I used to Apple fitness but it’s so expensive it like $9.99 a month.

I usually go on my runs in the morning. I find the sunrise to be energzing. To stick with it I recommend going to bed the night before early enough so you get enough rest. Give yourself a small reward after your morning workouts. Like a protein snack or something. You can try a pre workoitRemember each day you show up is an accomplishment. I would try working out in the AM every other day until your body gets used to the shift.
