Personal Trainer

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.

Christian Lee
Personal Trainer
Contact
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."
What I love about FiT: The supportive energy and environment. The staff is legitimately there to help when it comes to just about anything. It helps that they are all extremely capable as well. Another thing that I love about FiT is its approach. FiT's philosophy centers on more than just exercise and nutrition. It focuses on an all-around emphasis on health and well-being that include sleep and stress management strategies.
Nick Weigel
Physical Therapist

Nick graduated from The Ohio State University in 2010 with a degree in English. His focus at that time was to continue rowing competitively, which brought him to the Boston area. There he completed his Doctorate of Physical Therapy from Massachusetts General Hospital Institute of Health Professions in 2018.
In Boston Nick worked at a clinic well known for treating professional runners and other endurance athletes. He enjoyed working with high schoolers and their parents the most. It was here he developed a passion for treating tendinopathy. Having had his own experience with a high hamstring tendinopathy he found it helpful to be able to empathize with others going through this uniquely frustrating condition. It also was here that Nick first started to learn about bike fitting and he has since gone on to obtain his Level 1 International Bike Fit Institute certification.
Nick has enjoyed being a competitive endurance athlete for 17 years. He has gone from world championship trials as a rower, running 5ks to half marathons to ultra trail runs in the White Mountains, to racing UCI cyclocross as a category 2 cyclist. Nick no longer races competitively due to a heart condition but you can now find him olympic weightlifting, mountain biking or gravel riding, taking photos of bike races, or hiking with his wife and 2 dogs.
Nick enjoys taking an active treatment approach with an emphasis on play and variability, he believes movement is the best medicine, and often complex problems have simple solutions.
Kristin Pampeyan
Trainer

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!
What I love about FiT: That everyone is invested in the community whether it's by hosting additional activities or sharing knowledge. It's all to make each other better and help out the clients.

Dae-Von Bishop
Personal Trainer
Contact
All the way from East Palo Alto, Dae-Von was an avid basketball player and fan since the age of 10. From Eastside College Prep to Sonoma State to Foothill where he received his AA in psychology. Dae-Von developed a passion for training and helping others stay active and healthy after a bad ankle sprain in high school that occurred during the basketball season. Dae-Von received training the following summer at The Riekes Center, leading him to have a healthy senior year season as well as making 2nd team all league.This is what inspired him to become a trainer and help other athletes stay in great shape. At 20 years old, Dae-Von’s personal training journey began at The Riekes Center, and he hasn’t looked back since.
Dae-Von holds certifications in personal training through NASM, archery, as well as speed and agility and weightlifting both through NSPA. He even will do some basketball skill development on the side for young hoopers. His goal is to help people stay as fit and active as possible with little to no complications. I love training groups of athletes in either middle or high school. Those age groups tend to be the best time for athletes to get faster and stronger, as well as they begin to understand movement patterns which allow them to perform at an elite level. There is also a natural competitive aspect of training in groups that pushes kids to go harder during drills.
In his free time, you can find Dae-Von shooting hoops, working out, playing video games, spending time with friends, trying new foods(as long as there is no avocado), or hanging out with his frenchie, Trouble.
What I love about FiT: The embodiment of teamwork that is displayed on a regular basis, as well as the encouragement to constantly get better as trainers.
Favorite sport: Basketball and Football

FiT's philosophy around the 5 tenets of optimal health aligns well with my beliefs surrounding how best to care for my clients and myself. When clients subscribe to FiT's services, they are signing up for a training program that includes learning about how to live better for longer. Who wouldn't love that?

While studying biological sciences at Cal Poly SLO, it became clear that my health was suffering. I was always tired, I couldn’t sleep well, I had digestive issues, and my emotions would swing dramatically at times. The realization came that in order for me to enjoy life to its fullest, I had to get serious about improving the quality of my health.
Since then, I’ve studied with doctors, physical therapists, clinical nutritionists, physical trainers, bodyworkers, and top innovators in the field of health & wellness. Instead of chasing the symptoms of illness, the most effective approaches to well-being are those that work to eliminate things that degrade health AND instill lifestyle habits that allow the natural environment of our bodies and mind to operate as efficiently as possible. In this way, we can be lead lives with less pain & sickness.
My work aims to use the technology of the body to help you live a more vibrant & productive life.
Some of the things I have fun doing are Olympic Weightlifting, breakdancing, parkour & free-running, snowboarding, creating electronic music, digital art photography/ videography, competing in American Ninja Warrior (My competition run is here) & learning about quantum physics.
What I love about FiT: Uplifting, motivating, supportive
