# Custom Exercises

> Create your own exercise when the built-in catalog doesn't cover something.

If the built-in catalog doesn't include something you do, make a custom exercise. It behaves exactly like a built-in exercise once it exists.

## Creating one

From any exercise picker (when editing a workout or adding an exercise mid-session), tap **Create a custom exercise** at the bottom. You'll set:

- **Name**: how it shows up in pickers and history.
- **Muscle group**: pick from the same flat list as the catalog (chest, biceps, abs and so on).
- **Equipment**: barbell, dumbbell, machine, bodyweight or other.
- **Default target type**: reps or duration. See [exercises](https://spartafitness.app/docs/exercises.md) for the difference.

Custom exercises are tied to your account. They show up in your picker. Other people in your group don't see them.

## Where they live

Custom exercises follow your account across devices:

- They appear on every device you sign in to.
- Renaming or editing on one device shows up on the others.
- Deleting one removes it everywhere, even if you do it while offline.

To rename or delete them, open **Profile → Custom Exercises**.

## Use them anywhere

Once a custom exercise exists, it shows up in the same picker as built-in exercises. You can:

- Add it to any workout template.
- Pick it as a [superset](https://spartafitness.app/docs/exercises/supersets.md) partner.
- Swap to it from a live session.
- Use it as the extra exercise when you add one mid-session.

History entries that reference a custom exercise keep working even if you later delete the exercise.

## When to make a custom one

Reach for custom exercises when:

- You do a variation that isn't in the catalog (different grip, different angle, a niche cable setup).
- You train a sport-specific movement that doesn't map cleanly to the catalog.
- The catalog has the lift but the equipment label isn't a great fit for what you actually use.

If you'd rather see it in the built-in catalog, send us a request. Catalog additions ship to everyone.
