number of things. if you've had a physical exam, as well as a treadmill test, or
filled out a health background questionnaire, the information from these is
referenced. Medical health, current fitness level, body weight/body composition,
and other related data is used to prescribe the training heart rate, duration,
frequency and total weekly kilocalories expenditure. The exercise prescription
maximizes the benefits in as short a period of time as possible, while
minimizing health risks.
