Kira Vargas

Kira brings a unique perspective to fitness coaching, combining her engineering background with a passion for movement and community. A graduate of Carnegie Mellon University with a B.S. in Materials Science Engineering, Kira spent five years in the tech industry before pivoting to fitness. Over the past four years, she has honed her coaching skills at a CrossFit gym in South San Jose, specializing in group classes, Olympic weightlifting, powerlifting, gymnastics, and functional fitness. Her clients range from young adults to seasoned athletes in their 80s.

Kira’s own journey in fitness has been transformative—she’s lost 25 pounds since starting CrossFit and gained a deep appreciation for how consistency and patience unlock personal potential. In an age of instant gratification, she advocates for small, consistent steps, helping her clients build strength, resilience, and self-respect. Her philosophy is simple: show up, work hard, and anything is possible.

When she’s not coaching or training, Kira enjoys competing in CrossFit, exploring new sports, experimenting with ice baths, and indulging in great food.

What I love about FiT: FiT is more than a gym, it’s a place where you can transform your entire life. The leaders and staff here have their heart in the work, and truly care about creating positive change in the lives of our members.
