Body Fat Analyzer Electronic BIA Meter Incredibly Accurate Built-In Clock & Alarm + Fast & Easy Results Batteries Included

Body Mass Index, or BMI, is not a highly accurate way to gauge one's health, because it does not account for muscle mass or variation in body types.

A better way to measure is to use BIA, or Bio electrical Impedance Analysis. This Body Fat Analyzer sends an undetectable electrical current through your skin to make a calculation of total body fat percentage. Although your level of hydration can affect the result, BIA is recognized as an accurate way to measure body fat percentage. It is recommended to measure twice a month, in the evening at approximately the same time of day.
The meter has a highly portable design and is easy to use. Take it with you anywhere you travel!

A pedometer senses your body motion and counts your footsteps. This count is converted into distance by knowing the length of your usual stride. Wearing a pedometer and recording your daily steps and distance is a great motivating tool. You can wear a pedometer all day, every day and record total steps. Or you can wear it just when you go out for a walking workout.

Multi-function Pedometers

All pedometers count steps, although they may use different methods to do so. These include (in general order of accuracy): piezo-electric accelerometers, a coiled spring mechanism, and a hairspring mechanism. Beyond showing the step total and/or calculating the distance, features abound. The top features are: Calorie estimates, clocks, timers, stopwatches and speed estimators, 7-day memory, pulse rate readers.
