Explanation:

The principle of overload in fitness states that to improve physical fitness, the body must be exposed to increased stress or load over time. This is achieved by gradually increasing the difficulty of a workout. Decreasing difficulty goes against the principle. Just engaging in challenging exercise once is not the essence of overload, and varying exercises is related to variety principle rather than overload specifically.
