FAQ
You got questions. We got answers.
Will I lose strength?
No — our nutrition systems are built to fuel performance, not starve it. Every plan is designed around preserving (and often increasing) lean muscle and training output while improving body composition, recovery, and energy.
How fast will I see results?
Most clients notice measurable progress in the first2–4 weeks, depending on consistency and starting point. Within30 days, you’ll have visible changes in body composition, energy, and daily performance — that’s the standard we aim for.
What if I travel a lot?
We build your plan around yourreal life.Whether you’re traveling for work, competing, or vacationing, your coach adjusts your strategy so you stay on track. No falling off — just flexible solutions that keep progress moving. Not to mention we have multiple tracks built around home/ garage/hotel gyms... or even no gym at all!
Can I swap between training or nutrition tracks?
Absolutely. As your goals evolve, your plan can too. You can switch between training tracks (Muscle Anarchy, Machine Head, Beach Babe, Booty Babe, Bodyweight Babe, etc.) or adjust nutrition tiers (Foundations → Comprehensive → Premier) with coach approval.
How does the doctor visit work (Premier Tier)?
Premier clients receive a coordinated, white-glove experience. Your onboarding includes a telehealth consultation with our partnered physician network for labs, hormone optimization, and medical oversight. Everything is scheduled and handled for you — no extra steps. A medical professional will reach out to you personally for all scheduling and information gathering.
What if I’m completely new to nutrition?
That’s exactly whatComprehensive Coachingis for. You’ll learn everything — from how to eat for your goals to how to make sustainable choices. Our goal is to make you confident and capable, not dependent.
Can I upgrade or downgrade my plan later?
Yes — flexibility is built in. You can move up to a higher tier for more support or drop down when you’re ready to take more ownership. Your coach will help you transition seamlessly.
Do I have to track macros or calories?
Only if it fits your level. Some clients thrive on detailed tracking; others a fully written out diet plan. Match your plan to your lifestyle — precision for those who want it, simplicity for those who need it.
What happens after the first 3 months?
You can continue month-to-month or renew quarterly for discounted rates. Most clients choose to stay long-term because results compound — and continued coaching ensures progress doesn’t plateau.
Is this a diet plan or a lifestyle system?
This isn’t a “diet.” It’s acustom frameworkbuilt around performance, longevity, and sustainability. We teach you how to eat for life — not for a 30-day challenge.
