Measuring body composition

Important: When you take a body composition measurement, you do the measurement on your TomTom Touch but the result appears ONLY on your phone in the MySports Mobile App or on the MySports website.

To get an accurate measurement, follow the steps below.

1. Wear your fitness tracker for at least 15 minutes before performing a measurement.

   Tip: 15 mins allows the electrode on your wrist to get to skin temperature for an accurate result.

   Important: For an accurate result, take your body composition measurement reading at the same time each day.

2. Wake up your TomTom Touch by pressing the button.
3. Swipe to two screens above the clock screen of your fitness tracker, where you see a percentage sign.
4. Your arms should not touch the side of your body, and your hands and wrists should not touch each other. This can lead to the current taking a shorter path, which can cause inaccurate results.

   

5. Press the button with the tip of your index finger for about 10 seconds, until a check appears on the screen.
6. Make sure you cover the entire button with your fingertip and that your finger forms a straight line with the display of your fitness tracker.

   

   Tip: If you see an “X” on the screen rather than a check mark, try putting a small amount of water on your wrist right under the electrode and on the tip of your index finger.

7. Go to the MySports Mobile app to see your body composition measurement and progress against your goal:

   

   Tap the menu icon, then Progress > Filter button > Body in Activities or select a Body Fat goal by clicking it. You can view your body fat and muscle percentages and the trends over time.

Tips for measuring body composition

• The overall trend of measurements is more accurate if you measure at the same time of day each time.
• The ideal time to take a measurement is in the morning, after going to the bathroom but before eating, drinking, showering, or exercising.
• For women, measurements are less accurate if taken during a menstrual period, as this generally affects the fluid balance in your body.
• Body composition cannot be accurately measured while pregnant or if you have larger metal implants in your body, for example as a result of surgery.
