It's called the "LoHiLo Routine" because you will be alternating between low rep, high weight days and high rep, low weight days.
I've been running this program myself for over a year now and have experienced impressive results. I do warn you, it is a very hard routine. If you aren't willing to push yourself throughout the entire workout then it is not for you.
I have made two videos of the LoHiLo. The shorter video briefly explains the routine. The longer video goes through every single exercise of the routine for you. Please check them both out.
