Question

question 1 of 5
why is it necessary to frequently update a workout program?
a. a workout program must gradually be made more challenging, so
the body can continue to improve as it adjusts.
b. a workout program must be updated every 4 - 6 weeks in order to
address different muscle groups.
c. maintaining the same workout program will cause boredom,
making the possibility of quitting much higher.
d. a workout program must be updated every 4 - 6 weeks in order to
address different fitness components, such as flexibility, cardio
endurance, and resistance training.

Explanation:

The principle of progressive overload in fitness means the body adapts to stress. As it gets used to a workout, increasing challenge (like more weight, reps, or intensity) is needed for continued improvement. Option B is incorrect as workouts can target multiple muscle groups without a strict 4 - 6 week update tied only to that. Option C about boredom is a secondary factor compared to physical adaptation. Option D's 4 - 6 week update tied to fitness components is not the main reason; progressive overload (as in A) is more fundamental.

Answer:

A. A workout program must gradually be made more challenging, so the body can continue to improve as it adjusts.
