# Coaching on Saturday

These docs are for **coaches** using the Saturday **[coach portal](https://coach.saturday.fit/dashboard)** — not developers. (Building an integration? That's the [API Guides](/introduction) tab.)

Saturday handles the fueling so you can focus on the training. This tab teaches you the whole coaching surface — and, just as importantly, **how Saturday thinks about nutrition**, so you can answer your athletes' fueling questions once and for all.

## Co-piloting, not locking

You are **co-piloting**, not locking. Everything you adjust for an athlete — their fueling **Setup** (open an athlete from your **[roster](https://coach.saturday.fit/dashboard)**), their **[alerts](https://coach.saturday.fit/dashboard/alert-settings)** — syncs to their app instantly, the athlete is always notified, and the athlete can always change it back. The relationship is high-trust by design: Saturday does the math so you and your athlete can both see the same picture.

<Note>
  **You're also an athlete.** Every coach has their own Saturday athlete account. You can flip between your **Coaching** view and your **My Training** view with the <AppAction path="/open-app">persona toggle</AppAction> in the app — same account, two lenses.
