When Julius Thomas hung up his NFL cleats in 2018, he had no idea he was about to step onto the playing field for the hardest and longest transition of his life. The former tight end, who once caught pinpoint touchdowns from legendary quarterback Peyton Manning, suddenly found himself walking into graduate school at the age of 30. He was stripped of his playbook, devoid of a corporate title, and cut off from the immediate, daily dopamine hits of victory that professional football used to hand him on a weekly basis.
Reflecting on those early, humbling days in academia, Thomas recalls the jarring shift in identity and capability. When an elite athlete transitions into a completely unfamiliar field, the psychological impact can be profound.
"When you have to go from a master to a rookie, you go from winning a lot, knowing what you’re doing and very comfortable with all of it, to then having to rebuild that," Thomas recalled. "That is extremely challenging, because in the beginning of any journey, it’s losing, doing it wrong, working really hard, struggling through it."
The arduous lessons he learned over the years that followed fundamentally changed the way he looked at human performance. Rather than shrinking from the discomfort of starting over, he threw himself back into the classroom, completed a rigorous clinical residency, and ultimately earned his doctorate in clinical psychology in June 2025.
In the high-stakes world of professional sports, the cultural mentality is almost universally built on pushing through pain, ignoring fatigue, and keeping going at all costs. While Thomas lived and breathed that philosophy for years on the gridiron, today his perspective is entirely different. As a performance coach and consultant with his company, Optimal Performance System, he now sees that true peak performance relies heavily on doing the exact opposite: stepping back, slowing down, and regularly checking in with ourselves.
"One of the things I say is the biggest unaddressed area of performance in all of sport is emotional regulation," Thomas told Muscle & Fitness.
Thomas’ Take on NFL Injuries This Season
The 2026 professional football season has already severely tested the traditional push-through mindset from its earliest opening weeks. Six of the 32 quarterbacks initially named as primary starters were forced out of action early in the campaign, including standout young talents like Jayden Daniels, Caleb Williams, and Jaxson Dart. Meanwhile, Philadelphia Eagles star quarterback Jalen Hurts faced an even more alarming medical crisis, expected to miss the remainder of the season after doctors discovered deep vein thrombosis and bilateral pulmonary emboli—a terrifying condition traced back to an initial calf injury caused by an opponent’s cleat.
When asked about the alarming run of injuries across the league, Thomas resisted pinning the trend on any single isolated cause, nor did he view the current wave as entirely anomalous.
"Football has a 100% injury rate," he says. "Every single person that plays football is going to get injured, so injuries are just high in that sport in general."
Contact injuries are simply an unavoidable cost of doing business in a violent, collision-based sport, he noted. However, training loads, playing surfaces, off-season habits, mobility work, and proper recovery—or the chronic lack thereof—heavily dictate the occurrence of non-contact injuries. Furthermore, modern scientific research has consistently shown that the human mind plays a definitive role in physical resilience and vulnerability.
A prominent 2017 meta-analysis published in Sports Medicine linked acute and chronic stress responses directly to higher injury risk, while demonstrating that targeted psychological interventions can successfully reduce overall injury rates. Because of these interconnected systems, Thomas makes it a priority to advocate for taking our collective foot off the accelerator far more frequently than modern high achievers are accustomed to doing.
"If you just only floor it, only floor it, only floor it, how long do you think that engine is going to do well?" Thomas explains. "Not very long."
In physiological terms, those much-needed breaks represent the parasympathetic nervous system—the critical "rest-and-digest" branch that directly counters the body’s acute stress response.
"If we don’t do enough to create more parasympathetic tone in our nervous system, if we don’t sleep enough hours, all we’re doing is degrading the major systems in our body," he explained, noting that the biological cost of the relentless grind will inevitably come due sooner or later.
How Every High Performer Pays the Tab
This relentless behavioral pattern does not stay confined to the locker room; it invariably follows ambitious high performers straight into the corporate boardroom. Thomas has worked with executive clients who approached him searching for specialized nootropics to sharpen their cognitive focus, only to later confess that Thomas himself had maintained a punishing habit of getting just four hours of sleep a night for two decades during his playing days.
To combat this widespread cultural exhaustion, he has built a comprehensive framework called "Striving for 100" to gently guide clients back toward five foundational daily habits: exercise, sleep, nutrition, recovery, and healthy substance use, with adequate recovery deliberately anchoring all the rest. In one-on-one coaching sessions, he layers in radical acceptance, cognitive restructuring, and psychological reframing drawn from a variety of evidence-based methods, including cognitive behavioral therapy (CBT) and acceptance and commitment therapy (ACT).
"You’re either gonna pay the cost slowly and surely by recovering in your 30s and 40s and 50s," he says, "or you’re gonna pay it all of a sudden when you’re sick."
