Should I use the Athlete mode?
If you are a bodybuilder or have strong muscles, you need to select the Athlete mode in your settings. The normal mode doesn’t work well with very muscular users. Body fat and other body composition results can be way off when muscular users are not using the Athlete mode.
Please note that not all Smart Scale models or Mobile Apps versions support the Athlete mode. To select the Athlete mode, go to the “My Account” screen then tap on your profile image. You can set to the “Athlete mode” on your “Profile” screen.
