Explanation:

The principle of overload in exercise (related to fitness, a subfield of Natural Science - Medicine and Health) states that to improve fitness, you must gradually increase the stress (difficulty) on the body. Option A matches this: gradually increasing workout difficulty. Option B is incorrect (decreasing difficulty doesn't follow overload). Option C is about engaging in challenging exercise but not the gradual increase. Option D is about variation (principle of specificity/variation, not overload).

Answer:

A. gradually increase the difficulty of a workout
