Let me say that the routine in the original post can be actually harmful. It should be performed close to the maximum and beginners do no know their maximums. And their maximums also very uneven - muscles here (stabilizers) aren't as strong as muscles there (main muscles) and injuries should be very likely. This routine is more for intermediate-to-advanced types and those already spent a big amount of time in gym.
