A Viral Workout That Raised Eyebrows

In a world where gym bros live in sweat-wicking leggings and neon trainers, one man dares to defy the fitness fashion police with a sartorial choice so bold it’s sparked a social media frenzy. Enter Robert F. Kennedy Jr., the 71-year-old Health and Human Services Secretary, whose penchant for pumping iron in denim has left the internet gobsmacked. When a video of RFK Jr. crushing a workout in blue jeans alongside Defense Secretary Pete Hegseth went viral, the question on everyone’s lips wasn’t about his push-up prowess but something far more pressing: Why on earth is he working out in jeans? On August 20, 2025, Fox News’ Jesse Watters dared to ask the question that had X users in a tizzy, and RFK Jr.’s response was as surprising as it was strangely sensible. Buckle up, because this tale of denim defiance is one for the ages, blending fitness, fashion, and a touch of Kennedy quirkiness that’s got America talking.

The viral moment came courtesy of the “Pete and Bobby Challenge,” a testosterone-fueled fitness gauntlet that saw RFK Jr. and Hegseth, 45, tackle 100 push-ups and 50 pull-ups in under 10 minutes. Part of President Donald Trump’s “Make America Healthy Again” campaign, the challenge was meant to inspire the nation to ditch the couch and embrace the sweat life. But while Hegseth rocked standard gym shorts, RFK Jr. strutted into the Department of Defense gym in his signature jeans, a belt cinched tight, and a grin that said, “Yes, I’m doing this my way.” The internet exploded. “RFK Jr. working out in jeans and a belt is absolutely diabolical,” one X user quipped. Another mused, “Do you think RFK has workout jeans and casual jeans, or does he just freeball and take his musk everywhere?” The memes were relentless, but the mystery remained—until Watters got the scoop on Jesse Watters Primetime, and RFK Jr.’s explanation turned heads.

The Denim Dilemma: Why Jeans?

Picture the scene: Jesse Watters, with his trademark smirk, leans forward and asks the question burning in the minds of fitness fanatics and fashionistas alike. “Before we get started, I have to ask you a question that everybody’s wondering about,” he says, barely containing his glee. “Why do you wear jeans when you work out?” The camera pans to RFK Jr., who doesn’t miss a beat. “Well, I just started doing that a long time ago because I would go hiking in the morning and then I’d go straight to the gym,” he replies, cool as a cucumber. “And I found it was convenient, and now I’m used to it, so I just do it.” Watters, clearly delighted, nods approvingly. “There were a lot of theories, but that makes perfect sense,” he declares, as if RFK Jr. had just cracked the Da Vinci Code.

At first glance, it’s an answer so simple it’s almost infuriating. Hiking in jeans? Gym in jeans? Who does that? But dig a little deeper, and RFK Jr.’s logic starts to shine through like a freshly polished belt buckle. The man’s a creature of habit, a rugged outdoorsman who’s been scaling mountains and casting fishing lines in denim for years. Social media posts show him hiking Colorado peaks, fishing in Idaho, and even swimming at Rock Creek Park—all in jeans. For RFK Jr., denim isn’t just clothing; it’s a lifestyle, a practical choice born from a life on the move. “I found it was convenient,” he said, and you can almost picture him shrugging off the haters as he deadlifts in Levi’s.

But let’s be real: jeans aren’t exactly the go-to for burpees and bench presses. Denim is heavy, rigid, and about as breathable as a plastic bag in a heatwave. When USA Today’s David Oliver tried to emulate RFK Jr.’s denim workout, the results were grim. “I regretted the choice,” Oliver wrote. “The humidity seeped into my pores, and beads of sweat pooled all across my body. Including my denim-covered legs.” Ouch. Yet RFK Jr., with his chiseled physique and enviable stamina, makes it look effortless. How? Is it sheer Kennedy grit? A secret stash of stretchy jeans? Or just a man so comfortable in his own skin that he doesn’t care what the gym bros think?

