Allow certain clients to add videos directly onto session feedback.
Allowing clients on certain products to upload their videos for feedback, directly to the session, would provide a neat calendar view for the trainer to make feedback seamless and all gathered in the same place.
Give clients the ability to record and upload form videos directly into their workout results. That way they are saved into their profile and the client (and trainer) can look back and compare videos for progress checks.

I'd like to film my client's technique and attach it to that workout and then be able to refer back to it the following weeks to show improvement over time. This would be useful particularly for squat, bench and deadlift but any lift requiring ongoing specific technical coaching
In the clients programming, have the option of the them to video each set of the exercises for coach technical feedback. Like the True Coach program feature.
