BMI is a measurement of body fat based on height and weight that applies to both men and women between the ages of 18 and 65 years.
BMI = ( Weight in Pounds / ( Height in inches x Height in inches ) ) x 703
BMI = ( Weight in Kilograms / ( Height in Meters x Height in Meters ) )

Heart Rate
Maximum Heart Rate (HR) is about 220 minus your age.
The American Heart Association recommends that you do exercise that increases your heart rate to between 50 and 75% of your maximum heart rate (your maximum heart rate is 220 beats per minute, minus your age). They recommend getting at least 30 minutes of exercise on most days of the week (AHA, 2006).
Blood Pressure
Blood Pressure is the force of the blood against the walls of arteries. It includes two measurements:
Systolic pressure (top number): The pressure as the heart beats and forces blood into the arteries
Diastolic pressure (bottom number): The pressure as the heart relaxes between beats
Average value for young people: 120/80 mmHg
Average value for old people: 140/90 mmHg
Healthy blood vessels dilate to allow more blood to flow through more easily. When you exercise, your heart speeds up so the blood can reach your muscles. It may be possible for your heart rate to double safely, while your blood pressure may respond by only increasing a modest amount. When you stop exercising, your pulse does not immediately return to normal; it gradually returns to its resting level. The greater your fitness level, the sooner your pulse rate will return to normal.