The “Pete and Bobby Challenge”: A Fitness Revolution in Denim

The “Pete and Bobby Challenge” wasn’t just a flex of RFK Jr.’s denim-clad muscles; it was a bold statement in Trump’s “Make America Healthy Again” (MAHA) campaign, a push to get Americans off their sofas and into shape. Filmed at the Department of Defense, the challenge saw RFK Jr. and Hegseth—both known for their larger-than-life personalities—pushing their limits with 100 push-ups and 50 pull-ups in a blistering 10 minutes. Hegseth, a former Fox News host turned Defense Secretary, was all in, sporting athletic shorts and a determined grin. RFK Jr., meanwhile, rocked his jeans like a cowboy at a CrossFit convention, proving that denim doesn’t slow him down.

The challenge, posted on X on August 18, 2025, went viral faster than you can say “squat rack.” “President Trump set the example by putting forth efforts to make America healthy again,” Hegseth declared on X, alongside a clip of the duo sweating it out. “That’s why we are introducing the Pete and Bobby Challenge. 100 push-ups. 50 pull-ups. 10 minutes.” Transportation Secretary Sean Duffy even jumped on the bandwagon, tweeting, “I’m up for the challenge! Let’s MAHA.” The initiative, tied to Trump’s executive order to revive the Presidential Fitness Test in schools, was a hit—except for one detail: RFK Jr.’s jeans.

Social media erupted with equal parts admiration and bewilderment. “RFK Jr. in jeans doing pull-ups is the energy I didn’t know I needed,” one user posted. Another wasn’t so kind: “This is not right. It’s like wearing a Speedo to church.” Even Fox News’ Greg Gutfeld couldn’t resist a jab, quipping, “Somebody’s gotta raise this question. Why does RFK wear jeans when he exercises? It’s like the third or fourth time. It’s all the time.” But RFK Jr. was unfazed, taking to X to double down: “People keep asking why I wear jeans when I work out—but no one bothered to ask ME. @JesseBWatters finally did…” with a clip of his Fox News explanation. The man’s got swagger, and he’s not afraid to own it.

A Denim Legacy: Not a New Look for RFK Jr.

If you thought the “Pete and Bobby Challenge” was RFK Jr.’s first foray into denim workouts, think again. The man’s been rocking jeans in the gym for years, and his social media is a treasure trove of proof. In June 2023, when he was still a Democratic presidential candidate, he posted a shirtless clip on Instagram, grinding out push-ups in jeans with the caption, “Getting in shape for my debates with President Biden! And yes, I can do more than 10 push-ups. That was my last set.” Fast forward to December 2024, as he prepped for his Senate confirmation hearings, and there he was again—jeans, no shirt, “practicing moves for my confirmation hearing.” The guy’s consistent, we’ll give him that.

His denim obsession extends beyond the gym. Photos show him scaling Arizona’s Camelback Mountain in a sweat-soaked teal T-shirt tucked into jeans, belt and all. He’s fished in Idaho, hiked in Colorado, and even swam in jeans, leaving fans wondering if he owns a single pair of sweatpants. “It’s not just workout jeans,” one X user joked. “It’s life jeans.” Another speculated, “Maybe he’s got a secret deal with Levi’s.” Whatever the reason, RFK Jr.’s denim devotion is as much a part of his brand as his vaccine skepticism and environmental activism.

The Kennedy Conundrum: Why It Works

So why does RFK Jr.’s explanation make sense, as Watters so enthusiastically claimed? It’s all about context. RFK Jr. isn’t your average gym rat. He’s a lifelong adventurer, a man who’s spent decades hiking, climbing, and living an active lifestyle. For him, jeans aren’t a fashion statement—they’re practical. Hiking in the morning, hitting the gym by noon, no time to change? Jeans it is. Over time, what started as convenience became a habit, a quirky hallmark of a man who doesn’t care about convention. “I found it was convenient, and now I’m used to it,” he said, and there’s something oddly endearing about that simplicity.

