Press 5x10 (with about 40% of my press 1RM)
I like this better than back off sets in this case because you are getting more frequency with your principal lifts vs. simply more volume (bench and press both respond well to frequency).
Gant, regarding supplementing the main lifts in 5/3/1 with complementary exercise: what IYO would be the equivalents for the Squat and Deadlift days in 5/3/1? Perhaps something like
(or snatch-grip DL? or Power Clean?)
(or maybe Front Squat?)
