When setting up your account, your personal trainer or fitness coach may have selected a profile picture for you that you wish to change. To change your profile picture, click on the Account tab in the top right portion of your screen. A pull down menu will appear after you click on it. You must then click on the Profile button. (See image below.)
Once you are on your profile page, you will see a button labeled Update Profile Photo. Simply click that button, choose the photo you would like to be your profile picture, and click Open. After this, you are all done (your data is automatically saved).
