Progress pictures
I recommend you consider taking pictures. What if the app showed the last picture you took and said “This is your last progress picture! Time to take a new one! We’ll do it after your workout so make it count!”

I'd find it beneficial to upload a before and after picture. I don't know how big your staff is but a problem area that someone might have could be pointed out and then the AI or someone can tweak the workout accordingly.
