In the Mobile App you are able to set a Workout Reminder for yourself, so you will receive a notification at the time you've chosen.
To turn this on or off, open the app, open the menu and click on Account Settings.
Once there, scroll all the way down and you will see the 'Workout Reminder Notification'.
This option can be set on and off.
Once enabled, you can choose a time when you want to receive the workout reminder notification.
