What's inside

Everything a beginner needs, in one calm place

Every activity has a before, a during and an after: what to do, what you'll see, and a kind word for what you did.

Move a little, feel a lot better

Ten minutes counts. PETRA helps you fit it in.

Guided workouts

Know what's next, every set

Clear moves with sets and reps, a big rep counter, rest that waits for you, and “Next set” when you're ready.

How it works

Four gentle steps

  1. Quick safety check

    Three questions so PETRA only suggests what's safe for you.

  2. Tell PETRA about you

    Your goal, your time and your equipment. That's your plan.

  3. Follow today's plan

    Before, during and after: what to do, what you see, what you did.

  4. Celebrate and keep going

    Small wins, rest days and progress you can feel.
