"One hundred days, 100 nights to know a mans heart" goes the opening lyrics of Sharon Jones And The Dap-Kings song featured in this video focusing on heart health.

The ad by Argonaut stars a protagonist who sees a woman out of his league, fitness-wise. While she is able to runs the streets, he struggles to keep up.

Using a Fitbit wearable to track physical activity, he makes progress toward keeping up with her. By following his heart, he strengthens it.

Highlighted in the ad is the Fitbit PurePulse, which measures heart rate.

The dialogue-free spot will appear in North America, Europe and Asia.
