As the ideal body composition can vary a lot from person to person, we cannot give you an accurate estimate for this. The TomTom Touch is designed to help you get a better picture of how your health and body changes over time. In order to facilitate this, we provide you with a graph showing changes to your body composition numbers for a selected time range. You can view this graph on the MySports website and in the MySports mobile app in the Progress tab.
You can also set body goals, such as a certain weight or fat percentage by selecting Goals on the website or in the app. Once a goal is set you can view your progress towards this goal alongside your other activity data.
If you would like personalised advice regarding your body composition, we recommend consulting a licensed personal trainer or medical professional.
You can find more information about body composition in this article from the American College of Sports Medicine, as well as other online resources.
