While exercise is a great way to start the day, sometimes you just don't feel like it but the time still needs to be spent productively.
I installed a randomizer app on my phone that has (so far) 8 activities to spend the 30 minutes each day I'm getting up earlier to be more productive and healthy: run, read (print, not computer), clean, home improvement, learn, yoga, write (journal or work on an article), rest.
Unless I strongly feel like doing one of the activities, I randomly select an activity each morning.
