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.

Christian Lee has been a personal trainer since 2009 and also has over 7 years of experience using exercise and lifestyle-based interventions in the care and management of type 2 diabetes through the Special Diabetes Program for Indians. He holds certifications through the ISSA and the NSCA including the Certified Strength and Conditioning Coach certification. He holds Master's Degrees in both applied exercise science and fine art and is currently pursuing a PhD in kinesiology. He also holds black belts in taekwondo and hapkido and has competed internationally for Guam in taekwondo. He has also been competing in powerlifting for the last 13 years.

Christian is passionate about strength and conditioning as well as corrective exercise and fine-tuning individual movement mechanics. He believes that one's outlook and training philosophy takes precedence over the small details of a particular exercise program. Mindset is key to making a program successful. He also believes that one should try to appreciate the process along with being excited to reach their objectives. Happiness often lies in the process rather than just the other side of the goal.

Christian spent most of his time growing up on the South Pacific island of Guam. Since then, he has moved around the west coast residing in Washington, Nevada, and California. He is the father of two spunky kids and is very much a dog person. He enjoys strength training and nerdy stuff in general such as fantasy and sci-fi books and anime. Christian's favorite quote comes from a powerlifter named Scott Yard who said, "You do something that matters to no one else but yourself. It may be silly. It may be stupid. However, in that moment, it encompasses everything you want to be."

Growing up, Kristin swam competitively and played competitive softball. Her journey to strength and conditioning started when she decided to not pursue sports within college. Instead, she did strength and conditioning for a variety of collegiate athletes. This led her to specialize in sports performance and eventually acquire her NSCA Certified Strength and Conditioning Coach certificate.

After moving back to the Bay Area, she's worked with a variety of clients ranging from high school to over 80 years old. She's found that her background transfers well to functional fitness as she aligns work done in the gym to daily activities enjoyed by her clients. Her training style emphasizes learning because she wants her clients to understand why each exercise is important to them and their goals.

Beyond the gym, Kristin is currently pursuing her Master's in Exercise Physiology and in her free time enjoys exploring new places and activities. Her favorite activities currently revolve around the circus arts particularly those in the air and those with fire!

Jon is from San Jose, CA and has always considered himself an athlete. After playing soccer at West Valley College he began working at Stanford University as a personal trainer. Jon went on to pursue a Masters degree in Kinesiology, multiple certifications and now has over 7 years of experience. When it comes to his training philosophy, he likes taking a strength approach. In his experience, when clients focus on getting stronger and increasing muscle mass, other aspects of their fitness journey fall into place. Helping the general population find their confidence through this type of exercise is truly rewarding. Outside of the gym, he enjoys spending time with his wife and dog wherever that may be. He makes sure there’s always a travel vacation booked or being planned for the future.
