wrap the blood pressure cuff aruond your upper arm
take the stethoscope and lightly press it's bell over the brachial artery just below the cuffs edge
rapidly inflate the cuff up to 180mmHg then release the air at a moderate rate (3mm/sec)

Benefits:
Size of the heart increases
power of the heart muscle increases
keeps the artery walls flexible
