After exercising, both Sandra and <span>Marissa had a heart rate of 144 bpm.
Now, we will decrease this heart rate by 20 for each one as mentioned and compare to the THR:
1- Sandra:
Heart rate after decreasing 20 bpm = 144 - 20 = 124 bpm
Her target heart rate zone is </span><span>135 bpm—172 bpm
Therefore, Sandra will not be in her THR zone
2- </span><span>Marissa:
Heart rate after decreasing 20 bpm = 144 - 20 = 124 bpm
Her target heart rate zone is </span><span>143 bpm—176 bpm
Therefore, Marissa will not be in her THR zone</span>
