Dominique's target heart rate zone is 150bpm—183bpm. josh's target heart rate zone is 135bpm—175bpm. when they stop running and immediately take their pulse, both count their heart rate at 165bpm. if they decrease their heart rates by 20bpm, who will be in his or her thr zone?

It will be Josh who gets his target THR. His range is within 135 bpm—175 bpm while the actual heart rate was 165 bpm, deducting it with 20 bpm results to 145 bpm - falling to the 135 bpm—175 bpm THR range. Although doing the same method as Josh's results to 165 bpm for Dominique, it doesn't fall to his 150 bpm—183 bpm THR range.
