The chart below shows four friends' target heart rate zones. during their last spin class, each person averaged 172 beats per minute. based on this information, who worked at the highest intensity level? name target heart rate zone jeff 135bpm—175bpm mike 145bpm—188bpm ty 140bpm—180bpm liam 140bpm—183bpm

The correct answer would be Jeff

Explanation:

Jeff's high end of his target heart rate zone is lower than everyone else. This means that he has to work the hardest to get his heart rate to that point. Since he had an average heart rate of 172 and the limit of his target heart rate zone is 175, he was inherently working the hardest.

i believe the answer would be negative peer pressure
