when doing antagonistic pairings you don't have to have equal weight for each exercise.
Meaning you don't have to have this:
A1) BB Bench 115 lbs
A2) BB Rows 115 lbs
You do however have to do the pairings with equal intensity. . . meaning if you were doing a 3x8 you'd need to use approximately a 10RM. Don't slack on one exercise for the sake of the other. They should be equally tough.
I hope that made sense, and good luck on Muscle Revolution. . . . also you could check out my training log entitled "This is My Muscle Revolution" (link below) for an example.
