"Well, you're never going to," he said. "After back surgery, it's like after any surgery. I think you're always going to have to work hard at that. Not everyone knows, but once you have a back surgery, you kinda have to change the way you do things. You have to constantly work on your glutes, your hamstrings, your abs and strengthen everything around that area.
"That doesn't mean you can't do the things that it takes to be successful on the field or whatever you want to do. There's just been plenty of people that have done it, so you just gotta go do it. It just takes work."
Romo said earlier this month that he is "miles ahead" of where he was last year coming off his first back surgery.
"I'm 100 percent, it's just -- you have to always work at something, if that makes sense. You'd like to be smart coming back. If it was up to me, I would go and do everything, and then all of a sudden, 'You're done!' You've done too much."
