Exercise helps, but I had to go to a strict monitoring of my diet to get sodium intake below 1500 mg to get to a safe BP. (My high BP is definitely linked to sodium intake, and I have years of daily logs to back that up. The R squared coefficient of determination is about 0.85)
From last week's logs, the average BP and pulse:
weekly morning 102/70 49
weekly evening 103/69 52
I do 5 one hour sessions of cardio training a week. Age 61
That is really good to hear success stories like this. I hope to keep my BP in control with exercise and diet as long as I can.
