Who's that fella working on his pecs and delts?

It's Men's Health editor Dave Zinczenko, who was snapped by a spy over the weekend at the Equinox on Greenwich Avenue, a media haven gym (staffers from Radar, In Touch, ABC, CNN, and The New Yorker, as well as the guy behind this website, are among those who sweat there). "He was working out with this hot muscled guy," says our spy. (It's the guy who's back is toward you, not the woman with the cleaning bucket.)

No word on whether The Zinc also worked out those much-talked about abs. Or whether he's like Anderson Cooper, and keeps a towel around his waist while he changes.

(Update: In just the first few minutes this item was posted, we also heard from staffers at NBC, Fox News, the New York Times, and NPR as among other media types with memberships there.)
