Which client is not meeting minimum guidelines for cardiovascular exercise according to the American College of Sports Medicine/CDC?

The correct answer identifies Sara as not meeting the minimum guidelines for cardiovascular exercise according to the American College of Sports Medicine and CDC recommendations. These guidelines suggest that adults should engage in at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity aerobic activity each week.

While Sara incorporates walking into her daily routine, the total amount of walking she does may not suffice to meet these recommendations, especially if her walks to and from work are not of sufficient intensity or duration to count toward those weekly minutes. Depending on her walking pace and frequency, it is possible that she is not accumulating the recommended amount of cardiovascular exercise.

In contrast, Maylin's routine of running for 45 minutes four times a week is well above the minimum guideline, Celissa's stair climbing adds up to a significant amount of activity throughout the week, and Donald's biking and dance class ensure he reaches or exceeds the cardiovascular activity recommendations weekly. Each of these clients demonstrates a consistent and sufficient commitment to aerobic exercise, while Sara's routine does not guarantee adherence to the minimum guidelines.
