I’d love for you to take this “chat with your coach” even farther and more engagement like at the end of a set let me swear at my AI coach like, “I hate you!” “F off this hurts!” Hmmm...maybe only I do that with my coaches?

I recommend you consider combining this with the other recommendation around 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 like this via Apple Watch integration.

What exactly is expected between the set counter and the pause timer? Perhaps a little status bar that tells me “Pause for 40” then when it dings it can change to “Do the set”.
