Floor-to-ceiling windows. Steel structure. Your full Stark team in one space that doesn't feel like any gym you've been in.
Walk through the doors and the space does something to you. Vaulted ceilings, floor-to-ceiling windows, and an industrial aesthetic built around one purpose: performance. This isn't a gym you squeeze into. It's a facility that makes you want to do the work.
The Tustin / Irvine location brings the same integrated team model that defines Stark — doctor, coach, nutritionist, chiropractor, and neuromuscular therapist — into a space designed to match that ambition.

Every service at the Tustin / Irvine location works as part of an integrated plan — not isolated offerings.
Doctor, coach, nutritionist, chiropractor, and neuromuscular therapist — all working from your data, all accountable to each other.
Gold-standard body composition analysis. Track fat, muscle, and bone density with clinical precision. Standalone or as part of membership.
Comprehensive panels beyond standard labs. Hormones, inflammation, metabolic markers — reviewed by our functional medicine doctor.
Structural health that supports everything else. Our chiropractors work in concert with your coaches and doctor.
Recovery is part of the plan. On-site neuromuscular work integrated into your program — not an afterthought.
Personalized programming built around your biomarkers and recovery data. Not a template.
The space gets you in the door. The team is what keeps you coming back. At Tustin / Irvine, your doctor, coach, nutritionist, chiropractor, and neuromuscular therapist all work from the same data — and all communicate about your progress.
This is the ecosystem model. Not five separate conversations you have to coordinate yourself, but one integrated team with one unified plan. When something changes in your bloodwork, it changes your training. When recovery data shifts, nutrition adjusts. That's what makes Stark different.
Your functional medicine physician reviews your bloodwork, sets medical-grade baselines, and directs the protocol.
Your coach programs your training around your recovery data, lab results, and structural limitations. No generic templates.
Nutrition strategy built around your physiology and performance demands — updated when your data changes.
Structural and soft tissue work that supports your training load and recovery. Integrated into the plan, not a standalone add-on.
Start with your Stark Baseline — a comprehensive assessment that gives you real data, a real team, and a real plan built for you.
Tell us a bit about yourself and we'll be in touch within one business day to walk you through the next steps.
