You’re 190 pounds of pure muscle, right? Find out just how fit (or fat) you really are by stepping up to the new
Tanita UM-026 ($89.95)
home scale. Using a technique called bioelectrical impedance, the scale determines both your body-fat percentage and your hydration levels within seconds. Electrode footpads emit a small, safe signal that zips through water-rich muscle tissue and slows when it hits fat. Given the amount of time the signal takes to come full circle-plus your height and weight measurements-the scale calculates both your flab factor and whether or not you should drink more water before heading out to the hill.
