During the late day my pressure is normally about 115 over 64 or so. In the morning my pressure is usually about 95 over 55 and after morning carido exercise 105 over 55. I am a 54 year old male, but I am a little worried about the low diastolic number as I read this could be indicative of arteriosclerosis. I did have an echo-stress test a few months ago and was told I had the fitness level of a college athlete. Normally work out on a elliptical 60 minutes in the morning at 80 - 85% of my theoretical target heart range, except twice a week when a do very high intensity intervals for twenty minutes. I never get dizzy, short of breath during exercise or any other time. So is the low diastolic pressure something to worry about as I have read under 60 is bad.
