These days, the hottest celebrity hang is on the Internet and it kicks off each morning at 11 a.m. 

That’s when Isaac Calpito, the sparkly yoga tight-clad, Broadway-trained pro responsible for Vanessa Hudgens‘ and Lisa Rinna‘s sculpted shapes, turns up the Taylor Swift and his (sometimes expletive-laced) charms as he leads some 2,500 devotees through his sweat-inducing, booty-toning Torch’d workout on Instagram Live. 

The 45-minute sessions, filled with leg circles, hip pulses and crunches are free (and live on his feed for 24 hours, during which upwards of 17,500 more exercisers partake). And sweating it out right now, may provide a mental release that has never felt more necessary. But the Hamptons-based pro does make one request, asking those that are able to donate whatever they can to No Kid Hungry. 

In the 12 weeks since his first March 17 session, he’s raised more than $240,000. 

“I offered it basically to connect with my clients first. You know, because we’re in quarantine,” he explains to E! News of his transition from devoted trainer to viral sensation. “Second day it was like, ‘Hi, I’m from Guatemala. Hi, I’m from Portugal. Hi, I’m in Germany.’ I was like, what? And they keep coming back. I quickly saw an opportunity to make it even more impactful.”

Having grown up with his mom working three jobs to keep food on the table, No Kid Hungry, is immensely personal to Calpito. “A child not knowing where their next meal is coming from is, devastatingly alarming and shouldn’t happen,” he stresses. “You know, it’s 2020, let’s get it together.” His initial goal was a relatively humble $1,000: “We reached that in 15 minutes.” 

Calpito knew he had something when his West Side Story castmates began joining in on the pre-show routine he’d put together simply because he didn’t have time to pop out to his favorite Pilates class.

“I was like, you know what, I need to create some something for me that’s 45 minutes to an hour that I can stay fit, stay lean, and yet still be able to immediately perform and be in tip top shape,” he says of the moves he’d do right on the Palace Theatre stage. “I would have my little boombox and I would just do it alone. Slowly but surely the entire cast started joining it. Wow. And so I started, like, directing and, and calling cues out and I saw people’s bodies change and word of mouth happened.”

These days, endorphin-seekers are apt to see everyone from Jessica Chastain to Kelly Ripa adding their commentary to the IG sessions between forearm planks. Rinna, who like Hudgens has joined Calpito for sessions on split screen) recently told The New York Times that she plans her entire mornings around the classes that have left her butt better than ever.

“It gives me something to look forward to,” she told the paper. “I don’t like to work out by myself, I’m a class girl and at the end, I feel like I’ve just been to a boutique fitness class.”

Part of that is what Calpito calls “the magic sauce,” the community feel created through the constant commentary. “The live streams are so over-the-top and hilarious that people are like, ‘It’s really hard. But I’m like laughing my ass as off,'” he shares. “People are making friends with people they’ve never met just because they see the same names.”

Plus, you know, they’re getting fit AF.

“It is a 45-minute to an hourlong flow of body resistance-targeted reps,” he explains. “It was created without weights because the idea is that you can do it anywhere without anything.”
