Health aware

Buck 50 and Bre 18 started a neighborhood walking program three weeks ago. It stemmed from the fact that Bre gained 12 unwanted pounds during her senior year of high school. Buck remains involved in community affairs but spends quality time caring for his physical health on a daily basis. This walking program has already sparked tremendous interest. Bre’s weight gain has gotten her attention since starting college. Family and friends have commented about her new look. Aside from this look, she has experienced a reduction in her energy level. Bre’s resting heart rate is 84 beats per minute. Buck looks closer to 34-35 years old. He works hard supporting his family, tirelessly. Buck’s resting heart rate measured at 72. Please answer the following questions: 1. What would be Buck’s target heart rate workout range? 2. What would be Bre’s target heart rate workout range? 3. True or False: Buck must always workout with greater intensity than the much younger Bre to maintain a physical edge.
