San Francisco Gym Experience: Best Luxury Fitness at Custom Fit.

Finding a high-end, exclusive gym in San Francisco that delivers personalized, scientifically-backed results can be a challenge. You need more than just a room with equipment; you need a supportive environment that guides your goals with expert advice and a clear plan. Custom Fit offers a solution, blending a luxury setting with a data-driven method to wellness. We are more than just a gym—we provide a comprehensive wellness experience designed to help you understand your body and achieve measurable outcomes.
What Makes Custom Fit a Premium Fitness Facility in San Francisco?
A premium fitness experience is defined by its atmosphere, the quality of its facilities, and how complete its services are. It’s a space where every detail is chosen to support your health and performance with a structured, thoughtful process. At Custom Fit, we excel in all these areas, setting a new standard for those seeking a premium fitness facility in San Francisco.
A Private and Uncrowded Atmosphere
We intentionally limit our memberships to ensure a private, professional, and uncrowded environment. This controlled setting means you won't be waiting for equipment, allowing you to focus entirely on your workout. Unlike large commercial gyms that can feel chaotic, our space is designed for focus. Members appreciate the consistently available equipment, with one client praising the "clean, friendly, and non-crowded" atmosphere [1].
State-of-the-Art Facilities and Equipment
Our expansive 8,000 sq. ft. space is spread across three versatile studios, providing you with everything you need for effective training. You will have access to top-of-the-line equipment, including:
- 8 Rogue squat racks
- Woodway treadmills, Concept 2 rowers, and Rogue assault bikes
- A wide variety of functional training tools and specialty bars
To enhance your experience, we provide luxury amenities such as private bathrooms and showers, full towel service, and premium Aesop products. You can explore our meticulously designed facilities.
Integrated Wellness: More Than Just a Workout
Our philosophy is a holistic system built on four pillars: Train, Test, Nourish, and Recover. This integrated approach ensures all factors impacting your health are addressed. We offer unique amenities designed to optimize recovery and performance, including a dedicated Recovery Room with a private infrared sauna and cold plunge. This comprehensive approach, which includes nutrition coaching with Registered Dietitians, has helped establish Custom Fit as one of the city's best gyms [2].
A Data-Driven Approach for Measurable Results
We use science and technology to move beyond guesswork and deliver personalized, effective fitness plans. This methodical approach is key to making sure your effort is directed efficiently, leading to real, quantifiable, and sustainable results.
Longevity Testing for Personalized Insights
Advanced testing is the foundation of creating a truly custom program. In our Longevity Testing Lab, we use diagnostic tools to gather baseline data on your unique body. Available tests include:
- DEXA Scans (the gold standard for body composition)
- VO2 Max & RMR Testing (to measure metabolic and cardiovascular performance)
- 3D Gait Analysis
- Advanced Bloodwork
A complimentary DEXA scan is included with every membership, providing a crucial dataset to accurately track changes in your body composition over time.
Expert Personal Training Tailored to You
Our personal training programs are designed for you, not the masses, based on your specific goals, lifestyle, and the data we collect. Our team of certified, expert trainers acts as your guide, providing the accountability and technical oversight needed to ensure proper form—a critical factor for both safety and effectiveness. This personalized model is suitable for all levels, from beginners establishing a new routine to advanced athletes refining their performance.

How Custom Fit Stands Out from Other SF Gyms
Custom Fit offers a unique experience in the San Francisco fitness market, which is reflected in our client feedback and a 4.9-star rating based on 138 reviews [3]. Unlike the bustling environment of large chain clubs like Equinox [4], we offer a private, controlled experience. While specialized studios such as Eden Fitness [5] focus on a single service, our model integrates training, data-driven testing, nutrition, and recovery all under one roof.
