For coaches and trainers

# Your method, as an agent. Your roster, run by chat.

Agents4 Fitness turns how you coach into an AI agent that coaches your clients by your rules. Build it in Claude, in ChatGPT or in the app. Then ask it about any client and change one plan, or a whole group's, in a sentence: remove equipment that's gone, add a meal, swap an exercise. Free for 14 days with up to 5 clients. No card needed.

## What you can do by chat

- **Ask about any client:** “How's Sarah doing this week?” Your agent answers from her logged sessions, check-ins, nutrition and watch data, and tells you who on your roster needs you first.
- **Change a plan in a sentence:** A client trains at home now: remove the cable machine and every exercise that needs it is swapped for one that doesn't. Add a meal, swap a food, move a training day or shift calories and macros, and the day re-portions to match.
- **Change a whole group at once:** Put clients in a group (a gym, a team, a challenge) and one message changes every plan in it: remove equipment that's out of order, swap an exercise or add a meal. You see the preview first, and each client keeps their own sets and reps.
- **Nothing changes until you say yes:** Ask for a plan change or a message to clients and you see it first; it goes when you say yes. Day to day, each client runs the way you choose: Full Auto, Review First or Approve Each.

From Claude or ChatGPT (Architect plan) a group change goes further: add or remove exercises, rewrite a session, or shift calories, macros and foods for everyone in the group.

### Examples

- **Ask about a client** (Coach Assistant · in the app): “How's Sarah doing this week? Anything I should jump on?” Sarah logged 4 of her 5 sessions and hit her protein target 5 days out of 7. Thursday's check-in mentions her left knee on lunges, and her sleep has averaged about six hours.
- **Remove equipment** (Coach Assistant · in the app): “Jamal is training at home for a while, no cable machine. Swap out everything in his plan that needs it.” That changes four exercises in two of Jamal's sessions. Each one is swapped for the closest move that doesn't need cables, with his sets and reps kept: triceps pushdown becomes overhead triceps extension, cable lateral raise becomes dumbbell lateral raise. Apply it?
- **Add a meal** (Coach Assistant · in the app): “Add an evening snack after dinner to Maya's training days: 200 g of Greek yogurt and 80 g of blueberries.” That adds an evening snack after dinner on Maya's training days: 200 g Greek yogurt and 80 g blueberries. Her daily targets stay the same, so her other meals are re-portioned around it. Apply it?
- **Change a whole group** (Coach Assistant · in the app): “The leg press at Powell St is out of order. Take it out of the plans for that group.” Preview: the leg press comes out of 14 plans in your Powell St group, from now on. Each client gets the closest lift that doesn't need it, a barbell back squat here, and keeps their own sets and reps. Apply it?
- **Build an agent** (Claude · connected to Agents4 Fitness): “Here's my 12-week hypertrophy program. Build my coaching agent from it, exactly as written.” I've read the program and built your agent from it: the split, the progressions and the nutrition days, as written. It's saved in your workspace as a draft, so nothing reaches a client until you put it live.

## Your plan is intricate. Your agent keeps every layer.

A real coaching plan is not a list of exercises. It is programs for different clients, a week with reasons behind it, nutrition that changes with the day, and rules you would never let an assistant break. All of that goes in, and you can tune each layer afterwards.

An example page of a coach's program (Built To Last, 12-week recomp · coach's program, page 3), and what the agent keeps of it:

- **Several programs in one agent:** A program for each kind of client you coach; Every client matched to theirs at intake; Who each one is for: goal and experience. Add a program, rename one, or change which is the default. From the program: “New lifters: 3-day full body. Intermediates: 4-day upper / lower. Coming back from a layoff: start in the Rebuild block.”
- **The week, as you wrote it:** Sessions pinned to weekdays, rest days included; Sets, reps, rest and your notes on every exercise; Your blocks, warm-ups and progression notes. Change a session by chat, for one client or a whole group. From the program: “Mon · Lower A — Back squat 4 × 6-8, rest 150 s, 3 s down, leave 2 in the tank. RDL 3 × 8-10. Walking lunge 3 × 12 a side.” “Wed · rest + 30 min walk. Sat · conditioning, optional.”
- **Nutrition that changes with the day:** Training, rest and refeed days, linked to the session; Each food fixed as you wrote it, or scaled to the client; Every client's own calories and macros, from your rules. Shift a day's targets, swap a food or add a meal. From the program: “Training day 2,100 kcal. Rest day: same protein, carbs down a fifth. Refeed on Saturday.” “Dinner: salmon 170 g (do not scale), potatoes scale with carbs.”
- **The rules you coach by:** How you deload, program cardio and manage fatigue; Your signature exercises, and the ones you never use; Your cues and your demo video on any exercise. Rewrite a rule and every plan built after it follows. From the program: “Deload every 4th week: volume down 40%, keep the load. Two zone 2 sessions, never the day before legs.” “Knee pain: no lunges, step-ups instead. Squat cue: “own the bottom position”.”
- **What happens on a bad day:** Your thresholds for HRV, sleep, resting heart rate and strain; What changes on a yellow, orange or red day; Act on its own, propose it to you first, or only alert you. Set the thresholds and how much it may change without you. From the program: “HRV down two mornings, or under 6 h sleep: drop a set, keep the session. Red day: walk and mobility only.”
- **How it talks, and what it won't touch:** Your tone, your coaching style, your behaviour rules; Topics it never discusses, such as medication; When it stops and hands the conversation to you. Switch a boundary on or off, or add a rule in your own words. From the program: “Direct, no fluff, celebrate PRs. Supplements and medication: send them to me.”

