Should really wide grip bench be done as an ME exercise or as an assistance for higher reps maybe on DE day?
Alright so would you do it for only 1 set of your 5 rep max or working up to a 5 rep max?
2 x 3, or 2 x 5
or Wide Grip 5 rep max
or Close grip of the floor. etc.. as the main movement.
Hold on a second... I though we were talking powerlifting here... why do you want to do more then 5 reps? I think you need to stick with the 5-3-1 program, or possibly sheko...but that may be WAY too much for you.. its extream....6 weeks of hell, but if you pass the mountain you will come out the other side a man...
You lack bottom end power so I would suggst:
Increase Lat/Back auxilary work
Bench with a cambered bar every other week
Add in dumbell work every couple weeks
Start using dynamic training Speed work and or plyometrics to develop explosiveness
