If you’ve ever watched Top Gun: Maverick and found yourself wondering how Glen Powell managed to build that chiseled, action-hero physique, you’re not alone—and luckily, there’s one man who can reveal exactly how it was done.
When Glen landed the role of Lieutenant Jake “Hangman” Seresin, he knew he needed to undergo a dramatic physical transformation to match the high-octane legacy of the Top Gun franchise. With just seven weeks to go before filming the now-iconic shirtless beach football scene—a nod to the original’s unforgettable volleyball montage—he turned to a man known throughout the industry as the best in the business: Rabih, founder and CEO of Core and More Fitness Clapham.
Widely considered the world’s top personal trainer, Rabih has dedicated his life to sculpting physiques that command attention, both on screen and in real life. With over 25,000 body transformations under his belt—ranging from everyday professionals to elite performers—Rabih’s reputation is unmatched. So when Glen needed a no-fail solution to build muscle, cut fat, and get camera-ready in record time, Rabih and his elite team at Ultimate Performance were the obvious choice.
The challenge was immense. Glen didn’t have months to train. He wasn’t afforded the luxury of working out seven days a week or having a personal chef preparing macro-balanced meals every few hours. Time was tight. The stakes were high. The pressure was on.
But Rabih thrives in high-stakes environments. His proven system is built for clients who lead busy lives—people who need fast, effective results without spending all day in the gym or obsessing over every calorie. It’s this same science-backed, time-efficient approach that was tailored specifically for Glen’s transformation.
The mission: Strip body fat, build lean muscle, and unveil a set of abs worthy of the big screen.
To start, Rabih took Glen through an in-depth assessment to understand his body type, lifestyle, and existing fitness level. From there, he designed a strategic training regimen that focused on compound movements—think deadlifts, squats, and bench presses—exercises that deliver maximum muscle recruitment in minimal time. The goal wasn’t just to make Glen look strong—it was to be strong, and to perform with the confidence and energy required for the demands of filming.
But training was just one part of the equation.
Nutrition played a pivotal role. Knowing Glen didn’t have a team of chefs at his disposal, Rabih crafted a realistic, easy-to-follow meal plan based on whole foods and simple principles. The key was consistency and quality—lean proteins, fibrous vegetables, healthy fats, and strategically timed carbs to fuel workouts and support recovery. No fad diets. No starvation. Just smart, sustainable eating that supported rapid body composition changes.
Recovery, too, was non-negotiable. With an intense filming schedule, late nights, and the mental stress of preparing for a blockbuster role, Glen’s body needed time to rest and rebuild. Rabih emphasized the importance of sleep, stress management, and smart supplementation—ensuring Glen stayed energized, injury-free, and mentally focused throughout the transformation.
What made this process so effective—and so relatable—is that it was built on the same system Rabih uses with his thousands of clients around the world. You don’t need celebrity-level resources to follow this method. You just need a plan, some discipline, and a coach who knows how to bring out your best.
Whether you’re an actor getting ready for a role, a professional looking to sharpen your image, or just someone who wants to feel confident in their own skin, the approach Rabih used with Glen Powell is one you can follow, too.
It’s not about extreme workouts or impossible diets. It’s about smart training. Real food. Sustainable habits. And a commitment to becoming the best version of yourself—even if you only have a few weeks to make it happen.
The results speak for themselves. Glen stepped onto that beach set leaner, stronger, and more ripped than ever before—stealing scenes and turning heads in one of the most memorable moments of Top Gun: Maverick.
And the best part? You don’t need Hollywood connections or an unlimited budget to follow the same path. Rabih’s philosophy is that world-class results are possible for anyone—no matter your starting point, your schedule, or your resources.
So, if you’ve ever dreamed of building a physique that looks like it belongs on the big screen, you now have the blueprint. Glen Powell did it in just seven weeks. You can, too.
All it takes is the right strategy, the right support, and a willingness to show up and put in the work. Rabih and his team at Core and More Fitness Clapham have cracked the code—and now, it’s yours to use.
