What fuels your passion for health and fitness?

Fitness saved me. After being diagnosed with OCD and anxiety in high school, weight training became my outlet and my anchor. Training gave me structure, focus, and mental resilience when my thoughts felt overwhelming. Over time, fitness grew from a coping mechanism into a passion, pushing me to compete in a Spartan race and challenge myself through endurance sports. Today, I train to grow stronger physically and mentally while inspiring others facing similar struggles.

What’s your favorite way to train or stay fit?

Weight training is my foundation. It is where I find focus, discipline, and clarity. I love structured lifting paired with purposeful movement like running, hiking, and functional training. Whether I am under a barbell or on a mountain trail, training keeps me present, grounded, and constantly progressing. It is not just about aesthetics. It is about building a resilient body and mind that can handle life’s challenges.

What would you do with $20,000?

I would invest it in my future as both a scientist and fitness advocate. As I complete my PhD in Materials Science and Engineering, I would use the funds to reduce financial stress, support my education, and expand my platform by creating content that connects science, mental health, and fitness. My goal is to empower others to build stronger bodies and healthier minds through education, discipline, and sustainable habits.
