Question

a. 15 minutes to warm up, 15 minutes of aerobic activity, 15 minutes to cool down

b. 5 minutes to warm up, 25 minutes of aerobic activity, 0 minutes to cool down

c. 0 minutes to warm up, 15 minutes of aerobic activity, and 15 minutes to cool down

d. 5 minutes to warm up, 20 minutes of aerobic activity, 5 minutes to cool down

Explanation:

A proper aerobic exercise plan should include a warm - up (to prepare the body), an aerobic activity period (of sufficient length for benefits), and a cool - down (to gradually return the body to rest).

• Option A: The aerobic activity time (15 minutes) is relatively short for a good aerobic workout.
• Option B: No cool - down is not ideal as it helps in reducing muscle soreness and preventing blood pooling.
• Option C: No warm - up can increase the risk of injury.
• Option D: A 5 - minute warm - up, 20 - minute aerobic activity (a reasonable duration for aerobic benefits), and 5 - minute cool - down is a well - balanced plan.

Answer:

D. 5 minutes to warm up, 20 minutes of aerobic activity, 5 minutes to cool down
