The bright yellow banner with "SUMMER SALES EVENT" and the Retro Fitness logo.

The ad opens with a bright blue background featuring a sunburst pattern. A yellow banner with the text "SUMMER SALES EVENT" is prominently displayed, with the "Retro Fitness" logo above it. The ad then transitions to show a person signing in with their phone at a payment terminal, followed by short clips of people working out in a gym. The pacing is quick and energetic, with dynamic visuals.
