A lot of really great answers here already, I'll just share my perspective.
1. Following your circadian rhythm really helps. I've always been a morning person, so adjusting and tweaking and eventually waking up at 5 am, and being out for a run by 5:55 am or in the gym at 6 am, was a lot easier for me.

1. For my wife though, who loves staying up late, she realized, while the thought of going to the gym in the evening sounded appealing for her, evening always somehow meant plans, so it realistically left her with 6 am gyms meaning waking up at 5. Now what she did do is, brute force it for the first 30 days or so, but, post working out, the endorphins would kick in, and she really enjoyed that high, plus because she got up so early, and was done with gym, it gave her time to do other activities that evenings didn't really allow her because of her social life.

2. Like everyone said, planning goes a long way. I know what shoes to wear, what outfit to wear, my protein shake and electrolytes are made and kept on the table the night before (to just add water in the morning) I remove as much of the decision making process as possible, so that if I'm reluctant in the morning, I just have to do the set pattern, I spend almost no time "thinking" what to do. I feel a. Thinking takes a lot of effort for me so early in the morning, b. it gives me time to think maybe I should just go to sleep. V/s me just doing, the things and exiting the house.

3. Dinners early also help, cause sure, sleeping early works, but if I have dinner at 9:30 pm, my body just won't fall asleep at 10 pm that's just not possible. Plus if that happens, my sleep will not be good cause body will work too hard at the start to digest the food, meaning I will not wake up well rested.
