deload weeks
• B. Starting with maximal loads and increasing only when pain occurs
• C. Never changing the training stimulus to prevent injury
• D. Increasing only the number of workouts without changing intensity or duration

Answer: (C)

Progressive overload means continually challenging the body by increasing training demands over time to provoke adaptations. The best description is gradually raising stress in the plan—by adding weight (load), increasing the number of repetitions or sets (volume), or training more often (frequency)—and including planned deload weeks to allow recovery and adaptation. This approach builds strength, endurance, or size while managing fatigue and injury risk.

Starting with maximal loads and waiting for pain to dictate increases is reactive and unsafe, so it doesn’t describe progressive overload. Never changing the stimulus prevents improvements entirely. Increasing only the number of workouts without raising effort, duration, or load also doesn’t guarantee a true progressive stimulus, since the body needs higher demands to adapt.
