I am a big fan of the 5/3/1 routine, will try out this revised version that Jim Wendler posted earlier this year, looks very interesting and fun
It is done 4 days per week, and three cycles long. First month assistance 5 x 10 @ 50%, second month assistance at 5 x 10 @ 60%, and third month assistance at 5 x 10 @ 70%. Plus you mix up the assistance lifts, like Squat days you do Deadlift assistance, and Bench Press day you do military press assistance.
Last sets on the 5/3/1 are not taken to failure; only the required reps are done
I will do these 4 days;
Sunday = Deadlift
Monday = Bench Press
Wednesday = Squat
Thursday = Military Press
