Sometimes it's necessary to take an extended break during a program. In this case there are 2 options:-
Move each session from the current scheduled date as you perform it, or
Update the program settings to reflect the new start date and start session
We will focus on option 2 here.
Navigate to My Programs (through My Training) and edit the active program(s) you want to change Set the Start date as the date you will resume training and set the Starting session to be the session you will perform. Click update and the Schedule should now reflect these settings.
