Give this a try...between 135 and hog wild...throw in a couple of sets at 170 or so. Don't shoot your nut, stop before you are really pushing. I found I am stronger on my work sets when I do this. Gets all your synapses firing. I used to akways feel I should. Have got more out of my sets, I wasn't "ready"
Here is what I do on chest days twice weekly. Typing on iPhone with my sausage fingers.....
Stretch smith m with bar at highest setting all sorts of twisting turning pulling
Then with 5 lb dumbbell using bench I hold up and start doing circles until full ROM
I circuit my flat incline decline
Start with bar for fast movements about 25 reps or so both on flat incline
Do 60 dumbs for 8 on incline
Do 135 F&D for 10 or so
Incline 70 for 6 to 8 rest and for 3 more
185 for 6 flat stay at 135 on decline 10+
Incline 75 for 4/5 top of pyramid then later 3 sets down to 55
Flat 225 for reps as much as I can push then pyramid down to 135 close grip about 4 more sets different weight
Decline to 155 for 10 the pyramid you get the idea
Last set flat till full failure on 135.
Then polish with cable machines
