Need feedback on a workout app’s sharing feature [on hold]

I need some design/UI feedback. I made this web page that we are using as a sharing function for our workout app. Users will be able to share workouts they've authored so other can try them, or share past completed workouts to share their progress.

That's the goal for the user.

The goal for the business is to promote a couple calls to action 1) traffic to the size/social media pages on the top, and/or 2) traffic to the app store links on the bottom.

Given the goals of the page for the two user groups, what is your opinion in terms of how we can improve the UI to best achieve these tasks? I for one think we should change the preview image, that's for starters. Should we change the preview text? On the page, anything about the content?

Thanks in advance
