Fair use, in plain words
Your pass includes fair use monthly limits on AI conversations and generated images, so every member gets fast service. Your partner tells you in the chat the moment you reach a limit, and limits reset on your billing date. No overage bills, no surprises. Fit AI gives training and nutrition guidance for generally healthy adults. It is not medical advice and it does not diagnose anything. Sharp, new or worsening pain, chest pain, numbness or dizziness means stop and see a doctor or physical therapist.
🧰 Tools
Real tools that run right here in the app. No AI actions used, and they keep working when your AI bar is empty.
AI Coach ● Fit AI
Your accountability partner is ready. Ask for a workout, a meal plan, an exercise swap, or a straight consistency check.
🛒 Fitness Store
Curated for your goals, from Tony's own shelves at 2 Brothers and Amazon.
Make Fit AI yours
Your partner ships named Fit AI. Rename it, set its personality and voice, and give it your profile. It builds every workout and meal plan from this.
Your profile
This is the private layer your partner builds from: your body weight, your goal, your equipment and your food notes. It saves with your cloud account when you sign in, so your coach builds from it on any device.
What Fit AI has learned
Your private memory layer. Add facts about your training, your limits and your schedule, and your partner will work from them.
Coming next: consistency on autopilot
Connections are the next milestone and are not live yet. When they open, you will connect your platforms once, on their own official pages, and from then on your partner keeps your training days, meal prep blocks and check ins in front of you, and helps you share your progress inside your monthly limits.
Your passwords are never asked for and never stored. Every connection is an official sign in that you can revoke anytime.
How autopilot will work
When connections open:
1. Tap Connect on a platform and sign in on that platform's own page.
2. Tell your partner your training days and prep day, or approve the weekly rhythm it drafts for you.
3. It keeps reminders, check ins and progress posts moving inside your monthly limits and reports back in your chat.
4. Calendar connections keep your workouts and prep blocks straight, with a nudge before each one.
Your streak
Log your first workout below and your partner starts counting.
Log a workout
Weight log
Weigh in when it helps you, not as a daily verdict. Your partner watches the trend with you.
My Plans
Your plan files live here. Ask your partner in Chat for a workout plan, a meal plan or a recovery plan, then tap Save as plan under its answer. Set a start date and the plan lands on your calendar.
Gold ring is today. Dots mark plan days: green training, amber meals, red recovery. A small diamond marks your own entries; tap a day to add one. While a recovery plan is active, training days show as recovery days until you are cleared.
The 2 Brothers Store
The gear, fuel and merch your plans call for, from Tony's own shelves. Links open Tony's Amazon storefront, his tagged Amazon picks, or fuelyourflow.net. Purchases run through Amazon and Fuel Your Flow, and Tony earns his usual commission at no extra cost to you.
Supplements
General fitness staples members ask about most. These are food and supplement products, not medicine: follow the label, and check with your own clinician if you take medication or have a condition.
Merch
2 Brothers gear and the books, from Fuel Your Flow.
Equipment
The home gym basics our plans are built around.
RecoverWell
Tell your partner what hurts or what happened. It builds a phased recovery plan in Chat; save it to My Plans with one tap, set its start date, and your calendar training days swap to recovery days until you are cleared. Recovery is part of the program, not a day off from it.
Start a recovery plan
First, a straight safety check. Tick anything that is true right now:
Your partner asks in Chat, builds the phased plan there, and you save it with the Save as plan button under the answer. No diagnosis, ever: this is guided recovery for everyday training aches.
🥗 Macro & Calorie Calculator
Your daily numbers, figured on the spot from the Mifflin-St Jeor equation, plus the 2 Brothers hand portion system from the book, so you can build a plate without a scale.
Estimates from the Mifflin-St Jeor equation, the standard starting point. Adjust by the trend: if your weight is not moving the way your goal needs after two honest weeks, shift the target by 100 to 200 calories.
🏋️ 1RM Calculator
Enter a set you actually did and get your estimated one rep max with the Epley formula, plus the working weights your next sessions are built from.
An estimate, not a test. Never attempt a true one rep max alone or without proper warm up sets and a spotter. The estimate gets less reliable above 10 reps.
⏱️ Rest Timer
Rest is part of the program. Pick your rest, start the clock, and get back under the bar when it beeps.
Short rests (30 to 60s) suit isolation work and conditioning. Longer rests (2 to 3 min) suit heavy compound lifts, so the next set gets your full strength.
More
Everything else in Fit AI, one tap away.
📚 The 2 Brothers Library
The full 2 Brothers book and the three plan PDFs, included with your Fit AI pass. Download them, print them, work them. The library spends no AI actions and keeps working when your AI bar is empty.
How the plans fit together
Start with the 7-Day Kickstart to learn the rhythm. Run the 30-Day Foundation to build the base. Then take on the 90, the plan form of the book itself. Your AI coach personalizes any of them to your body, your goal and your equipment: ask in Chat and save the answer as your own plan.
🤝 Accountability Corner
Will you be my accountability partner and start a fitness journey with me?
Invite a friend by email. When they join Fit AI with that email, you are connected automatically. You choose what each partner can see of yours: your workout calendar, your meal plan check-ins, both, or nothing. Weight and health measurements are never shared. Free for every member, and it spends no AI actions.

Accountability Corner is being switched on.
