I did a warm up with 135lbs and my shoulder screamed. Maybe I should have used the bar first and then the warm up weight. No problem though. Like I wrote I have alternatives that are just as good.
I do 10 reps just the bar.
Add two 25s and do 5 reps
Then the two 45s and do 1 rep.
Then go up from there in increments.
What I would do in your case, since you have the shoulder issue, is start with the empty bar and do 3x12 the first day. That's all for the bench.
Then add 5 lbs each workout and keep doing 3x12. Keep adding 5 lbs each workout. This will give your connective tissues time to strengthen.
Right now, your muscles are way stronger than your connective tissues.
Say you bench twice a week, go up by only 5lbs each workout.
Day 1 - bar
2 - bar + 5
3 - bar + 10
4 - bar + 15
Etc.
In ten weeks you will be at bar + two 45s.
Always 3x8-12.
If you can't get 3x8-12 then stay at the same weight until you can.
No need to go lower reps at this stage of the game being old farts.
