Editorial Summary

Why They Stand Out

"Custom Fit in San Francisco offers premium personal training with a focus on individualized programming. The facility boasts top-tier equipment and a team of certified trainers with diverse specializations, including corrective exercise and performance enhancement. Their evidence-based approach emphasizes biomechanics and progressive overload. Their integration of physiotherapy principles with strength coaching delivers tailored, safe, and effective training for a broad clientele."

Community Feedback

"I've been training with James Coca for about a year now and it's been amazing! I came in with a little bit of experience but not much and he was super attentive and helped me to progress exactly like I was hoping to. Very friendly and knowledgeable, exactly what I was looking for in a trainer! The gym itself is also very nice, great equipment, super clean, and never overly crowded. Highly recommend for anyone who's been training before or just starting out like me!"

"The gym as a whole meh and left me wanting more but there was one thing...or person...that kept me coming back... James Cho was INCREDIBLE to work with. He was thoughtful in his approach and very professional throughout our time working together, both of which are high on my priority with working with a trainer or coach of any kind. I had three goals coming in: 1) Get comfortable strength training again, 2) improve mobility, 3) increase lean muscle mass. He helped with all three. I'm down 17 pounds, I'm sprinting again largely due to improved mobility, my energy has improved tremendously, and according to Oura I've turned back the clock on my cardiovascular capacity by three years. While I can't exclusively attribute this to my work with James, his training has played a meaningful role. I would work with him again and highly highly high recommend."

"I’ve been training with James Coca for over a year, and it’s been a great experience. He designs workouts based on my goals and adjusts them to accommodate my bad back and plantar fasciitis. When I travel, he provides a workout plan to keep me on track. He’s consistent, knowledgeable, and easy to work with. Thanks to his training, I’ve been able to start playing basketball again. Custom Fit’s facilities are always clean and well-organized. The equipment is in good condition, and the space is well-maintained. I also use the Custom Fit recovery room, which has been a great addition to my routine. If you’re looking for a trainer who listens and adapts to your needs, I recommend James Coca."
