Looks like we weren't the only ones who thought Nick Jonas looked magnificent in that sexy shirtless selfie he posted back in July -- the editors of Men's Fitness took notice, too!

The magazine is featuring the buff Jonas Brother in an upcoming issue, and is giving fans a taste of what to expect from the spread with a new behind-the-scenes video. Nick is seen sporting a couple of different outfits, but we think everyone's fave is going to be the black tank that shows off his massive shoulders, especially as he does pushups for the photographers and swings a guitar around.

The singer also answers a few questions from Dean Stattmann, the magazine's deputy editor, including how he manages to keep so fit with such a demanding schedule. "When you're on the road or you have a busy schedule -- not just for us, but for anybody -- you really have to think about it that much more," Nick answers. "So, we build a gym where we can when we're on the road, if we have certain things we can use. And when it comes to eating right, we just try to find those places in some of those random cities we're in that we can get the thing we need."

Jonas, who's dating Miss Universe 2012 Olivia Culpo, also talks what it's like seeing someone so publicly.

Speaking of social media, Nick today (Sept. 23) tweeted that he's off to the islands to shoot a TV show:
