The chart below shows four friends' target heart rate zones. During their last spin class, each person averaged 170 beats per mi
nute. Based on this information, who worked at the highest intensity level? Name Target Heart Rate Zone Janna 146bpm—188bpm Shania 145bpm—188bpm Paige 140bpm—182bpm Mimi 140bpm—185bpm
Paige exhibited the highest intensity level during the class.
You might think I’m mistaken due to Paige having the lowest target heart rate among them, but paying close attention to the question reveals the truth. The target heart rate zone (THRZ) indicates the optimal limits you should not surpass or fall below. A person’s heart rate directly correlates with their exercise intensity. According to her THRZ, Paige's maximum heart rate is 182. On closer inspection, you can see that 182 is the closest to 170, which makes Paige the correct choice.
