Hand over a program that really lands

A finished program isn't yet a successful handover. At the end of the appointment, take a short moment to open it together on the person's phone.
Show the QR code, let them scan it and open the first exercise. Point out the video, step-by-step images and timer if they've been added. A first tap together removes many hurdles before the first session.
Then don't just ask whether “everything is clear”, but when a realistic time to train might be. The reminder can be set up right away with suitable days of the week and a time.
That way the appointment doesn't end with an abstract plan, but with an open program and a concrete next step for home.