But let’s not kid ourselves—jeans aren’t ideal for workouts. Fitness experts have weighed in, and the verdict isn’t kind. Denim restricts movement, traps heat, and can chafe like nobody’s business. “It’s not something I’d recommend,” said one trainer in a Salon piece, noting that denim’s rigidity could hinder performance and increase injury risk. Yet RFK Jr., with his sculpted arms and marathoner’s stamina, seems immune to these drawbacks. At 71, he’s fitter than most half his age, cranking out pull-ups and push-ups like it’s nothing. Maybe there’s something to this denim thing after all.

His explanation also taps into a broader Kennedy ethos: authenticity over optics. RFK Jr. has never been one to bow to expectations. From his controversial stances on vaccines to his defection from the Democratic Party to join Trump’s cabinet, he’s a man who charts his own course. Wearing jeans to the gym? Just another way to say, “I do me.” And in a world obsessed with curated perfection, there’s something refreshing about a public figure who doesn’t care if his workout gear raises eyebrows.

The Backlash and the Buzz

Of course, not everyone’s buying the denim defense. Critics on X called his explanation “more confusing than clarifying,” with one user snarking, “Hiking in jeans is just as weird as working out in them.” Others questioned the practicality: “Who hikes in denim in Arizona heat?” Salon’s Alex Galbraith noted that RFK Jr.’s reasoning “only raised more questions,” pointing out that denim isn’t exactly hiking-friendly either. And then there’s the hygiene factor—does he wash those jeans daily, or is he just embracing the “musk,” as one X user so delicately put it?

The controversy isn’t just about fashion. RFK Jr.’s tenure as Health Secretary has been a lightning rod, from his COVID-19 vaccine restrictions to comments on autism that sparked outrage. His viral workout with Hegseth, a former Fox News host who’s faced his own scandals, only added fuel to the fire. Critics see the “Pete and Bobby Challenge” as a publicity stunt, a distraction from policy debates. Supporters, meanwhile, hail it as a bold move to inspire fitness in a nation battling obesity. Either way, the jeans stole the show.

A Personal Life Under Scrutiny

Beyond the gym, RFK Jr.’s personal life has also been under the microscope. Rumors of strain with his wife, actress Cheryl Hines, 59, have swirled since he joined Trump’s cabinet. In a Wall Street Journal interview, Hines brushed off the speculation, saying, “Bobby and I talk about everything, so that’s how we move through everything. We’re really good friends, and we trust each other.” But the jeans? Even she might raise an eyebrow at those. Still, Hines’ support underscores RFK Jr.’s ability to weather storms, denim-clad or not.

His Senate confirmation in February 2025 was no cakewalk either. Despite opposition from his cousin Caroline Kennedy, who called him unfit for the role, RFK Jr. squeaked through with a narrow vote. His jeans-clad workouts during the confirmation prep became a quirky footnote, a symbol of his defiance in the face of critics. “Practicing moves for my confirmation hearing,” he captioned one clip, proving he’s got a sense of humor about the whole thing.

The Denim Legacy Lives On

As the dust settles on the “Pete and Bobby Challenge,” one thing’s clear: RFK Jr.’s jeans aren’t going anywhere. They’re as much a part of his brand as his Kennedy name or his MAHA mission. Whether he’s hiking, fishing, or cranking out pull-ups, denim is his armor, a middle finger to convention in a world that loves to judge. And let’s be honest—there’s something oddly inspiring about a 71-year-old who can out-push-up most of us while wearing pants better suited for a barbecue than a bench press.

Will the “Pete and Bobby Challenge” spark a fitness revolution? Maybe. Will it inspire a denim workout trend? Probably not—USA Today’s sweaty experiment proved that. But RFK Jr.’s explanation, delivered with that Kennedy charm, has given us a glimpse into a man who’s unapologetically himself. “It makes perfect sense,” Watters said, and for once, we’re inclined to agree. In the grand tapestry of American weirdness, RFK Jr.’s jeans are a quirky thread, and we’re here for it. So, here’s to the Health Secretary who lifts weights, defies norms, and makes d
