While you shouldn't shrug off the change, there's also no need to panic. "Obviously, nothing happened overnight inside a woman's body or to her health with the release of the guidelines," says Dr. Naomi Fisher, director of hypertension service and hypertension innovation at the Brigham and Women's Hospital Division of Endocrinology, Diabetes, and Hypertension, and associate professor of medicine at Harvard Medical School.
Once you know your resting heart rate, you can then determine your target training heart rate. Target heart rates let you measure your initial fitness level and monitor your progress in a fitness program. You do this by measuring your pulse periodically as you exercise and staying within 50 to 85 percent of your maximum heart rate. This range is called your target heart rate.
Exercise can also lead to lower blood pressure. Although performing moderate to vigorous exercise leads to higher blood pressure during activity, it is lowered afterwards. A wealth of studies indicate that getting 150 minutes per week of exercise—whether walking, cycling, gardening, dancing, or weights—can lead to significant drops in blood pressure over time. Try to exercise every day, but even three or four times per week can bring on big improvements.
