If you lose 5 pounds of fat and gain 5 pounds of muscle a scale would show you made no progress at all. Since a traditional scale only measures body weight the results can be deceiving. With the help of the Inbody330 we can make sure you are losing body fat while maintaining or gaining lean body tissue (which has a direct reflection on your metabolism.) The Inbody330 prints out a detailed report of all the information it collects charting the information into an easy to follow graph format. It is recommended a person get an analysis every 2 to four weeks to track results. Unlike some units that only measure your upper body by holding on to the unit with the hands the Inbody330 measures the upper body, lower body, and trunk simultaneously to insure the most accurate body fat measurement available.
