BMI Calculator
Body Mass Index assesses weight in relation to height.
How They Work
BMI (Body Mass Index): A simple screening tool that estimates body fat based on your height and weight. While useful for general populations, it doesn't account for muscle mass.
BMR (Basal Metabolic Rate): The number of calories your body needs to accomplish its most basic (basal) life-sustaining functions.
TDEE (Total Daily Energy Expenditure): An estimation of how many calories you burn per day when exercise is taken into account. It is calculated by first figuring out your Basal Metabolic Rate, then multiplying that value by an activity multiplier.
Target Heart Rate: Helps you identify the right exercise intensity for your goals. Using your age (and optionally your resting heart rate), we can determine the heart rate zones that maximize fat burn or cardiovascular endurance.
