New job that requires getting up way earlier than before

I'm about to start a new job, which I am very excited about. However, it's gonna require me to commute to a different part of the city and that commute takes a while. To get there by 9am, I need to be up at 5.30am. I am usually used to waking up around 7am and then having time to exercise and play my guitar before a long day of work. I know that there is gonna be a transition month for all this, but once I'm settled how should I make the most out of that one hour I'll have in the mornings? Ps: I dont want to wake up at 4.30am.
