Custom Fit Becomes First Gym in the Nation to Offer Unlimited DEXA and VO₂ Max Testing to Its Members; Opening Fourth Location in San Francisco

Custom Fit, a San Francisco-based performance and longevity studio, is now the first gym in the United States to include unlimited DEXA scans and VO₂ Max testing in its core membership. This comes alongside the opening of its fourth location in Downtown San Francisco.

As demand for data-driven, personalized health continues to accelerate, Custom Fit is positioning itself at the intersection of fitness and clinical diagnostics by bringing services typically found in medical settings into a high-touch training environment.

“We do genetic testing, bloodwork, DEXA scans, VO₂ Max testing, gait analysis, fitness training, and nutrition coaching, all under one roof,” said Evan Mather, founder of Custom Fit. “Honestly, it’s what healthcare should be.”

Testing Is No Longer Optional

While still offered as standalone services, DEXA and VO₂ Max testing are now fully embedded into Custom Fit’s core membership model. This testing is a foundational component of training, recovery, and long-term health rather than an optional add-on.

By making DEXA and VO₂ Max testing universally accessible within their membership model, Custom Fit ensures that performance, recovery, and longevity strategies are guided by real, personalized data.

Custom Fit’s integrated training membership model includes:

• Unlimited DEXA scans to track changes in lean mass, fat mass, and regional body composition over time
• Unlimited VO₂ Max testing to assess cardiovascular fitness, aerobic efficiency, and longevity potential
• Unlimited group training classes to complement training options
• Unlimited access to recovery modalities, including infrared sauna and cold plunge therapy

Together, these services create a closed-loop system where training decisions and recovery strategies are continuously informed by objective, repeatable data.

A Model Shaped by a Data-Driven Market

Custom Fit’s model reflects the demands of a population that values measurable outcomes and continuous improvement. In San Francisco, a city shaped by technology and innovation, integrating advanced diagnostics into everyday training aligns with how high-performing individuals approach decision-making across all areas of life.

For operators, employers, and wellness leaders

As the fitness and wellness sector moves toward greater personalization and accountability, Custom Fit’s approach represents a shift toward measurement-driven membership experiences. By removing traditional barriers to testing, members track progress continuously rather than episodically, giving training decisions a real physiological foundation.

For operators, employers, and wellness leaders, the model offers a scalable framework that aligns performance, engagement, and long-term health outcomes within a single environment.
