Quizplus · Accepted Answer

According to CDC guidelines, for a vigorous-intensity workout, a person's heart rate should be between 70% to 85% of their maximum heart rate. The formula to calculate maximum heart rate is 220 minus age. In Ronald's case, his maximum heart rate would be 180 (220-40=180). To achieve a vigorous-intensity workout, his heart rate should be between 126 bpm (70% of 180) and 153 bpm (85% of 180). Therefore, the best choice is D - 153 bpm.
