Fashion meets fitness! Celebrity trainer Harley Pasternak sat down with ET to share simple ways to take your workouts to the next level, and surprisingly, it all starts with your outfit.

The fitness guru, whose star-studded roster includes Ariana Grande, Lady Gaga, Kim Kardashian, Rihanna, Megan Fox, Adele, and Katy Perry revealed how the right wardrobe can work out with you while celebrating the opening of Vuori Studio by Harley Pasternak in Los Angeles, California.

“Vuori Studio is designed to be a fully immersive and elevated experience,” he says. “It’s a private, VIP training and recovery space where my clients, brand partners, and athletes can come to move, recharge, and feel their best. We’ve integrated best-in-class equipment with their innovative apparel, so it’s more than just working out.”

And, according to Pasternak, your ‘fit can fuel your fitness from the moment you step into the space.

“What you wear impacts how you move and how you feel. … When you feel good in your clothes and they fit right, move with you, and reflect your personal style it shows. You walk into a gym with a different mindset.”

His go-to brand? Vuori. “It’s performance-driven but also designed to make you feel confident and powerful. That alone can help push you to give more.”

Sporting proper attire also allows Pasternak to teach his A-list approved technique — rooted in science and sustainability — to the fullest extent.

“Great apparel helps you focus on the work, not what you’re wearing. … It gives you the flexibility and support you need during a workout, without distraction,” The Carb Reset author explains.

But your wardrobe is just the beginning. For Pasternak, lasting results come down to healthy habits woven into your daily grind.

“Whether you’re on a movie set, or behind a desk, it’s about building routines that enhance your life, not overwhelm it. … My clients are busy, often traveling, and need programs that are effective, but realistic. I give them the tools to stay healthy no matter where they are or how full their schedule gets,” he notes.

Some of those strategies include walking every day, eating balanced meals, and prioritizing sleep.

“What you do between workouts often matters more than the workout itself. … It’s usually the small things, done consistently, that create the biggest changes,” the nutritionist notes.

“Getting outside and moving regularly, using the PATH method (Palm of carbs, All the veggies, Thumb of fat, Hand of protein), and staying off your phone before bed can do more than any fancy trend,” the public speaker shares.

Feeling hot, hot, hot! Celebrity trainer Shannon Nadj is heating up summer Fridays with her Hot Pilates workouts. 

The workout guru, who has helped sculpt Hailey Bieber, Kendall Jenner, Shay Mitchell, and Shanina Shaik’s bodies, is hosting special classes every Friday from June through August at her studios in West Hollywood, California. 

Think: Reformer and heated mat Pilates sessions in partnership with brands including Next Health, Niagen Plus, Fruit Riot, Splits59, and more, as well as live DJ sets and wellness activations. 

The fitness destination is also hosting hot summer deals with sale through July 4, where clients can purchase a 1-month unlimited membership for $200 heated mat, $350 reformer, or $400 for both. 

Regardless of which option you choose, be prepared to shake and sweat. 

“Get ready to strengthen, tone, and build unstoppable stamina,” Nadj tells ET.

“Each workout blends dynamic Pilates exercises with strength and low impact cardio to challenge your core, legs, arms, and posture. … Expect a strong core, more flexibility, better posture, and a full mind and body transformation,” she adds. 

As for the ideal routine? “Incorporating 2-3 reformer classes per week will allow you to apply the resistance you feel on the springs to your mat workout days,” she suggests.

If you can’t train with Nadj in person, don’t sweat it — you can still get in on the fun by joining the Hot Pilates digital platform.

“Find a community that supports you and one you feel inspired by,” the Pilates expert recommends.
