Let me be up front: this isn't a program for beginners. You'll be training 5 days per week using high frequencies on the most demanding lifts (the bench press, squat, and deadlift). If you don't have a very good understanding of your ability to recover between sessions, and how to autoregulate your day-to-day training stress, you'll probably struggle with this one.
For those reasons, I can't give you a recommendation for just how strong you need to be before starting on this one, but I suggest that you be able to squat at least twice your bodyweight, bench press 1.5 times bodyweight, and deadlift 2.5 times bodyweight. In addition, ask yourself these questions:
On that note, if you don't think you're quite ready yet, just check out the full Unfuck Your Program course. It covers some beginner-level topics, but it will also help you progress to and through the advanced level. And, since it includes this course, you'll have it for when you are ready!
