Adjust workouts based on sleep the previous night, motivation, etc.

I think further integration with other data I have on my phone from other health apps would be great: heart rate variability, sleep the previous night, etc. would be useful. So, when I go to workout, perhaps the app says, you got only 6 hours of sleep, then asks me how much motivation I have to work out, and then, based on my responses, suggests a tailored workout, etc.
