For stretching exercises being able to change the cover photo
For stretching exercises when I custom upload the video being able to change the cover photo is important. When we create an interval workout the video holds still sometimes in some awkward positions for at least a minute.
Clients don't want to have to always play the video. A good still image of the static stretch would be enough but at the moment it looks really unprofessional and there is no way I can see to change this.
