Hi Gina! We're experimenting with on-demand videos. What you see at the top of the front page is a collection that we curated from a handful of trainers, then uploaded. We want to see if this kind of workout experience is something that consumers want in addition to the live and replay experience. The "top trainers" is an editorial selection based on popularity (views, followers, likes, etc...). In the future, we will provide guidelines that give all trainer a clear path to achieving this status. Hope that helps!
