The Perfect Fit

GQ's Body & Style workout plan.

You've already resolved that 2017 will be the year you finally get in biceps-pumping, squat-thrusting, seam-splitting shape. The only question is: Uh, how? Here with the answers—and with suggestions on what to wear while you're at it—is ridiculously handsome math-professor-turned-fashion-model PIETRO BOSELLI.

Pietro Boselli has had a crazy couple of years. While finishing his Ph.D. in mechanical engineering at University College London and, you know, “working on the computational design of large steam turbines,” Boselli found himself the subject of a viral Internet story.

He'd been lecturing for an undergrad math course, just your average math professor with the body of a Roman god, when a few of his students realized their hunky prof was a bona fide model and took to Facebook. E! News made it a story, and then everyone from Elle to The Guardian picked it up. Boselli, 28, was dubbed “the World's Hottest Math Teacher.”

“I was just living my life,” he says today. “This is something that can only happen with the Internet, obviously.”

Since then he's become one of the most in-demand models, shooting campaigns for Dsquared2, Moschino, and Armani's sportswear label, EA7. “I couldn't be just a model,” he says. “I don't see myself as one thing. I'd like to have my own engineering firm.” He plans to start his own activewear label, too. Simple stuff like tank tops and shorts. Down the line, maybe he can expand into wearable technology: “Clothing you can plug in and have the electricity clean it,” he says. “Or fragrance-encapsulation technology. It could be done. But you need much bigger capital.”

We're not worried about him finding work. “I'm a very confident person,” Boselli says. “I'm very confident in my abilities.”

You would be, too, if you had his body. So here's exactly how to get it—and the clothes you'll need to show it off.

Killer Gym Style Starts in the Streets

Activewear has infiltrated the fashion Zeitgeist so thoroughly that Prada, paragon of sartorial refinement, is now unveiling its own version of athleisure. (These technical joggers and this ice-cold jacket marched down the runway, replacing all those suits.) There are two reasons for this sportification—and it's a chicken-and-egg-type deal: Guys are wearing performance gear in more and more situations, and the gear is getting more and more stylish. Which means you can dress like an athlete, even if you think deltoids are a Florida State fraternity.

The Day-Glo-Tights Era Is Officially Over

Neon gym gear went out of style faster than dubstep. Today's thinking: Strive for the same taste and restraint at the gym as you would anywhere else. That means a more sophisticated, less workout-y palette. Think grays, blues, and blacks. Just, please, no white tights.

The First Step to the Chest You Want

Why do all superheroes have big block graphics on their chests? It's a simple lesson in optics: Chest graphics add a few orders of magnitude to your pecs' appearance. If you decide to borrow this sartorial sleight of hand, stick to darker colors and skip the primaries—you don't want to look like an actual superhero.

You Can't Wear Out the Classics

On arm day, it's hard to beat the freewheeling, mobility-maximizing tank top, a throwback to the old days of bodybuilding. Just make sure it's in a technical fabric made for exercise and not its inbred cousin, the cotton wife-beater. (Man, that term is ready for retirement.) Then pair your tank with another classic: fitted gym sweatpants.

Pietro's Principles

If you wanna get as ripped as this guy, there's more to it than pumping iron. A few tips from the man himself:

  1. Bring your gym clothes everywhere. You'll be more likely to have a spontaneous workout than a spontaneous nacho platter.
  2. Put your phone in your locker and stop hitting on all the girls in yoga class. “I don't go to the gym to socialize,” Boselli says, “so I can usually be out in 45 minutes.”
  3. Don't do cardio at the gym: Run outside, play sports, hike. Nothing's more absurd than driving to the gym to hop on a StairMaster.
  4. If you really want to take your body to the next level, build up to two-a-day workouts. Yes, really.
  5. Pasta. Eat a lot of pasta. Then chase it with some pasta. The carb truthers are worse than the climate-change truthers.

Always Wear Clothes That Will Get You Spotted

This handsome shirt right here is from our favorite new apparel brand, Fourlaps. Based in New York, the line is all about understated style, which is why it's not covered in tacky logos. It's also sweat-wicking and odor-resistant, which your bench partner will appreciate.
