Explanation:

Question 4

• "To induce fatigue" is incorrect as warm - up should prepare the body, not tire it.
• "To decrease blood flow to the muscles" is wrong; warm - up aims to increase blood flow.
• "To promote relaxation" is not the main goal of warm - up intensity increase.
• Gradually increasing warm - up intensity helps the body (muscles, cardiovascular system) get ready for the workout, so "To prepare the body for the upcoming workout" is correct.

• "Increase heart rate" is for warm - up, not cool - down.
• Low - intensity aerobic exercise during cool - down helps move blood from extremities back to the heart, preventing blood pooling.
• "Improve flexibility" and "Enhance joint mobility" are more related to stretching in cool - down, not aerobic exercise.

Answer:

D. To prepare the body for the upcoming workout (assuming the options are labeled A - D with A: To induce fatigue, B: To decrease blood flow to the muscles, C: To promote relaxation, D: To prepare the body for the upcoming workout)
