My understanding is that the only warmups are those in Lesson 1 and additional pages which get explicitly added to your list by instructors as you complete lessons. I'm on Lesson 5 and I've been instructed to add extra warmup page options into the rotation.

• Boxes (like 250 box challenge)

• Organic Forms

• Organic Arrows

I have not been instructed to add any demos or repeats of other lesson material.

While technically every exercise should be included as part of your regular warmup rotation, the constructional drawing exercises which make up the bulk of lessons 3-7, are an area where we leave it up to the students in terms of whether or not they include them in their warmups. Part of this is because they're considerably more involved than the basic exercises, but moreover since lessons 3-7 themselves involve doing constructional drawing exercises (the subject matter may differ, but it's still ultimately the same exercise just seen through different lenses), they're not exactly in a position to be left behind.

I expect that most students leave them out of the warmups themselves and instead focus on the other exercises we introduce throughout the course (those from Lessons 1 and 2, from the box/cylinder challenge with their line extensions, and the leaves/branches from Lesson 3). I do not however say this explicitly in the lesson material because I don't want students who want to include those kinds of things in their warmups to avoid doing so.
