Since it's inception in 1964, the Pirelli Calendar has been a benchmark for the fashion and art world, although it's still a mystery on who exactly gets their hands on a physical copy. The calendar has gained iconic status due to it's use of the world's best photographers, stylists, make-up artists, and of course models, who combine for a one-of-a-kind product that just oozes sexiness and individuality.

For as long as anyone can remember, people have been looking up to supermodels not only for their beauty, but as the gold standard for fitness and the idea of the perfect body. We've seen a large influx of supermodels taking over the fitness and sports world including Under Armour's signing of Gisele Bündchen, who is now heading up the brand's latest chapter of their "I WILL WHAT I WANT" campaign. We had a chance to talk to some of the 12 models featured throughout the calendar including Isabeli Fontana, Gigi Hadid, Sasha Luss, and Candice Huffine, and asked them about their favorite ways to exercise and stay in shape.

Isabeli Fontana

"I love doing all kinds of stuff, mostly spinning and functional workouts where you use the weight of your own body. It defines your muscles well."

Gigi Hadid

"I box everyday. That's my thing. Even if you're not thinking about one person who you're mad at or one thing that you're punching at, it just gets your aggression out. I always feel happier afterwards!"

Sasha Luss

"I always do pilates, and I love it. It's very good for your body, and it doesn't give you too much muscle. It just gives you a strong, beautiful body."

Candice Huffine 

"Boxing! All models are boxing right now. I have boxing videos on my Instagram. It's become the new kale or something. Time flies by, it's super fun, you don't even know what's going on, and you feel amazing."
