I have been through 5 cycles on beyond 5/3/1 program here are my results:
35lbs on my squat (just did 480 raw yesterday)
5 on my bench maybe (I'm at about 390 now)
30lbs on my strict overhead (at about a 240 max)
30lbs on my deadlift (550 dead about)
I have been lifting consistently for 25+ years and drug free. I have increased my food and protein intake and put on 15lb slowly over the many months I weight 262 now. The bench improvements haven't been that great but with the way the other lifts have increased it's definitely worth it. I will try to tweak a few things on bench so I can get some better results but my overhead press has improved enormously.
