In the rapidly evolving landscape of digital entertainment, a new medium is capturing the attention of a generation that has largely abandoned traditional linear television. Vertical media—short-form, mobile-first, high-stakes storytelling—has found its poster child in actor and model Chase Mattson. Recently crowned People magazine’s "Sexiest ReelShort Star," Mattson has transcended the typical boundaries of digital content, positioning himself as one of the industry’s most versatile and physically disciplined performers.
His latest project, Agent of Shadows, a high-octane collaboration between ReelShort and WWE, serves as the ultimate test of his mettle. By stepping into the squared circle with professional wrestling royalty, Mattson has demonstrated that the modern actor’s toolkit requires more than just charisma; it demands the conditioning of an elite athlete.
The Rise of the Vertical Micro-Drama
The premise of vertical media is simple: satisfy the insatiable appetite of younger audiences who consume content primarily on smartphones. By shooting shows vertically, creators eliminate the "rotate phone" barrier, offering a seamless viewing experience that fits perfectly within the social media scrolling loop. However, this accessibility masks a grueling production reality.
ReelShort dramas are designed to hook viewers instantly, offering a handful of free episodes before a paywall dictates the narrative’s resolution. For Mattson, this creates a pressure-cooker environment. Every second on screen must be compelling; there is no room for "slow burns" or filler scenes. As one of the genre’s most sought-after actors, Mattson has mastered the art of the micro-performance, ensuring that his physical presence and emotional delivery remain sharp, regardless of the format.
Chronology: From Modeling to the Squared Circle
Mattson’s trajectory toward becoming an action-oriented lead was not overnight. Initially known for his success in the fashion modeling world, he realized early on that the aesthetic requirements of a model—often requiring a lean, sometimes underdeveloped physique—were antithetical to his goals as a lead actor.
His transition into the world of WWE-produced micro-drama brought him face-to-face with the literal giants of professional wrestling. Agent of Shadows features a powerhouse lineup, including Drew McIntyre, Booker T, Jacob Fatu, and Nikkita Lyons. The experience proved to be a humbling initiation into the world of professional stunt work and physical endurance.
Recalling his first encounter with the WWE’s "Scottish Warrior," Drew McIntyre, Mattson notes the shock of reality. "I was told that Drew was a big guy, and I was like, ‘Okay cool, I’m a big guy,’ and then he came on set and this dude is a giant, man!" The 6’3" actor, who prides himself on his imposing frame, found himself suddenly dwarfed by the 6’5" McIntyre. Despite the physical disparity, the two formed a fast friendship, bonded by the intense demands of the production.
The Superhero Protocol: Nutrition and Training
Mattson’s preparation for Agent of Shadows was rooted in a rigid, "stay ready" philosophy. To maintain his current 215-pound frame—up from the 185-pound weight he carried during his earlier modeling career—Mattson treats his body like a high-performance machine.
The "Cindy" Method
Central to his fitness regimen is the "Cindy" workout, a high-intensity CrossFit circuit favored by Hollywood A-listers like Tom Holland for its efficiency in building functional, "superhero" muscle. The workout is deceptive in its simplicity:
- 5 Pull-ups
- 10 Push-ups
- 15 Air Squats
- Repeat for as many rounds as possible.
"I was like, that seems too easy, but the first time, I got to round eight, and I was gassed," Mattson admits. He has since scaled the challenge, hitting a personal peak of 16 rounds and incorporating 40-pound dumbbells into his squats to ensure progressive overload.
Nutritional Discipline
For Mattson, fitness is as much about the kitchen as it is about the gym. Balancing a career with the chaos of a household featuring four children and two dogs requires military-grade discipline. He consumes five meals a day, tracking his macros with precision.
His home life features a dedicated cupboard for his personal nutrition—a "no-go zone" for the sweet temptations that often plague a family household. By swapping refined sugars for blueberries (to aid muscle recovery) and choosing almonds over processed snacks, he keeps his physique in constant "camera-ready" condition. "I always stay ready, so I don’t have to get ready," he says, a motto that proves essential given the industry standard of receiving as little as 24 hours’ notice for a shirtless scene.
The Physicality of the Ring: Official Insights
The production of Agent of Shadows was not merely a stylized action sequence; it was a grueling physical endeavor. Filmed under the harsh, unrelenting heat of the desert, the shoot required Mattson to engage in legitimate stunt work alongside WWE Hall of Famers.
In one particularly taxing scene, Mattson went toe-to-toe with Booker T. "Physically, I was doing all the WWE stunts on the ground," he recalls. The result was not just a great take, but a body that felt the repercussions for days afterward. To better understand the craft of his co-stars, Mattson even enrolled at the WWE Performance Center. He didn’t just study the moves; he experienced the impact. Reflecting on taking a legitimate chair shot, he says, "It’s harder than it looks. It gives you a whole new level of respect for what these athletes do every single week."
The Future of Vertical Media
The implications of Mattson’s success are significant for the entertainment industry. As traditional streaming platforms—from Netflix to Disney+—begin to experiment with vertical content to capture younger demographics, the demand for actors who can bridge the gap between "social media influencer" and "legitimate action star" will skyrocket.
Mattson currently stands at the intersection of these worlds. He has successfully translated the aesthetic appeal of a model into the grit of a stunt-capable lead actor. While he remains tight-lipped about his upcoming "horizontal" projects, his trajectory suggests that he is moving toward more traditional feature-length narratives.
However, he remains a staunch proponent of the micro-drama format. He views it as the future of audience engagement, a space where the barrier between the creator and the viewer is thinner than ever. His experience with Agent of Shadows has proven that whether the screen is vertical or horizontal, the fundamental requirements of a leading man remain the same: discipline, adaptability, and the courage to take a chair shot for the sake of the story.
As the industry continues to shift, Mattson’s "stay ready" mantra serves as a blueprint for the modern performer. In an age of ephemeral content, he has proven that substance—built through thousands of hours of training and rigid nutritional compliance—is the only way to remain relevant in a world that is constantly scrolling to the next big thing.
Catch the action: Agent of Shadows is currently available for streaming on the ReelShort platform. For those looking to follow Chase Mattson’s ongoing training and career developments, his insights into fitness and acting can be found on his official Instagram channel.
