Published ChatGPT plugin
Connect ChatGPT to your real workout history.
Simple Muscle gives ChatGPT permissioned access to your planned workouts and the sessions you actually completed. It can build and adjust the plan while completed history remains read-only.

Real workout data
Useful access, with a hard boundary.
ChatGPT can help plan and analyze training without rewriting what actually happened in the gym.
Change
The workouts you plan to perform
Create a complete multi-day plan, then open a workout to edit exercises, sets, reps, weight, duration, notes, order, and schedule labels. In the workout plan editor, review draft changes before choosing Save changes.
Protected
Completed workout history
What you actually completed stays read-only. ChatGPT can analyze those sessions, but it cannot edit or delete them.
First conversation
Try these after connecting.
“Create a three-day strength plan for Monday, Wednesday, and Friday. Use exercises available in Simple Muscle and save the complete plan.”
“Review my completed workouts from the last four weeks. Show my training frequency and where my volume has changed most.”
“Open my workout plan. Use my recent bench press history to propose a conservative target for next week, and let me review the draft before saving.”
Your account stays yours.
The connection opens Simple Muscle’s normal sign-in and grants tools only after you authorize it. ChatGPT never needs your Simple Muscle password.
- Authorization uses OAuth and your normal Simple Muscle sign-in—not an API key pasted into ChatGPT.
- Read and write capabilities are declared to the host so ChatGPT can distinguish inspection from changes.
- You can disconnect Simple Muscle from ChatGPT and revoke the authorization when you no longer want it connected.
- Completed sessions are a read-only record even though planned workouts can be edited.
Questions
Before you connect
Is this the same as pasting a workout prompt into ChatGPT?
No. A prompt gives ChatGPT the details you type into that conversation. The Simple Muscle connection gives it permissioned tools for your saved workout plans and history, so it can work with current structured data instead of relying on copied text or screenshots.
What if I can’t install the plugin?
Plugin availability can depend on your ChatGPT plan, region, workspace, and administrator settings. Open the listing while signed in to ChatGPT and check your workspace's plugin access if the install control is missing.
Can ChatGPT change workouts without asking?
ChatGPT can call the workout-editing tools you authorize, and the host controls how write and destructive confirmations appear. Review proposed changes and tool confirmations, especially when removing an exercise or deleting a workout template.
Can ChatGPT change a workout I already completed?
No. Completed workout history is read-only. ChatGPT can read and analyze those sessions, while edits apply to workout templates you plan to perform in the future.
Do I need a separate OpenAI API account or API key?
No. This is a connection inside ChatGPT. You use your existing ChatGPT account and sign in to your Simple Muscle account during authorization.
Provider setup details verified against OpenAI’s plugin documentation.
