To start a workout plan with a workout other than the first workout of the plan (which is default), begin by locating a plan that you wish to follow. Then from the workout plan's home page, click "Start this Plan."
In the "Schedule Workout Plan" pop-up window, locate "Choose first workout" and, directly to the right of that option, click on the drop-down list.
From the list, choose the workout that you want to start with. Then select "Next Step " to customize the other details, such as workout schedule and workout reminders.
The workout will appear as "My Current Workout Plan" under the "Me" tab of your Dashboard. Then, when you are ready to log a workout, your plan will begin with whichever workout you chose when you followed the workout plan.
