I had the same problem too, "borderline hypertension." A regular exercise program, 3 times 1 hr per week brought me back down to 80/130. Before that I was at 90/140, with spikes up to 100/160.
Also, regular exercise has the added benefits for me such as:
1. Elimination of aches and pains
2. Much more energy
3. Improved self-image and confidence.
Just my antedotal (sp?) observations. As always, follow the advice of your health care professional!
Good luck!
