Personal Training with Unlimited DEXA and VO2 Max

Custom Fit

Most training programs run on guesswork. Custom Fit replaces it with measurement. At its San Francisco studios, Personal Training and Partner Training memberships include unlimited DEXA body-composition scans and VO2 max testing — diagnostics usually sold one scan at a time or reserved for specialized clinics. Custom Fit members can test as often as they train. The reasoning is straightforward. A DEXA scan measures fat, lean muscle, and bone density with clinical precision. A VO2 max test measures the body's maximum oxygen uptake, one of the strongest predictors of cardiovascular fitness and long-term health. Run those tests on a regular cadence and a member can see exactly what is changing, where, and whether a program is working — rather than relying on the scale or the mirror. That is the idea behind Custom Fit's positioning: not a gym, a performance lab. Every program is built from a member's measured body composition and cardiovascular capacity, then adjusted as the data moves. The goal is to eliminate the guesswork that defines most fitness routines and to treat training as something you can verify. The model also brings longevity diagnostics that usually live in concierge medicine into a routine training week. Body composition and cardiovascular capacity are central markers of how well a person is aging, and regular testing keeps those numbers visible rather than treating them as an occasional, expensive add-on. Custom Fit operates in Hayes Valley (323 Octavia Street), on Market Street (1844 Market), and with a Downtown San Francisco location on Battery Street (570 Battery) opening soon. Personal Training, Partner Training, and select memberships include the testing. More information is available at customfitsf.com.
