Since 2011, SKfit has been built on one standard: elite, uncompromised coaching. After 24 years of coaching, San Diego isn't just another location on the map — it's the flagship home of everything SKfit has become.
Our private training studio is located at 3919 4th Ave, Suite F, right in the heart of San Diego's 92103 area — serving clients from Hillcrest, Mission Hills, Bankers Hill, University Heights, North Park, and downtown.
Work Directly With Sly — No Rotating Staff, No Cookie-Cutter Templates
SKfit San Diego is led by Sly, a
NASM-certified personal trainer holding CPT, PES, CES, FNS and SFS credentials, with 24 years of coaching behind him. SKfit has been named Best Personal Trainer by the San Diego A-List, Best Gym & Health Club by Uptown News, and Best Weight Loss Clinic by The San Diego Union-Tribune. When you train here, you work with him directly.
A Private Studio, Not a Crowded Gym Floor
Our studio was purpose-built for one-on-one work, which means:
- No waiting on equipment
- No membership fees or start-up costs
- No audience — just a focused space built around you
Whether you're rebuilding a baseline after years away, training for longevity, or chasing a number you've never hit, our approach stays the same: assess honestly, program precisely, hold the line on accountability.
