The link didn't work for me.
I googled this:
He gives a Strength variation and a Strength and speed variation as well as a washed up meathead one. If you used the 2nd variation there is a day on Saturday for GPP so that day you could pick your finisher from the named workouts if you wished. Otherwise I'd recommend sticking with what Defranco has recommended.
It seems pretty crazy that people are already adding things to programs or changing them in a manner that it doesn't look like the program anymore when you are done. Give the WS4SB an honest run through as he has laid out first for a few months and then go to your variation if you needed. by the end of a few months.
