When your personal trainer or fitness coach sets up your account, they will create your password for you. To change your password, click on the Account button in the top right portion of your screen. Once you do this, a pull down menu will appear. Click on the Profile button to continue. (See image below.)
Once you are on the Profile page, you will see an option to change your password in blue. It is titled Change Password. Click this button and enter in what you would like your new password to be. Then, click Update Password. Once this is done, you are all set (data is automatically saved).
