Connect ChatGPT to your workout history

If you ask ChatGPT about your lifting, the answer is only as useful as the history it can see. MyoAmigo stores your workouts in a log for iPhone and Apple Watch and offers a remote Model Context Protocol (MCP) server. Where your ChatGPT plan and workspace allow a custom MCP app, you can connect your synced MyoAmigo account so ChatGPT can request real training records during a conversation. This is a conditional setup, not a built-in ChatGPT feature available to every account.

First, know what ChatGPT currently allows

OpenAI says custom MCP apps are configured in developer mode. Full MCP support, including write actions, is in beta for ChatGPT Business, Enterprise, and Edu on the web; workspace administrators control who can add or publish an app. OpenAI says ChatGPT Pro users can use custom MCPs with read/fetch permissions in developer mode, but not full write support. Availability and action approvals may change. Check OpenAI’s current developer-mode guide before starting. MyoAmigo is not an OpenAI-approved app or an official OpenAI partnership.

How to connect a synced workout log

1. Log in MyoAmigo. Core workout recording works offline without an account. You can import a Strong CSV if you are moving an existing history.
2. Sign in to MyoAmigo and sync the workouts you want to discuss. The MCP server can return records from your account; it cannot read workouts that remain only on your iPhone.
3. In an eligible ChatGPT workspace, enable developer mode and create a custom app. Enter https://api.myoamigo.com/mcp as the remote MCP endpoint, choose the offered authentication flow, sign in to MyoAmigo, and let ChatGPT scan the tools. Your workspace may require an administrator to create or approve the app.
4. Use the app in a supported ChatGPT web conversation. Select it from the tools menu or mention it in your prompt. Ask ChatGPT to retrieve a specific lift or time period and show what it found.

Those are OpenAI’s general custom-app steps, not a claim that every ChatGPT account or tool combination has been tested with MyoAmigo. The MyoAmigo connection guide covers the server side. If tool scanning or sign-in fails, follow the error shown by ChatGPT and your workspace’s app policy.

What to ask once connected

Start with a question the log can answer: “Read my last six bench press sessions. Compare top working sets and total work. Which change is actually supported by the data?” You can also ask, “What did I train this week?” or “Which recent lifts show a stall?” Tell ChatGPT to cite the sessions it used and to say when the record is incomplete.

Your workouts do not become ChatGPT’s permanent memory. They remain in MyoAmigo and are returned when an authorized tool is called in a supported conversation. You may need to select the app again for a later message, as OpenAI describes.

Reading is different from writing

MyoAmigo’s Free MCP tools expose synced workout history, personal records, stalls, and strength standards. Its deeper synthesized week review and session assessment require MyoAmigo Pro. MyoAmigo Pro also enables training-data write tools, such as creating routines and plans or logging a set. ChatGPT can use a write tool only where OpenAI enables full MCP actions for your plan and workspace and the action is approved. A Pro purchase in MyoAmigo does not change ChatGPT’s provider limits; a ChatGPT subscription does not unlock MyoAmigo Pro. See MyoAmigo pricing and feature access.

Privacy and control

Connecting is optional. MyoAmigo scopes MCP tools to your signed-in account; ChatGPT receives only the data returned when it invokes a tool, then handles that data under OpenAI’s terms. Apple Health information requires a separate category opt-in and Apple permission before there is a server copy for an assistant to query. You can disconnect the app and control MyoAmigo sync. Read the MyoAmigo privacy policy and OpenAI’s app and permission guidance.

Frequently asked questions

Can ChatGPT see my workout history without me pasting it?

With an eligible custom MCP app, an authorized ChatGPT conversation can request synced history from your MyoAmigo account. It cannot reach workouts held only on your device.

Will ChatGPT remember my workouts forever?

No permanent ChatGPT memory is promised. MyoAmigo keeps the training record; ChatGPT requests data from it when you use the connected app and a tool is called.

Can ChatGPT log sets or write a plan into MyoAmigo?

MyoAmigo supports those MCP write tools with Pro. OpenAI currently limits full MCP write actions to eligible Business, Enterprise, and Edu workspaces in beta. The workspace and action permissions must allow them.

Does ChatGPT Pro alone unlock the connection?

OpenAI says Pro users can use custom MCPs with read/fetch permissions in developer mode, while full write actions require an eligible business or education workspace. Tool availability depends on the client’s current scan and permissions.

For other clients, see connect Claude to your workout log, connect Grok, or use Meta Muse Code. For the broader use case, read an AI coach that knows your workout history or browse the MCP tools.
