A friend of mine successfully started a routine of waking up at 5am to go to the gym before work. His success was largely around setting an alarm to get ready for bed. He'd set an alarm to start getting ready for bed, and then another alarm when it was time to turn off the lights. The last 30 min or so before he went to bed was time to read -- no screens since he'd get distracted browsing websites and find it harder to fall asleep.

While he was starting off he kept the schedule fairly strictly, with weekends and meetups included. After he got into a routine he started getting a bit more lax, but I'm pretty sure he still has an alert on his phone some 2 years later after starting this habit.

I used to play basketball every morning at 5:30 AM. Did it for several years. I used similar methods to get my schedule to adjust as your friend. I never really shifted to a "morning person". The 500th day of 5:30 basketball was as hard to get up for as one of the first few.
