Know Your Weight

Step Right Up!

Body Mass Index
Body Mass Index (BMI) is a number calculated from a person's weight and height to determine the overall fitness of an individual. BMI does not measure body fat directly, but is used as a diagnostic tool to identify potential obesity problems.

Body Composition Index
The basic rule of body composition measurement is that muscle sinks and fat floats. Tarita takes a dunk in the Fitness Wave mobile hydrostatic body fat testing lab and gets her body composition measured.

Hormone Levels
A woman's hormone levels can affect everything from her mood, skin and hair to her menstruation cycle and fertility. When hormone levels are off, the body suffers. OB/GYN Dr. Lisa Masterson explains medical options to remedy female hormone disorders.

Sports medicine orthopedist Dr. Vonda Wright says that when it comes to fat, it's all about location, location, location. Fat is metabolically active, so it matters where we accumulate it. 

How Your Body Shape Affects Your Health

Bone Density
Bones are filled with minerals that supply our bodies with energy. Bones will replenish themselves up to 10 percent every year, and one way to make them stronger is to engage in weight-bearing activity.

How to Keep Your Bones Healthy

Cholesterol is a fat-like substance found in the bloodstream and is an important and necessary part of cellular function in the body. There are two types of cholesterol: low density lipoproteins (LDLs) and high-density lipoproteins (HDLs).
