You might want to ask your doctor...and consider how high your blood pressure is and what other risks you may have for heart disease
, history of heart disease, etc...
but 191 is below 200 which is usually where you want it to be...
You also need to look at the LDL and HDL
bad and good cholesterol.. and triglycerides. Exercise helps the good cholesterol
You may need to have your cholesterol checked more often than every five years if one or more of these situations applies to you:
Your total cholesterol
is 200 mg/dL or more.
You are a man over age 45 or a woman over age 50.
Your HDL (good) cholesterol is less than 40 mg/dL.
You have other risk factors for heart disease and stroke
