The video is a good idea but needs tweaking to make it user friendly.
At the moment you couldn't run it without having the UpUYpUp plan open in-front of you as well. It doesn't say what gear you need for some of the intervals until you start it.
For example at 14.06 it goes into a rest period and just says "next, seated rolling", but nothing about gear selection. That only appears once the interval has started.
Hope that helps