He holds himself strictly to that exact same standard of self-awareness and recovery. When a trusted friend once warned him that a full psychological and professional transition out of sports would realistically take about a full decade, Thomas initially refused to believe it.
"I am eight years in transition. And I’m almost to where I want to be in my next profession," he admitted. He quickly pointed out the deep difficulties he has personally experienced regarding personal identity, and how fundamentally misguided modern societal advice tends to be.
Thomas openly bristles at the standard advice athletes frequently receive on their way out of professional sports—the well-meaning platitude that they simply need to separate who they are as a person from the sport they played.
"It really bothers me when people say that about athletes, because they’re trying to minimize the challenge of the experience, so that when the athlete finds himself in the psychological challenge, they feel like they shouldn’t be, and this should be easy," he explained. He added that a human being’s identity runs far deeper than a simple occupational label; it is built steadily by what a person does every day and continuously reinforced by how the outside world perceives them.
Years after playing his final professional game, people still inevitably want to talk to him about his glory days in the NFL, where the two-time Pro Bowl tight end notably caught 12 touchdown passes in both the 2012 and 2013 seasons.
"It’s hard to get people to see you in your new career," he admitted candidly.
Now, part of his professional mission is preparing current and former athletes for that exact seismic shift. He challenges them to ask themselves whether they are truly ready for one of the most difficult psychological battles they will ever face, and whether they have actively built the internal tools necessary to survive it.
"Do you have the psychological skills to reframe, recontextualize, find meaning, find purpose?" he asks prospective clients.
Above all, what he does not want any player or high achiever to forget is that personal struggle says nothing negative about their character. Every major, life-altering transition places immense strain on the human psyche.
"Transitions are always hard," he said. But with the right psychological tools, professional guidance, and community support, navigating those turbulent waters becomes progressively easier over time.
When the Pain Doesn’t Show on an X-Ray
Most individuals are never taught to properly identify and name what they are feeling emotionally, let alone work through it when chronic stress drags on silently for months or even years. Thomas was no exception to this cultural blind spot during his football career, and he has witnessed firsthand the heavy toll that unmanaged psychological strain can take on the physical body.
"Emotions trigger our nervous system," he says, drawing directly from his advanced studies in psychoneuroimmunology. "So the better you get at managing emotions and reducing negative emotions, the less sustained stress you’d have on your nervous system."
This physiological connection matters deeply because our nervous system, immune system, and overall psychological state are inextricably linked, he notes. When emotional stress becomes chronic, various vital aspects of a person’s life begin to suffer. Sleep quality and nutritional habits are typically the first pillars to slip when emotional strain builds, while physical muscle tension climbs steadily as underlying anxiety lingers.
However, research shows that simply putting a complex feeling into words can help turn down the biological volume of stress. A landmark 2007 brain imaging study conducted at UCLA and published in Psychological Science demonstrated that the simple act of labeling negative emotions measurably dampened the amygdala’s stress response to negative visual stimuli.
Despite the proven power of emotional processing, very few people receive adequate support in doing that foundational work. Thomas cited data from the Centers for Disease Control and Prevention reporting that roughly 10.9% of U.S. men receive counseling or therapy from a mental health professional, compared with 16.9% of women. Furthermore, Thomas has observed stark contradictions in where modern consumers routinely choose to spend their hard-earned time and financial resources.
"People are not interested in paying for mental health services, but they’re really interested in new pants and new shirts and nice bags," he said. He highlighted the glaring double standard of how much easier it is for many people to ask for professional help with physical pain or visible bodily discomfort. As an active player, he never hesitated for a single second to walk into the team training room to address a sore ankle.
"We are constantly asking for help in so many areas of our life," he says, "but we somehow, as a culture, believe that we should handle what’s in our heart and in our mind by ourselves."
Meet Thomas at Eudaimonia
Today, Thomas is undeniably established in his new professional chapter, a reality reflected by the high-caliber peers and industry leaders he surrounds himself with. At the upcoming Eudaimonia event running from November 5 to 8, he is slated to share the stage with some of the most influential innovators across the modern health, wellness, and longevity industries.
Recalling his inaugural year attending the event, Thomas emphasized how deeply the professional relationships he built across the fields of psychology, neuroscience, medicine, and mind-body practices have continued to resonate in his daily life.
"The conversations, the network, the community I built at year one at Eudaimonia is still having positive influence on my life almost one year later," he said. "And Eudaimonia has become one of the conferences that I’m most excited to go to."
Thomas is returning to the event this year to deliver keynote presentations centered on mental health, alongside participation in a panel discussion exploring mindset, physical performance, and the innate human capacity to adapt under pressure. The primary takeaway he hopes audiences will walk away with is a renewed sense of practical hope, actionable steps, and educational insights designed to make individuals healthier, more productive, and operating at a higher level of daily functioning.
"If you want sustainable high performance, you have to build well-being and quality of life into what you do," he concluded.
