LifeSpan TR2250-HRC manual Female Range Male Range Age Excellent Good Poor

Body Composition – the TR2250 comes with 3 different body composition measures. These are Body Fat Percentage, Body Mass Index, and Basal Metabolic Rate. None of these measures are perfect and all of them should be used only as a relative gauge. These three measures are briefly described below:

•Body Fat Percentage is calculated using a technique called Bioelectrical Impedance Analysis (BIA). This is a simple and easy way to determine body fat by sending a signal from one hand to another while the users hands are placed on the heart rate sensors. The faster the signal travels the higher the muscle density. The results are based on the fact that muscle tissue conducts electricity faster than fat because muscle is about 70% water and fat contains almost no water.

•Body Mass Index (BMI) is a scientific measure that uses a ratio of height and weight. It is a general measure of health risk, but does not take into account lean body mass. As a result, a healthy muscular individual with very low body fat can be classified as over weight. The following are general ranges of BMI measurements:

Below 20	Lean – if you are not an athlete you should consider gaining
	weight through good diet and exercise
Between 20 and 22	Ideal – indicates a healthy amount of body fat and the lowest
	incidence of serious illness
Between 35 and 30	Slightly Overweight – increased risk for a variety of illnesses.
	You should find ways to reduce your weight through diet
	and exercise.
Over 30	Overweight – indicates an unhealthy condition with a higher
	risk of heart disease, diabetes, high blood pressure, gall bladder
	disease and some cancers. You should focus on losing weight
	by changing your diet and increasing levels of exercise.

•Basal Metabolic Rate is the number of calories used by the body when it’s at rest. It is calculated using age, sex, height, and weight. The BMR number shown on the display is a three digit number. You will need to add a “0” to the end of the number to get your actual BMR.
