Body mass index (BMI) is a number obtained by dividing the kilograms of weight by the square of the meters of height. It is a widely used international standard to measure the degree of obesity and health. You weigh 52kg. Suppose your height is 160cm. Body mass index = 52/ 1.6 2 = 20.3 125, and your body fat rate = [1.2x20.3125+0.23x16-5.

PSS: female body fat formula;

Parameter a = waist circumference × 0.74

Parameter b = weight × 0.082+34.89.

Body fat weight = a-b

Body fat percentage (body fat percentage) = (total body fat weight/body weight) × 100%

This is a general fitness calculation method. Compare with yourself.
