Getting the low-down on your body fat percentages can involve a scale, calipers, calculator, spreadsheet, and lots of math. Enter the Tanita Ironman Segmental and Full Body Composition monitor. This torture device comes with retractable hand-grip electrodes that measure each body quadrant's water, muscle mass, bone mass, BMR, visceral fat, metabolic age, and physique rating. Engadget Fitness Club (EFC) public service note: keep in mind that electrodes of this sort can be a bit inaccurate based on your water weight. Most fitness experts consider calipers to be the most accurate way to get body composition data even though they're a bear to use. That said, this could be a great long-term monitoring tool if the $299 price tag doesn't scare you off and Wii Fit
just isn't doing it for you.
