  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) ) = .03787 x 703 = 26.62 % body Fat • Or the cheater’s way • Go to http://www.nhlbisupport.com/bmi/

  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 = 655 + ( 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 • http://www.bmi-calculator.net/bmr-calculator/

  10. Body Composition • Ideal Body Weight • Overweight Versus Obese • Not the same thing • Height and Weight do not account for the amount of muscle
