BMI stands for body mass index and is a measure of height to weight. It doesn’t take into consideration body composition, age or gender. Therefore is not the most reliable measure for obesity. It is however, and good rule of thumb tool when trying to determine your health risks associated with weight.

A very fit person with higher amount of muscle mass may have a high BMI even though they are healthy a fit.

BMI Categories:

• Underweight = <18.5
• Normal weight = 18.5–24.9
• Overweight = 25–29.9
• Obesity = BMI of 30 or greater

1) To calculate your BMI measure your weight in pounds and height in inches. Then multiply the answer by 703

• [Weight / (height x height)] x 703 = BMI
Yes.  There are some individuals, particularly those who perform a lot of strength training, that are very muscular.  This would, of course, cause them to weigh more.  By weighing more, the BMI calculation might classify them as overweight or obese.  However, having large amounts of muscle mass relative to fat mass is healthy and fine.
