A 30-year-old man is aiming to do moderate aerobic exercise. After 10 minutes, he measures his heart rate as 120 bpm. He determines that his heart rate is sufficient to achieve his goals. Is he correct?

Yes, but he should introduce intermittent high-intensity exercise until his heart rate equals 100. Yes, but he should introduce intermittent high-intensity exercise until his heart rate equals 100. , ,

No, he should exert more effort and raise his heart rate above 120.No, he should exert more effort and raise his heart rate above 120. , ,

No, he should slow down as the heart rate should fall between 80 and 100 bpm.No, he should slow down as the heart rate should fall between 80 and 100 bpm. , ,

Yes, he should maintain the same pace because 120 is his target heart rate.

After quick research I learned that your target hear rate should be between 64% and 76% of your maximum heart rate for moderate-intensive physical activity.

To find your max heart rate for your age, subtract your age from 220. The 64% and 76% levels would be:

4% level: 170 x 0.64 = 109 bpm, and

76% level: 170 x 0.76 = 129 bpm

During workout.
