Ben Affleck, Jennifer Garner Brentwood lunch '66 Chevelle SS

Well, maybe it wasn't that romantic, but judging by the smiles on their faces, the happily married couple certainly had a good time catching up!

Ben cruised around in his 1966 Chevelle SS 396 while Jen opted to ride her mom SUV, but forget his sweet vintage ride -- we can't stop staring at his bulked up physique! So what exactly has he been doing to get so beefy?

Turns out, he's been working out with Rehan Jalali, who got him in tip top shape for his role in The Town. We'll NEVER forget Ben's pull-up scene in that movie ... ooh la la! (If you don't know what we're talking about, please do a Google image search for "Ben Affleck pull up The Town" ASAP.) The other day Jalali tweeted, "Quick Update: Met up w/Batman and Operation Biggest/Leanest/Baddest Batman Eva is on schedule! #DarkKnight."

He may be the hottest Batman ever, but will be the best? Remember, he's basically competing against Val Kilmer, Michael Keaton, George Clooney and Christian Bale ... that's a pretty tough crowd!
