Reliable Blood Pressure cuff?

I am in a weight loss program through my insurance company and one of the requirements is to be evaluated every three months by walking on a treadmill for two minutes having your blood pressure taking while still walking, then at four minutes while walking, at six minutes when you have stopped and then again at ten minutes when you have rested for four minutes. My question is, does anyone know of a reliable blood pressure cuff that I can get to take BP while in motion that will still be accurate so I can track these numbers on my own? Both of my parents have high blood pressure and heart problems and I want to prevent me from having that same fate if possible. Thank you for your help.
