Joe Staley's work ethic never was in question during his decade-plus career as the 49ers' starting left tackle, and it appears that determination has continued into retirement.
Staley told ESPN's Emily Kaplan in early July that he already has lost 50 pounds since retiring from the NFL in April, and a picture shared on Twitter by Sports Illustrated's Grant Cohn definitely shows the former offensive lineman's body transformation.

"As an offensive lineman, you're always known as this big, humongous, unathletic blob," Staley said to ESPN. "Offensive linemen get casted in a movie, and they're always 500 pounds. Then you get the opportunity to be healthy again, and all of the effort you used to put into football, you put into that. It gives you a focus once you retire. It's a little bit vain, but I'm starting to see abs that I've always wanted. And it's kind of exciting."
Offensive lineman often must eat an incredible amount of food to maintain the 300-pound frames typically seen across NFL rosters.
Staley seems to be enjoying his retirement.
