Pick what you came for.

One answer, and the whole plan bends toward it.

Three minutes to a plan. Twelve weeks to a different photo.

  1. 01

    Answer a few questions.

    What you want to change, where you train, and how many days you have. Peach asks; it takes a minute.

  2. 02

    Get your week.

    Three sessions built around your goal, at the gym or at home. Every four weeks it gets harder, then gives you an easy week.

  3. 03

    Do session one today.

    Not Monday. Today. Your after photo starts the day you take the before one.

Three sessions a week. Twelve weeks to the photo.

Each one has a name and a job. A rest day shows the next one, and you can move it to today with a tap.

Inside the app

Nothing to figure out. Just show up.

The session.

It tells you what to lift and when to rest. You just do the set. The timer follows you to the Lock Screen.

Protein first.

Point the camera at your plate. The glutes are built in the kitchen too.

The after photo.

Same spot, same light, twelve weeks apart. The change you can see.

Meet Peach. She grows with every session.

Name her, put her on your Home Screen, and watch her change. She never shrinks, and she never blames you for a rest day.

Questions.

  • No. Tell Flex where you train and what you have. At home it builds around bands, dumbbells and a mat; at the gym it uses the machines and the barbell.
