An AI coach that knows your workout history

Good training advice starts with what you actually did. An assistant needs your recent sets, longer trends, and the plan you meant to follow before it can say whether to add weight, repeat a session, or change course. MyoAmigo is a lifting log for iPhone and Apple Watch with a connected training record that compatible AI assistants can read through the Model Context Protocol (MCP).

What changes when the coach can see the log?

A generic prompt such as “write me a leg day” can produce a plausible session. It cannot know that you squatted twice last week, missed Friday, or have been repeating the same load for six sessions. With permission to read a synced log, an assistant can ask MyoAmigo for the evidence before answering. You can then ask:

• “Review my last four weeks of bench press. Am I progressing or just changing reps?”
• “Which lifts have stalled? Show the sessions behind your answer.”
• “Which muscle groups have I trained most and least recently?”
• “Suggest a three-day week around the exercises I actually use.”

Those are questions, not guaranteed diagnoses. A useful assistant should cite the logged sessions it relied on, say when there is too little history, and let you decide what to do next.

From a workout log to an AI conversation

1. Record training in MyoAmigo. The core lifting log works on your device without an account. Your workouts and history remain available in Free.
2. Create an account and sync the history you want to discuss. A remote assistant cannot read workouts that exist only on your phone. Connecting the account makes its synced training record available to the authenticated MCP server.
3. Connect a compatible assistant. Add https://api.myoamigo.com/mcp in a client that supports remote MCP, sign in to MyoAmigo, and review the access you grant. See the connection guide for current client steps.
4. Ask a specific question. Name the lift and time period, then ask the assistant to show its evidence. If the history is incomplete, treat its recommendation as provisional.

MyoAmigo offers the training record and tools; the assistant account is separate. Provider features, plan requirements, and usage limits vary. You do not need an assistant subscription to keep logging workouts in MyoAmigo.

What can an assistant read or change?

MyoAmigo’s account-scoped MCP tools can read synced workouts, exercise history, personal records, stalls, and strength standards in Free. Deeper synthesized analysis, including a week review and full session assessment, requires Pro. With MyoAmigo Pro and a client that permits write actions, an assistant can create routines and weekly plans or log a set at your request. Review proposed changes before using them. The MCP reference and Free and Pro comparison show the current boundary.

Apple Health is a separate choice. Its data is not automatically available to a remote assistant: you must opt into the relevant Health category in MyoAmigo’s Data Sync Center and grant Apple’s permission. See our privacy policy. A connected provider handles data returned by the tools under its own terms.

Choose the assistant that fits your setup

Claude can connect through a remote MCP connector. Grok documents custom connectors on grok.com. ChatGPT can use custom MCP apps where OpenAI makes that feature available; its current plan and developer-mode limits matter, especially for write actions. Meta documents remote MCP in Muse Code, while a consumer Muse custom-connector path is not yet established in its published guide. These are independent connections, not formal MyoAmigo partnerships.

A better question to ask your AI coach

Try: “Look at my last eight bench sessions. Separate working sets from warm-ups. Tell me whether my top set, reps, or total work changed. If there is not enough evidence to call this a plateau, say so. Suggest one next-session target and explain why.” That request asks for a bounded observation and a useful decision, instead of a dramatic verdict from one workout.

Frequently asked questions

Can an AI coach see my previous workouts?

Yes, after you choose to sync your MyoAmigo account and connect a compatible MCP assistant. It sees the synced data returned when it calls a tool; workouts kept only on your phone are not visible to a remote assistant.

Do I need Pro to let an assistant read my training?

No. Workout history and core training analysis through MCP are Free. Pro includes deeper synthesized reviews and assistant write actions such as creating routines and weekly plans or logging sets. Your AI provider may have separate plan limits.

Does connecting an assistant share my Apple Health data?

Only Health categories you separately choose to sync can be available to a remote assistant. The category switch and Apple permission are both required.
