I have a right shoulder injury from years ago that inhibits my benching and military presses. So, I haven't seriously benched in years. However, I still do standing militaries, but I use a leg machine that allows me to press at a slight upward angle. That takes some of the stress off my shoulder and it works quite well.

I would never have surgery unless I was in dire pain. I have a sports hernia that gives me some pain from time to time, but I won't have surgery. I just don't do any direct ab work. Sometimes I have to lay off a movement for weeks, even months to allow the injury to heal. That's the price you pay, but it's better than surgery.
