Personal Trainer Near Me in Hayes Valley: Custom Fit San Francisco
Custom Fit runs personal training at 1844 Market Street and 323 Octavia Street, where a $295 new-client special covers two sessions, a dietitian consult and a DEXA scan.
Custom Fit charges no membership or initiation fee to its training clients; you pay for sessions, and the DEXA scans, VO2 max tests and sauna-and-cold-plunge room come bundled in. The studio's entry point is a $295 new-client special: two 60-minute personal training sessions, a consult with a registered dietitian and a DEXA body scan. Its two San Francisco addresses sit close together near where Market Street meets Octavia Boulevard, at 1844 Market Street and 323 Octavia Street, so a search for personal trainer near me from Hayes Valley lands right on the door.

Evan Mather's Data-First Gym
Owner Evan Mather grew up in Oregon and came to coaching through water polo, powerlifting and yoga, and he is also one of the studio's DEXA technicians. In his own words, he opened Custom Fit to offer the best personal training and nutrition services he could, with every trainer following a shared protocol built on core strength, functional movement, correct form and nutrition, then adjusted to each client and tracked over time.
The testing lab is what turns that protocol into numbers. Mark Eaton, the director of sports performance and testing, is an ACSM-certified exercise physiologist with a kinesiology degree from San Francisco State and a bone densitometry certification from UC San Diego. Scans are run by a registered dietitian or an exercise physiologist, and the team sets aside 30 minutes to walk you through the results instead of emailing a PDF.
Three Studios and Eight Rogue Racks
The space covers 8,000 square feet across three studios, with eight Rogue squat racks, specialty bars, resistance machines, Woodway treadmills, Concept2 equipment and Rogue assault bikes. Large south-facing windows bring in afternoon light, and the event studio has been used for shoots by brands including Lululemon and the New York Times. Clients describe it as clean, well organized and unpretentious, and above all never crowded.
The locker rooms are a quiet selling point. Towels, private bathrooms and showers, Aesop products, deodorant, hair ties and feminine care supplies are all provided, so a pre-work session does not require hauling a full kit across town. Sleds, battle ropes and kettlebells give trainers plenty of ways to vary a session. A third location at 570 Battery Street is listed as coming soon for Financial District clients.
What Training Here Costs
Beyond the $295 intro, the studio quotes training packages after your first sessions, but its posted perks are clear: every training package includes unlimited DEXA scans, VO2 max testing, unlimited recovery room bookings, unlimited group classes and a 20-minute nutrition strategy session. One reviewer who bought a 20-session pack called it definitely worth it. Partner training is also offered, and couples who train together are a recurring theme in the reviews.
If you would rather lift on your own, two memberships are posted. Tier 1 is $240 a month plus a $100 initiation fee, with unlimited gym access, group classes and five recovery sessions a month. Tier 2 is $340 a month with no initiation fee and adds unlimited recovery, DEXA and VO2 testing. Our take: if you plan to scan monthly and use the plunge often, Tier 2 beats paying for tests separately.
The Recovery Room Rules
Recovery happens in a private room with an infrared sauna that reaches 175 degrees Fahrenheit and a cold plunge held at 43 degrees. Sessions are booked on the hour, up to two weeks ahead, and you can bring a guest for free. Reservations run 8 am to 7 pm on weekdays and 9 am to 4 pm on weekends, with same-day slots sometimes open by phone.
Non-members can buy access separately: two reservations cost $99 for new clients, four cost $260 and eight cost $440. Sports massage comes through MELtivity and SF Integrative Massage, and one-on-one physical therapy is available through partner Agile Physical Therapy, staffed by doctors of physical therapy rather than aides. If you are rehabbing an injury, ask your trainer to coordinate with the PT so the two plans line up.
Who Signs Up
The reviews sketch the regulars well. There is the couple training together with Evan despite different goals, the client who had not set foot in a gym in more than 20 years and felt hooked after two sessions with trainer Anthony Dandrea, and a mother of three who says her program is worth the sweat and the cash. Trainers named by clients include Brandon and Lu Green, and the blog speaks directly to desk workers and people starting fitness after 50.
Hours, Holidays and the Walk Over
The gym is open 6 am to 8 pm on weekdays and 7 am to 7 pm on weekends. It closes on July 4, November 26 and 27, December 24 and 25, and January 1, so plan Thanksgiving week accordingly. Van Ness Muni Metro station is a short walk east along Market Street, and the F Market streetcar and several bus lines stop nearby. Street parking is metered, and the studio notes a four-car loading zone out front.
After a session, walk north up Octavia Boulevard to Patricia's Green, the small park in the middle of Hayes Valley, and continue into the shops along Hayes Street. If an evening slot is full, book a weekend morning instead; weekend hours run until 7 pm, which is longer than many boutique studios in the city.
Practical Notes
Addresses: Custom Fit, 1844 Market Street and 323 Octavia Street, San Francisco, CA 94102. Hours: Monday to Friday 6 am to 8 pm, Saturday and Sunday 7 am to 7 pm. New-client special: $295 for two sessions, a dietitian consult and a DEXA scan. Gym memberships: $240 a month plus $100 initiation, or $340 a month with no initiation.
Bring training shoes and a water bottle; towels and toiletries are supplied. Book the DEXA scan for your first week so your trainer has baseline numbers, then rescan after a training block to see what changed. To compare Custom Fit with other data-driven studios nearby, ask Karpo in the Karpo APP for personal trainers within a short walk of Market and Octavia.
