Here’s how SKfit Personal Training works:
First, we start with a free consultation where we discuss your goals and work together to create a plan.
Next, once you’ve purchased the training package, we schedule an assessment meeting right away (it’s part of your package).
Then, during this assessment, we gather information and tailor a plan specifically for you based on your goals.
Finally, we kick off with our first session, starting your fitness journey!

Personal Training in San Diego, CA 92103
Since 2011, SKfit has been built on one standard: elite, uncompromised coaching. After two decades and four markets, San Diego isn’t just another location on the map — it’s the flagship home of everything SKfit has become.

Two Decades of Coaching Behind Every Session
SKfit San Diego is led by Sly, a NASM-certified personal trainer holding CPT, PES, CES, FNS and SFS credentials, with more than 20 years of coaching behind him. He has led award-winning training facilities in San Diego, Chicago, North Carolina and New Jersey, and his studios have 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 — no rotating staff, no cookie-cutter templates.
A Private Studio, Not a Crowded Gym Floor
Our private personal training studio sits at 3919 4th Ave, Suite F, in the heart of San Diego’s 92103 area, serving clients from Hillcrest, Mission Hills, Bankers Hill, University Heights, North Park and downtown. It was purpose-built for one-on-one work: no waiting on equipment, no membership fees, no start-up costs and no audience. Just a focused space designed around the person actually doing the work.
Most Programs Give You a Routine. We Build an Ecosystem.
Whether you are rebuilding a baseline after years away, training for longevity, or chasing a number you have never hit, the process is the same — assess honestly, program precisely, hold the line on accountability. That means 20+ years of coaching expertise rooted in strength, conditioning and longevity programming; a professional studio built specifically for one-on-one development; and recovery protocols and accountability tailored to your career, your schedule and your goals.
Ready to Raise Your Standard?
We don’t do mass-market fitness. SKfit San Diego works with people who are serious about their results, their health and their performance. Book your free consultation and let’s get to work.
