Corset guiding a bird-dog exercise: the movement figure, set 1 of 2, rep 3 of 5, and a hold timer.
Follow the movement. Corset keeps the time.

How it works

From your AI chat to a session you can follow

  1. Bring your routine

    Ask your AI assistant to put your exercises in Corset. Start with your physio's sheet, an exercise list or a routine from your chat.

  2. Review and add it

    Open the link from Claude, or paste the answer from another AI. Check the exercises, reps and timings before you add the routine.

  3. Follow the session

    Corset counts the reps and times the holds and rests. Check in afterwards to keep a record of your sessions and how you feel.

Your own exercises

Bring the routine you already have

Use Claude to turn your exercises into a routine link that opens in Corset. If you use ChatGPT, Gemini or another assistant, Corset gives you a message to copy into the chat.

  • Start with a physio's sheet, an exercise list or a routine from your chat.
  • Review the exercises, reps and timings before you add it.
  • Exercises Corset recognises get a figure and voice cues. Others use written instructions and a timer.

At your pace

There’s room for rest days

You can take time off or ease back without falling behind your weekly target.

Taking a day off

Choose “Take today off” in the app. Corset adjusts your target for the week.

During a flare-up

Choose “It's flaring up” to take it easy for a while. Routines with a lighter stage step back where one is available.

Saved on your device

Your routines and check-ins are saved on this device. Export a summary to discuss with your physio, and save a backup before changing phones or clearing browser data.

Free while we’re getting started

All routines and features are currently free. No account or payment details needed. Any future pricing will be explained here.

Before you start

Corset is exercise guidance, not medical advice. It doesn't check whether a routine suits you. Stop if something hurts sharply.

Common questions

Do I need to use AI?

No. You can choose a library routine and start in Corset. An AI assistant is an optional way to turn your own exercise sheet into a routine the app can read.

What does the progress record tell me?

It shows the sessions you completed and your answers about how you feel over time. That gives you something concrete to look back on or discuss with your physio. It doesn't establish why things changed or whether an exercise is right for you.

Can I use Corset on my phone?

Yes. Open Corset in Safari, Chrome or Edge, and add it to your home screen if you'd like. After the first load, sessions at the default voice pace and your log work offline. The Android app is coming to Google Play; an iPhone app follows later.
