What is a Focus Week?
One position, one week. That is the whole idea.
You pick a single focus, and the app gives every class a job: a challenge before you train, a check-in after. The target is three focus sessions in the week. Hit fewer and the app recommends rolling the focus into a second week, because proof takes reps.
You can change focus early from the focus screen, but the system works because you do not. Prove it or disprove it, then move on.
