Hi Tammy, Welcome to MyDietExercise! Optimal blood pressure is 120/80 as you can see blood pressure readings include two numbers: systolic blood pressure and diastolic blood pressure.   The top number (120) is the systolic pressure, which is the pressure within the arteries while the heart is pumping, whereas the bottom number (80) is the diastolic pressure, a measure of pressure within the arteries while the heart is resting and refilling with blood.   To find your range, see the helpful blood pressure chart below.  That also includes suggested normal ranges by age http://www.disabled-world.com/artman/publish/bloodpressurechart.shtml   Health and Happiness Kenn Kihiu http://www.danceXfitness.com
