I used to bench with dumbells. I used to bench 280 (2 140 dumbells) for 3 sets of 10 reps. For whatever reason, benching with a barbell would cause serious shoulder issues and i could never bench as much with a barbell eventhough most could do more with a barbell.
Now i am back down to 220, but working my way back up.
I never tried to bench my absolute max for fear of reinjuring a labrum tear i had years ago.
I weigh in at 185.
Guys that can bench twice their own weight area
