My 5 rep max for the bench press has progressively gone downhill over the last year or so. I started with SS for 3x5 of 217 @ 210 lbs and now I'm somewhere around 1x5 of 200 @ 176 lbs while on Madcows 5x5. While I totally understand cutting is going to hinder any strength gains, I'm still around 19% bf and my other lifts have continued to increase. Below is a form video I recently posted - since this I have widened my grip and am learning to setup my arch with flat feet.
I've read that people typically respond to a higher volume of bench press movements? Would that be a good way to go (ie add an additional set or two or even add in a back-off set)? Or would it make more sense to add in an additional bench press accessory lift for a couple sets? Ideas would be helpful - thanks in advance.
