Common Questions
About an hour, all in one visit. We go through your goals, fitness history, and any injuries, then run a full strength and movement assessment so your plan starts from your real baseline. If another coach fits you better, we set up a complimentary hour with them too. Wear athletic clothes and be ready to move.
Private is 1-on-1 with your coach every session. Semi-private puts 2 to 3 clients in the same session, each with their own individualized program. Both get the same quality of coaching. Semi-private comes at a lower monthly cost and adds a layer of shared accountability.
We offer month-to-month and a 3-month commitment option. Most clients choose the 3-month because consistent structure produces faster results. All sessions are one hour, by appointment only. If you need to cancel, give us notice and we will schedule a makeup session.
Every program includes a custom meal plan, nutrition check-ins in person or through the app, and access to the Crown Fitness app. The app has your full workout plan, meal plan, progress log, and session tracking all in one place.
Yes. 766 St Clair St, Costa Mesa 92626 is where we train in Costa Mesa, by appointment, with two more studios in Irvine if you split your week between home and the office.
Yes. We have worked with and helped rehabilitate clients with a wide range of physical limitations. As long as you have clearance from your doctor, we will build a program that works safely and effectively around your body.
Primarily busy professionals who want real, lasting changes to their health and body and need coaching that fits into a demanding schedule. If you are looking for a drop-in gym or the lowest price in Orange County, we are probably not the right fit. If you want a real program, real coaching, and results that last, we would love to talk.