### What you can hand over

**PDF, Word, Excel or CSV, Screenshots of a plan.** Programs and meal plans are read from your files and screenshots, and you review what was read before it becomes your agent.

**Videos, YouTube links, Voice notes, Documents.** Videos, YouTube links, voice notes and documents become the knowledge your agent answers from, in your words.

## Three ways to build your agent

- **In Claude — Hand it your program:** Connect Agents4 Fitness to Claude, give it your program and say “build my coaching agent from this, exactly as written.” The agent is created in your workspace as a draft, not left in a chat transcript. (Architect plan.)
- **In ChatGPT — Use the AI you already use:** The same connector works in ChatGPT: sign in with your Agents4 Fitness username and password, approve, and upload the PDF. Code editors such as Claude Code and Cursor connect with an API key. (Architect plan.)
- **In the app — Agent Studio, on every plan:** Start from a template or a blank page, or import the program you already have: a PDF, Word or Excel file, or screenshots of a plan. Review what was read, add your videos and voice notes, test it as a client, then put it live. (Every plan, and the free pilot.)

On the Architect plan, hand the same files to Claude or ChatGPT and say “build my agent from this, exactly as written”. It copies the program as written, asks you about anything unclear, and saves a draft.

### Before a client ever talks to it

- **A draft until you say so:** Nothing reaches a client while you are still building. You decide when it goes live.
- **Tested as a client first:** Talk to it as a test client, and preview the training and nutrition plans it would write for them.
- **A safety check it has to pass:** 14 test conversations run before it goes live. If it handles the injury or the supplement question badly, it does not go live.
- **Every version kept:** Each time you put a new version live, the last one is saved. Go back to it in one step.

## What your agent earns you

- **Coach more people, the way you coach** (Today): Your agent coaches every client you invite, by your rules, at any hour. Your plan covers their AI coaching: 15, 75 or unlimited clients.
- **Sell your method beyond your roster** (Coming soon): Selling your agent to members on the marketplace is coming soon, with 80% of each subscription going to the coach. Your method stays private: members are coached by it, they never see the files.

Your programs stay in your workspace. Clients are coached by your agent; they never see or download the files you built it from. [How to connect ChatGPT or Claude](https://agents4fitness.com/help/connect-ai).

## You decide how much it does alone

Not replacing coaches. Multiplying them. For check-in replies, each client runs in the mode you choose:

- **Full Auto:** Your agent replies to a client's check-ins on its own, by the rules you set.
- **Review First:** The AI drafts the reply and you get a window to edit or stop it before it sends.
- **Approve Each:** You review and edit each reply before it goes.

## Questions coaches ask

### How do I build my agent?

Three ways. In the app, Agent Studio walks you through it: start from a template or from scratch, or import the program you already have from a PDF, Word or Excel file, or screenshots of a plan, and review what was read before it becomes your agent. Your agent keeps the layers of a real program: a program for each kind of client, the training week as written, nutrition days whose foods are fixed or scale to each client, your deload and cardio rules, what happens on a low-readiness day, your voice and the topics it will not touch. You can add YouTube links, videos and voice notes for it to answer from, test it as a client, then put it live. That is included on every plan and in the free pilot. On the Architect plan you can also connect ChatGPT or Claude, hand over your program and ask it to build the agent exactly as written; it is created in your workspace as a draft.

### Can I really change a client's plan by chat?

Yes. Tell the Coach Assistant what should change: remove equipment when a machine is out of order or a client trains at home (every exercise that needs it is swapped for one that doesn't), add a meal, swap an exercise or a food, add or remove an exercise, change sets or rest, move a training day, or shift calories and macros. It shows you the change, applies it when you say yes, and the client sees it in their app. For a group, one message removes equipment, swaps an exercise or adds a meal in every plan in the group, and keeps each client's own sets and reps.

### What can I ask it about my clients?

Anything you would ask an assistant coach who had read every log: how a client's week went, who missed sessions, what a check-in said, who needs attention first. It answers from that client's logged workouts, check-ins, nutrition and watch data.

### Does the AI talk to my clients without me?

Only as far as you allow. Each client runs in the mode you choose. Full Auto: your agent replies to check-ins on its own, by your rules. Review First: the AI drafts and you get a window to edit before it sends. Approve Each: you review and edit each reply before it goes. You can change the mode for any client at any time.

### Which AI apps can I connect?

ChatGPT and Claude, on the Architect plan. You add Agents4 Fitness as a connector in the AI app, sign in with your Agents4 Fitness username and password, and approve the connection. Code editors such as Claude Code, Cursor and VS Code connect with an API key. The step-by-step guide is at agents4fitness.com/help/connect-ai.

### What happens to my programs and methods?

They stay yours, in your workspace. Clients are coached by your agent through the product; they never see or download the files you built it from.

### What does it cost?

Every new coach gets a free 14-day pilot with up to 5 clients and AI coaching switched on, no card needed. After that: Solo is $29/mo for up to 15 clients, Studio is $79/mo for up to 75, and Architect is $199/mo for unlimited clients plus connecting ChatGPT and Claude and the Analyst. Annual billing is available on each plan.
