02 — About the coach

Meet Anthony

Fitness isn't about chasing perfection, it's about becoming stronger, healthier, and more confident in what your body can do. My mission is to help you build habits that create lasting results, both inside and outside the gym.

Every client receives a personalized plan built around their goals, lifestyle, experience, and individual needs. No two people are the same, so your coaching shouldn't be either.

Whether you're stepping into the gym for the first time or working toward your next level, I'm here to provide the guidance, accountability, and education you need to build confidence and achieve results that last.

Client Testimonials

Unedited words from people who stuck with the process.

I'd bounced between programs for years. Anthony was the first coach who explained why, and once I understood the plan, staying consistent stopped being a fight.

The nutrition side was what I dreaded most, and it ended up being the easiest part. No banned foods, no guilt. Just targets I could actually hit on a work week.

I walked in nervous about my back and walked out with a plan that worked around it. Six months later I'm lifting heavier than before the injury, with no pain.

What I didn't expect was how much confidence carried outside the gym. I trust myself to follow through on things now, and that started with showing up here.

05 — WHY THIS COACHING IS DIFFERENT

Train With Purpose

Train with intention. Build strength, confidence, and habits that last a lifetime.

My coaching is built around intentional training, personalized programming, practical nutrition, and consistent accountability. Every workout has a purpose, every habit has meaning, and every step is designed to help you build lasting strength, confidence, and a healthier lifestyle, not just short-term results.

The goal isn't temporary motivation.
It's lifelong confidence.

Education
You learn the why behind every block.
Progression
Programs evolve as you do, never static.
Support
Weekly check-ins and real accountability.

Step four

Build Results That Last

Progression reviews keep the plan evolving — so results compound instead of resetting.

07 — FAQ

Questions, answered.

No. Most clients start with little or no lifting background. We begin with movement basics and build from there — you'll never be handed a program you don't understand.

Yes. Online programs are written for whatever you have access to — a full gym, a garage setup, or bodyweight and a pair of bands.

We audit your equipment on the consultation call and build the program around it. Nothing gets recommended that you'd have to buy to start.

Training blocks typically run 4–6 weeks, with weekly adjustments based on your check-ins. Progression is continuous, not a rewrite every month.

All 1-1 in person training sessions are held at Extreme Fitness. Once your first session is complete, you'll receive everything you need to know before your first session, including where to meet and what to bring.[2390 Boswell Rd, Chula Vista, CA 91914]

Always. Online, nutrition, and in-person all start with a free session 

Strength and energy usually shift within 3–4 weeks; visible body composition changes typically show around 8–12 weeks of consistent training and nutrition. We track progress weekly so you can see movement long before the mirror shows it.

We screen for it on the consultation call and program around limitations with modified movements and controlled loading. For anything under active medical care, I work alongside your provider's guidance — never against it.

No membership is required for your first session. If you choose to continue training, an active Extreme Fitness membership is required, as all in-person coaching is provided through Extreme Fitness's Personal Training Program with Anthony as your coach.
