Each week consists of three full-body strength workouts. The exact days you do the workouts is up to you, so don’t feel pressure to stick to a rigid routine if you have a busy or irregular schedule. Ideally you’d give yourself a day into between each strength workout, so it might look something like Monday-Wednesday-Friday or Tuesday-Thursday-Saturday/Sunday.
That said, if your schedule is such that you have to (or want to) train on consecutive days, that’s totally fine. One of the great things about full-body workouts is that the volume is relatively low for each muscle group per workout, so we aren’t damaging the muscles to nearly the same degree or causing soreness, so we can train on back-to-back days without worrying about overdoing it.
So all that to say: take a day between strength workouts when you can, but don’t stress if you work on back-to-back days occasionally if your schedule gets jammed.
Along those lines, if life gets busy or you have to miss a scheduled workout for whatever reason, don’t skip that workout entirely. Just pick up where you left off and keep going. If you only get two workouts in one week, for example, just start the next week with Workout 3.
