I've got opinions of course
But before I voice mine I'd like to hear your thought's on it, IK.
I would advize you though, Hunter, to at least try the basic weight warmups techniques first without the extra heavy load at the end. It never really makes sense to go from not enough to more than enough. All this potentiation stuff, as I was getting into before, as far as research has mostly been studied prior to explosive type movements. However it would make sense there could be some benefit regardless since anything that increases peak power output has potential here. But the important thing to consider is that it mostly seems to work on highly advanced lifters. Like I said before I don't know if it is because of more resistance to fatigue, or a more mature neural response. Although I would surmize that because of a more robust nervous system reaction, the more advanced lifter simply gains an immediate fitness effect which more than offsets any fatigue effect. But the the less strong lifter, fatigue is greater and it seems to actually decrease power...although of course this is all individualistic and it would depend on just how much you do.
Just in general, though, I would shy away from it for "beginners".
