Hi there, I'll be handling your box challenge critique.
Currently your link leads to a single page rather than all of them, reply to this comment with a corrected link and I'll handle your critique as soon as I can.
To quickly answer your question, how you choose to handle warm ups out of the course is up to you. Warming up will always be beneficial so it's recommended but as you progress you may find exercises more suited to whatever your current task is (maybe a value study if you're planning on painting etc.).
Just keep in mind that Drawabox as a course is here to teach you how to practice - how you use the tools it gives you is up to you, though you'll be better equipped to make those decisions as you progress through the course.
