That gaming room isn’t just a place for Fritz to decompress after grueling practice sessions, though; it’s another training ground. It might seem counterintuitive to the traditional image of an elite athlete, but recent studies, including a few that monitored adults playing Tetris, have shown that video games can actually be effective for managing stress and even mitigating the effects of psychological trauma. For Fritz, the digital arena is about more than just stress relief; it is a cognitive sharpening stone. “There’ve been other studies, as well, showing that the game I play specifically—League of Legends—improves a lot of focus and cognitive things,” he says of the arena-style competition where teams of players battle as fantastical characters in a high-stakes environment. “I’ve definitely noticed crossover: When I feel like my brain’s working well when I’m playing the game, my brain’s working well when I’m on the court.”
League of Legends, a Multiplayer Online Battle Arena (MOBA), requires immense spatial awareness, rapid decision-making, and the ability to track multiple moving variables simultaneously. In many ways, it is the digital equivalent of a 130-mph serve coming at your head. If you’re still dubious about the utility of a keyboard and mouse in professional athletics, Fritz has receipts. Take his run-up to the title at the 2023 Atlanta Open. “I was having such a good week playing in League, and my mind felt so turned on. It’s like playing chess with pieces that are almost moving without your control.” This flow state, often described by psychologists as "autotelic experience," is what every professional athlete chases. When the mental calculations happen subconsciously, the physical execution follows with a fluidity that is impossible to force.
Fritz didn’t drop a set en route to the final that week in Atlanta, then came out on top after a battle against Aleksandar Vukic. More than the results, though, he remembers the feeling: the sense that every calculation arrived a fraction of a second faster than usual. On the ATP Tour, where the difference between a winner and a forced error is measured in millimeters and milliseconds, that cognitive edge is everything. “How I was reading the mental side of things on the court, I just felt like it was so good. My decision-making and focus were elevated that week. My coach was like, ‘How were the games last night?’” Fritz recalls with a laugh. “I was like, ‘Good. I felt locked in.’”
While the mental game is cultivated in the glow of a monitor, the physical toll of the tour requires a much more grounded approach. Tennis is a sport of attrition, played across varying surfaces and climates, often demanding five-hour marathons in 100-degree heat. For Fritz, managing this physical stress recently required a radical transformation. Dealing with chronic tendonitis and a nagging knee injury earlier this season, Fritz realized that his "playing weight" needed to change. On the advice of his team and following discussions on platforms like Andy Roddick’s podcast, Fritz committed to dropping weight to alleviate the load on his joints.
He ultimately lost 15 pounds, a significant shift for a man who stands 6’5" and weighs approximately 200 pounds. “Getting older, it’s not as easy for me to just eat what I want to eat and stay super skinny,” Fritz admits. The knee injury created a vicious cycle: the pain prevented him from training at full intensity, which meant he was burning fewer calories, but his eating habits remained those of a high-performance athlete. To break the cycle, he utilized a two-month injury hiatus to overhaul his routine. “If I just drop 10, 15 pounds, it’s going to take a little bit of load off of the knee. And also just, why not? Why not just lean out and do it in a way where I’m not losing muscle?”
His approach was a masterclass in disciplined bio-hacking. He calculated his Basal Metabolic Rate (BMR) at approximately 2,000 calories and aimed for a consistent daily deficit of 1,000 to 1,200 calories. This is an aggressive cut for an elite athlete, but Fritz balanced it with a massive intake of protein—matching his body weight in grams. “Getting 200 grams of protein in a day is not easy. It’s something that you really have to actually take time to think about and strategize,” he explains. By maintaining high protein levels, he ensured that the weight lost was fat rather than the lean muscle mass required for his explosive power on the court. Remarkably, his strength metrics in the gym actually increased during the weight loss period, proving that his "healthy way" of leaning out was successful.
Consistency is the cornerstone of Fritz’s wellness philosophy. He eschews "splashy new things" in favor of routines that work. This includes a surprising staple of his diet: Chipotle. “I was pretty much eating Chipotle every single day after my practice,” he says. It provided a predictable, high-protein, controllable meal that fit his macros perfectly. His specific order—double chicken, light rice, no beans, fajita veggies, and very light sour cream and cheese—allowed him to fuel his recovery without blowing his calorie budget.
Beyond nutrition, Fritz has embraced the data revolution in sports recovery. He is a staunch advocate for the Eight Sleep system, a high-tech mattress cover that regulates temperature and tracks sleep metrics. “It really wins you over with it making adjustments in the night… it tells you all your sleep score stuff,” he says. For an athlete who travels across time zones and often finishes matches at 2 a.m., sleep hygiene is not a luxury; it is a performance requirement. Fritz has mastered the art of the "body clock shift," adjusting his sleep schedule days in advance of night matches so that he is peaking at 8 p.m. rather than winding down.
However, the integration of wearable technology on the court remains a hurdle. While Fritz utilizes heart rate monitors and calorie trackers during training, the ATP’s regulations on wearables during matches are still evolving. “On the men’s side, the only thing that’s actually approved is one of those Catapult sports bra-type things,” Fritz notes. In the sweltering humidity of the US Open or the Australian Open, wearing an extra layer of fabric is often a non-starter. He looks forward to a future where discreet sensors—perhaps integrated into wristbands or straps—are permitted, allowing coaches to monitor live biometric data during the heat of battle.
Hydration is another area where Fritz has moved from casual to clinical. In the past, he would rely on whatever the tournament provided, such as Gatorade or Powerade. Today, his strategy is much more sophisticated, focusing on the 24 hours leading up to a match. “The 24 hours of hydration before you actually play is a big part of it, just having the electrolytes, having the water as well,” he explains. He has adopted the use of SILA tablets, a formula specifically designed for Novak Djokovic. The logic is simple: if the most physically dominant player in the history of the sport uses it, it is likely the gold standard. These tablets provide the high levels of sodium and electrolytes necessary to replace what is lost through the heavy sweating inherent to elite tennis.
To round out his regimen, Fritz maintains a targeted supplement stack designed for both physical longevity and mental clarity. Collagen is a non-negotiable for his tendon health, providing the building blocks for his joints to withstand the jarring stops and starts of hard-court tennis. He also takes Creatine, a supplement traditionally associated with bodybuilders but increasingly recognized for its neuroprotective and cognitive-enhancing properties. “There’s so much research on the cognitive benefits of it, not just the fact that it’s going to help you put on muscle,” Fritz says. Vitamin D and Omega-3 fish oils complete his daily routine, addressing common deficiencies and reducing systemic inflammation.
Taylor Fritz’s "Routine Excellence" is a testament to the modern professional athlete’s multifaceted approach to the game. It is no longer enough to just hit a thousand backhands a day. To compete at the highest level of the ATP Tour, one must be a nutritionist, a sleep scientist, a data analyst, and, apparently, a high-level League of Legends player. By blending the digital and the physical, the high-tech and the disciplined, Fritz is not just playing the game—he is optimizing every second of his life to ensure that when the moment comes to be "The Guy," he is ready. Whether he is staring down a break point or a digital raid, Fritz is "locked in," proving that excellence is not an act, but a meticulously maintained routine.
