8. Body Composition
The Body Mass Index (BMI) - is a measurement tool that compares your height to your weight and gives you an indication of whether you are overweight, underweight or at a healthy weight for your height.
BMI = (Weight in Pounds / Height in Inches ²) Multiplied by 703
Ex. (160 / (65” x 65”= 4225) ) = x 703 = % body Fat

9. Body Composition Basal Metabolic Rate Calculation
This under the assumption that you expended minimal calories. Basically that you stayed in bed all day
Women: BMR = ( 4.35 x weight in pounds ) + ( 4.7 x height in inches ) - ( 4.7 x age in years )
Men: BMR = 66 + ( 6.23 x weight in pounds ) + ( 12.7 x height in inches ) - ( 6.8 x age in year )
Or the Cheater’s way
