Agent-first by design

Bring your own coach.

Most fitness apps bolt on a chatbot and charge you for it. MyoAmigo does the opposite: it opens your training data to the assistant you already use (Claude, ChatGPT, Gemini) through MCP, the open protocol AI agents use to work with real apps.

How it works

Built on your real numbers.

Connect once, with your account's permission, and your assistant can see what you actually lift, then act on it.

  • Reads your history: sets, PRs, estimated 1RMs, muscle-volume balance, consistency, week-by-week trends.
  • Writes real programming. Routines and weekly plans it drafts appear in the app, scheduled and ready to run.
  • Logs for you: dictate a set or a run to your assistant, and it lands in your training log.
  • Judges sessions like the app does, with the same honest verdict engine available to your agent.
  • Estimates starting weights for lifts you've never logged, inferred from the ones you have.

You, via your assistant

How did this training block actually go?

Coach

Ten weeks, 48 sessions, one missed day. Squat top set moved 245 → 290 lb; deadlift e1RM is 413 lb, a PR. Your shoulder press has been flat for six sessions, so that's the one to change.

You

Fix it in next week's plan.

Coach

I've updated Push Day: shoulder press drops to 105 lb for a 3×8 rebuild, with lateral raises moved up. It's on your Monday.

What your agent can reach

The tool surface.

Every tool is scoped to your account and gated by sign-in. This is the actual production surface, live today. Reading and analysis are free — connect your assistant and it can read your training and draft a plan at no cost; letting it write back (log sets, build routines and weekly plans) is MyoAmigo Pro.

Read

Training history

Workouts with full set detail, per-exercise history, PRs, cardio, body metrics, and a dense context snapshot built for agents.

Analyze

The same engines as the app

Strength standards, muscle-volume vs. evidence bands, consistency streaks, stall detection, session verdicts, week in review.

Write

Programming that lands

Create and revise routines and weekly plans; log sets and cardio with idempotency keys so a retry never double-logs.

On your terms

Gated, audited, yours.

Interactive clients ride the same OAuth sign-in as the app; headless ones use a single personal API key you can rotate or revoke. Nothing is shared by default. Disconnect anytime. Your data is never used to train models, never sold, never shown to another user's agent.
