The initial screen displaying anatomical illustrations of muscle groups and the search bar.

The video starts with a screen showing different muscle groups (chest, back, legs, glutes, shoulders, biceps, triceps) with anatomical illustrations. A finger taps on 'Beine' (legs). The screen then transitions to show four different exercises for legs: a sissy squat, a deadlift, a lunge, and a hack squat. The exercises are shown with anatomical overlays highlighting the muscles being worked. The video then shows a series of exercises for the back and glutes, including hip thrusts, bent-over rows with dumbbells, and back extensions. Finally, it shows an end screen with the app logo and text encouraging users to download the app to shape their dream body, along with app store ratings.
