What is the principle of Progressive Overload?

• A. Gradually increase training intensity and/or volume
• B. Maintain constant training intensity
• C. Increase rest between sessions only
• D. Circulate workouts randomly

Answer: (A)

Progressive overload means steadily increasing the demands placed on the body so it has to adapt. The way to apply this is to gradually raise the training stimulus over time, such as lifting heavier weights, doing more repetitions or sets, swimming longer distances, or working at a faster pace. By routinely making the workout harder, the muscles, energy systems, and nervous system adapt to handle that higher load.

Keeping the same intensity over time won’t spark continued improvements, because the body adapts to the current demand and then stalls. Merely increasing rest between sessions reduces the training stimulus and doesn’t push adaptation. Circulating workouts randomly can fail to provide a clear, progressive load, so gains become inconsistent.
