please select the best answer from the choices provided.

○ a
○ b
○ c
○ d

Explanation:

The principle of overload in exercise (a concept in areas like Health/Fitness, related to 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 increase 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 over time. Option D is about varying exercises (principle of variation, not overload).

Answer:

A. gradually increase the difficulty of a workout
