Depending on the starting out point and the initial Body Weight / Mass Ratio of the person involved it is probably not inconceivable that a 5 mmHg drop in blood pressure can be achieved through regular exercise. Add to that a good diet and you are really starting to make some headway.

The level of exercise to achieve these benefits is not excessive – a good walk or swim three times a week is enough to show results.

Exercise has a definite positive effect on the cardiovascular system and the attendant risks. Those who exercise regularly and are fit (whether they actually suffer from High Blood Pressure or Hypertension) have only a fraction of the risk (typically between 50 to 20 percent) of those who do not take regular exercise or are unfit.
