What kind of personal training do you offer in Irvine, CA?

Crown Fitness offers private 1-on-1 personal training and semi-private personal training (2-3 clients per session) at our studios in Irvine, CA. Every session is coach-led, science-based, and built around your specific goals — whether that's fat loss, muscle building, body recomposition, or long-term performance.

Do you offer personal training near Newport Beach and Costa Mesa?

Yes. Our primary studio is in Irvine at Sky Park Circle, and we train clients from Newport Beach, Costa Mesa, Tustin, and throughout Orange County. Our location on the Irvine/Costa Mesa border makes us a convenient option for anyone in South OC looking for private personal training.

What is the difference between private and semi-private personal training?

Private personal training is 1-on-1 — just you and your coach, fully focused on your program. Semi-private personal training has 2-3 clients per session, each with their own individualized program but sharing a coach. Both options deliver the same coaching quality; semi-private adds a social dynamic at a slightly lower investment.

Is Crown Fitness a gym membership?

No. Crown Fitness is a private personal training studio. You work with your coach by appointment only — no crowded gym floor, no drop-in classes, no big-box gym experience. Every session is personalized, scheduled, and run by a coach who knows your name, your goals, and your program.

Do you have personal trainers serving Tustin, CA?

Yes. Our Irvine studios are just minutes from Tustin and we have a strong client base throughout the Tustin area. Crown Fitness offers both private and semi-private personal training options that fit around your schedule.

What fat loss and body transformation results can I expect?

Our clients typically see meaningful fat loss, muscle gain, or body recomposition results within the first 1-3 months. Longer-term clients achieve significant weight loss and full-body transformation. Results depend on consistency and commitment to programming and nutrition — both of which your personal trainer actively supports.

How do I get started with a personal trainer at Crown Fitness?

Book a free fitness assessment through our website. We will get to know your goals, assess your current fitness level, and walk you through whether private or semi-private personal training is the right fit. No commitment required to get started.

Do you offer a community Run Club in Orange County?

Yes. Crown Fitness hosts a community Run Club in Irvine and Orange County, open to clients and community members looking to build endurance, accountability, and consistency alongside others. Your fitness coach may incorporate run club sessions into your overall personal training program.

Our Story

Built for people who don't have time to waste.

Crown Fitness started in 2020 when founder Prince Ofosu, a personal trainer with a degree in Human Biology from UCI, kept seeing the same problem across Orange County: big box gyms treated clients like a number, not a person. Too many people paid for memberships, showed up, and still didn't see results because no one held them accountable or built a plan around their actual goals.

"Every client starts with a real assessment, not a generic plan pulled off a shelf."

Prince set out to do personal training in Irvine, CA differently: structured programs, real coaching from personal trainers who know their clients by name, and a private setting instead of a crowded gym floor. Priscilla Castaneda and Josh Chen joined as co-owners and personal trainers early on, helping build the team and culture Crown Fitness is known for today.

Today, our personal trainers work with busy professionals at two studios in Irvine and a second location near Costa Mesa and Newport Beach, bringing the same structure, precision, and accountability to every client, no matter which studio they train at.
