Use these helpful tools to calculate your Body Mass Index (BMI), Basal Metabolic Rate (BMR), Active Metabolic Rate (AMR) and many other useful items to help supplement your exercise routine and facilitate your weight loss goals.

The Body Mass Index (BMI) is a formula designed to indicate a body’s mass and is used to classify weight categories. Many physicians and nutritionists use BMI as an accurate snap-shot into a person’s health; however other factors should be calculated as well.

Underweight	<18.5
Normal	18.5-24
Overweight	25-29
Obese	30-40

BMI

The Basal Metabolic Rate (BMR) is a formula used to calculate the amount of energy used while at rest. It tells you how many calories you burn a day while not doing any sort of strenuous activity. Basically this tells you how many calories your body burns to simply breathe, eat and do other non-strenuous activities. These are the calories that you burn while "at rest."

The Active Metabolic Rate (AMR) calculates the calories you burn each day to support your activity level. After you calculate your AMR, add this to your BMR for the total number of calories that you need to consume a day to maintain your current weight. If you eat less then you are burning, you will start to lose weight. If you eat more than you are burning, you will gain weight.

Calories you eat = Calories you burn = Maintain your weight
Calories you eat > Calories you burn = Gain weight
Calories you eat < Calories you burn = Lose weight

BMR & AMR

Caloric Intake breakdown tells how many calories you should consume through carbohydrates, proteins and fats. Enter the number of calories that you would like to consume per day based on what you have just calculated with your BMR and AMR.

Target Heart Rate will calculate your target heart rate for optimal fat burning or cardiovascular training.

Optimal % for Fat Burning is between 55%-70% of your maximum heart rate.
Optimal % for Cardiovascular training is between 70%-85% of your maximum heart rate.

Enter your age and the appropriate percentage depending on your exercise goals. You will then see your Target heart rate and the recommended target range of beats per minute.

Enter your age:
