BMI : Body Mass Index

The Body Mass Index (BMI) is a quick way to assess your body size simply with your weight and height, regardless of your gender. Quickly calculate your BMI and find out which category you fall into. The Body Mass Index (BMI) is the only index validated by the World Health Organization to assess an individual's build and therefore possible health risks. The BMI allows you to determine whether you are underweight, overweight or obese, for example.

BFP : Body Fat Percentage

The body fat percentage (BFP) of a human or other living being is the total mass of fat divided by total body mass, multiplied by 100; body fat includes essential body fat and storage body fat. Essential is necessary to maintain life and reproductive functions. The percentage of essential body fat for women is greater than that for men, due to the demands of childbearing and other hormonal functions. Storage body fat consists of fat accumulation in adipose tissue, part of which protects internal organs in the chest and abdomen. A number of methods are available for determining body fat percentage, such as measurement with calipers or through the use of bioelectrical impedance analysis.

LBM : Lean Body Mass

Lean mass represents a complex compartment. It is the most physiologically important compartment. It makes up 70-90% of body weight, and is made up of bones, muscles, organs, skin, and body fluids. The basic metabolism of the human being depends mainly on the lean mass.

For strength athletes, LBM replaces Body Mass Index (BMI), which is irrelevant for muscular people. BMI is more suitable for people with little muscle and is only a first comparison. The Lean Mass Index, on the other hand, is better suited to athletes who train regularly and provides a much more relevant analysis of body condition.

BMR : Basal Metabolic Rate

The BMR, or basal metabolism, corresponds to the "incompressible" energy needs of the body, that is to say the minimum daily energy expenditure allowing the body to survive; at rest, the body consumes energy to keep its functions active (heart, brain, breathing, digestion, maintaining body temperature), via biochemical reactions. It is expressed on the basis of a day, so in joules or calories per day.

Basal metabolism depends on height, weight, age, sex and thyroid activity. The outside temperature and climatic conditions also have a significant influence. Basal metabolism decreases with age, by 2-3% per decade after adulthood. Children on the other hand have a basal metabolism twice as high as that of adults.

IW : Ideal Weight

The ideal weight does not exist! Yes, if there are indeed several scales allowing it to be evaluated according to various criteria, the most important thing is obviously to be good about yourself ... Apart from the body mass index (BMI), the only one validated by the Organization World Health Organization (WHO), there are other more personalized indices that take other variables into account to calculate your ideal weight.

It exist different formulas for calculating the ideal weight, we used the Lorentz formula.

However, these results should be taken with a grain of salt and viewed as mere indicators. They are not a substitute for medical advice and whatever the result, the most important thing is to feel in good shape! Provided that this does not present any health risks. Indeed, in a situation of extreme thinness, overweight and obesity, the consequences for health are real, which can strongly impact the quality of life but also longevity.
