The Science Behind Peak Performance: How a Neuroscientist and Engineer Are Revolutionizing Health for STEM Professionals

What happens when cutting-edge neuroscience meets precision engineering in the pursuit of human optimization? You get a revolutionary approach to health that's changing how high-performers think about their bodies and brains.

In this powerful episode, Dr. Lola Adeyemo chats with Dr. Gina D'Andrea-Penna and Gil Acevedo, co-founders of Nexus Fitness, who are bringing scientific rigor to the fitness industry. Their unique backgrounds—shaped by neurodiversity, immigration, health challenges, and athletic transformation—have led them to create a holistic coaching platform specifically designed for STEM professionals who demand evidence-based solutions.

About Our Guests

Gina D'Andrea-Penna is a neuroscientist and fitness coach who co-founded Nexus Fitness. During her PhD, she studied how health and lifestyle choices shape the brain, uncovering the powerful, cumulative impact of our daily habits on how we think, feel, and show up in the world. That research—alongside her own health and fitness journey—inspired her to launch a coaching business with her husband, Gil. Gina is passionate about helping others live more intentional, meaningful, and fulfilling lives, and she believes fitness is the foundation for doing exactly that.

Gil Acevedo is a Staff Software Engineer at Qualcomm and the co-founder of Nexus Fitness. With a background in Computer Science and a lifelong drive to grow stronger—physically, mentally, and professionally—Gil brings both technical precision and grit to everything he does. He's passionate about fitness, building tools that help people thrive, and creating impact through entrepreneurship. Whether he's writing code, lifting weights, or helping build a business alongside his wife, Gina, Gil is fueled by curiosity, discipline, and a vision for what's possible.

The Intersectional Lens That Drives Innovation

Gina's Multifaceted Perspective

Growing up with an older sister with Down syndrome, Gina became a Special Olympics volunteer and unified partner, exposing her to the incredible resilience of people with disabilities. Her childhood was further shaped by her mother's work teaching ESL and her father's position at Gallaudet University, creating a household rich with diverse perspectives and cultures.

The intersection of being a young woman with celiac disease proved particularly formative. When doctors dismissed her symptoms as an eating disorder, she learned a crucial lesson: "Just because somebody's a medical professional doesn't mean they know what's best for you—you know your body the best." This experience would later inform her approach to personalized health coaching.

Gil's Journey of Transformation

As a Mexican-American who immigrated back to the US at age 13, Gil understands the challenge of starting over in a new culture while maintaining cultural identity. His athletic career in track and cross-country came to an abrupt end with a permanent hamstring avulsion injury in high school—a setback that became a setup for discovering strength training and personal development.

Growing up in an immigrant household where his parents took demanding labor jobs that eventually harmed their health, Gil witnessed firsthand the cost of neglecting wellness. "When you don't have your health, that's all you want," he reflects, explaining the driving force behind his commitment to helping others prioritize their wellbeing.

From Personal Struggles to Scientific Solutions

Both founders experienced pivotal moments where personal health challenges became catalysts for helping others at scale. Gina's transition from long-distance running (and the injuries that ended that chapter) to strength training paralleled her academic shift from studying consciousness to investigating how daily habits shape brain function.

Gil's evolution from a shy teenager affected by bullying to a confident engineer demonstrates the transformative power of physical fitness: "Once I went to the gym and saw my body transforming, that enabled me to feel more confident—and that translates to showing up in the workplace, feeling confident to speak up and share your ideas."

The Neuroscience of Peak Performance

What sets Nexus Fitness apart is their evidence-based understanding of the mind-body connection. As Gina explains from her research: "Your physical health and your day-to-day choices fundamentally shape how the brain works. You are not going to perform at your best at work if one of these pieces is falling apart."

Their holistic approach recognizes that true optimization requires attention to:

  • Physical Activity: Movement patterns that enhance rather than deplete cognitive resources
  • Nutrition: Fuel strategies customized to individual needs and cultural preferences
  • Sleep Quality: The foundation of memory consolidation and decision-making
  • Stress Management: Tools for maintaining performance under pressure
  • Education: Understanding the science behind sustainable behavior change

Essential Wisdom for High-Performing Professionals

On Breaking Cultural Barriers to Wellness

Gil addresses a common challenge in immigrant communities: "Growing up, we don't think about going to the gym if there's nothing wrong with you that the doctor asks you to work on. We see our parents work and work and work—there's no time for preventative care."

On The Modern Health Paradox

Gina highlights a critical insight: "The modern world has created an environment where it's so easy to make the unhealthy choice. We go for the path of least resistance, but we've created a situation where the path of least resistance is actually ruining our health in the long run."

On Confidence Through Physical Transformation

Both founders emphasize how physical strength translates to professional confidence. Gil shares: "Everything is connected—work on yourself more than you work on anything else. How you show up physically affects how you perform mentally and professionally."

On Customization Over Trends

Their approach prioritizes individual needs over popular fitness trends: "Everyone is different—what works for one person may not work for another. You need to study your body and understand how you respond to different approaches."

The Science of Sustainable Change

Drawing from Gina's neuroscience background and Gil's engineering precision, Nexus Fitness focuses on creating systems that work within the constraints of demanding careers. They understand that STEM professionals need evidence-based approaches that fit into packed schedules and high-stress environments.

Their coaching methodology combines behavioral science with practical implementation, recognizing that knowledge without application is worthless. As Gil puts it: "The meaning you bring to things is what makes them powerful—whether it's your work, your health habits, or how you interact with the world."
