Fitness Operating System
Frequently Asked Questions
1. What is F.O.S.?
F.O.S. (Fitness Operating System) is the training and nutrition system I built over 20+ years of coaching. It’s an app with your training program, the Carb Logic™ nutrition tracker, an exercise video library, and progress tracking.
2. What’s the difference between Lite, Core, and Elite?
Lite is $97. It’s the system, self-guided: the training program, Carb Logic™ tracker, and exercise video library. Coaching isn’t included.
Core is $147, one time. It's everything in Lite, plus 30 days of coaching: weekly check-ins, custom macro adjustments, direct messaging with me (24 to 48 hour response), program modifications, and access to the private client community. Elite is $297 a month. It’s everything in Core, plus two 30-minute 1-on-1 video calls a month, same-day priority messaging, custom supplement and recovery protocols, program changes for travel, injury, or life, and quarterly progress reviews. Elite is limited to 15 clients.
3. How do I get started, and what happens after I pay?
Tap the button for your version. For Core and Elite it takes you to a secure Stripe payment page. For Lite, you'll enter your name and email first and get a payment link by email. After you pay, I email your F.O.S. login (a username and PIN) within a few hours. Open the app at mflowpt.net/fos-app, log in, and start Day 1.
4. Do I need to download an app?
No app-store download. F.O.S. runs in your phone’s browser. Add it to your home screen and it opens like an app.
5. Do I need a gym?
No. F.O.S. has a Home/No Gym version, with alternate movements for equipment you don’t have. If you’re coming back from an injury or need a senior or recovery version, email me at terrysfos@mflowpt.net and I’ll point you the right way.
6. How does the nutrition tracker work?
You log what you eat by category: protein, complex carbs, simple carbs, and vegetables. The tracker totals your macros and keeps your carb cutoff time in view.
7. What are the weekly check-ins?
Once a week you rate your energy, sleep, and hunger, note any soreness, and ask me questions. I use it to adjust your plan. Check-ins come with Core and Elite.
8. Can I switch plans later?
Yes. You can move up to Elite or scale back to Lite based on what you need. Email me at terrysfos@mflowpt.net.
9. How do I reach you?
terrysfos@mflowpt.net
10. Can I get a refund?
No. All sales are final, so pick the version that fits you. If you have a question before you buy, email me at terrysfos@mflowpt.net and I’ll answer it first.
11. Can I cancel?
Lite and Core are one-time payments, so there's nothing to cancel. Elite renews monthly until you cancel. To cancel Elite, email terrysfos@mflowpt.net. When Elite ends, coaching stops and you keep your F.O.S. login and training structure.
12. What happens after my 30 days of Core?
You keep your F.O.S. login and your training structure. If you want continued coaching, message me and we'll set up a monthly option.
