WHY TRACK BODY COMPOSITION?

Being fit is more than a number on a scale. Body composition is a great indicator of how fit you are and the shape you’re in.
Find out what works for you by seeing how your muscle mass and body fat percentages change over time. Track your progress towards your goal, whether you are trying to lose fat, get fitter or simply shape up.

How does it work?

TomTom Touch Cardio + Body Composition fitness tracker uses the same technology as connected scales: BIA, or bio impedance analysis. Your trackers calculates your body fat and muscle mass by sending a harmless current through your body and measuring how much resistance the current encounters as it makes its way through your body.

WHEN SHOULD I TAKE A MEASUREMENT?

Body composition can be measured any time but many factors, such as exercise, eating and hydration levels can influence a single measurement and cause daily fluctuations. Try to measure it every day at the same time and to be properly hydrated to get a more accurate reading.

HOW TO TAKE A MEASUREMENT

  • Wear your tracker for at least 15 minutes.
  • Swipe to the body composition screen on your tracker, which is indicated by a % sign.
  • Place the index finger of your opposite hand on the touch button.
  • Make sure to cover the entire button with your fingertip and that your finger is parallel to the display of your tracker.
  • Your arms should not touch the side of your body, and your hands and wrists should not touch each other. This can cause an error.
  • Hold that position for 10 seconds until the device displays a tick sign.
  • To see the result, open the TomTom Sports App and sync the device with your phone. The result will be displayed in the app.
