Maybe I can help to clarify a bit more on this topic… Thank you @BCrossen for the previous clarifications - all spot-on! Here are some additional tidbits to consider.
Why we built it like this:
The way plans are built takes a lot into consideration, including how to progress an athlete appropriately in each training zone, where the athlete is in their plan, and what their goals are. The plans also balance the order in which workouts are prescribed, also based on the zones targeted. We don’t recommend moving workouts out of order for both of those reasons. That said, we know that life happens, which is exactly why we built AT.
AT can probably handle what you might be trying to accomplish with moving your workouts. Here are some examples.
If you know you won’t be able to work out on a certain day, AT addresses that. Just add a ‘time off’ annotation on the day or range of dates where you know you can’t train. To do this, click “+” on Calendar, add annotation, and choose Time Off as the annotation type. Opt to adapt your plan when prompted.
If you had an unforeseen conflict arise and had to skip a workout (i.e. unplanned time off), just skip the workout, and the next day AT will adapt your plan appropriately. (This may not always trigger an adaptation, because there are circumstances where you wouldn’t need to change your plan just because you missed one workout.)
If you want to do a different workout from your scheduled workout on a certain day (e.g. change duration), wait until that day, then load and complete a different workout with the desired duration and level. AT will take the completed workout into consideration with calculating your Progression Levels, and will make sure that future scheduled workouts in that training zone reflect any changes in your levels.
If you want to do an extra workout that wasn’t on your plan, go ahead and add that to whatever day you plan to complete the workout, or simply load and complete the desired workout on the day in question. AT will take the completed workout into account when computing your Progression Levels, and will make sure that future scheduled workouts in that training zone reflect any changes in your levels.
If you’re used to manually adjusting your plan to adapt around life’s uncertainties, it can feel weird to sit back and let AT do the heavy lifting. We made AT to automate how so many athletes need to manually adapt their own plans. We want to help you save time and decrease the mental stress that goes along with making these kinds of changes manually, both the mental load of having to make the changes and the stress of possibly second-guessing the changes you make.
Try giving AT a chance to handle these kinds of situations, and see how it goes!
