I guess you have to find within yourself a compelling reason to rise early and exercise.
Behavior change is possible. It’s challenging but possible. No offense intended with the following statement, however, it is not as though you are trying to change a behavior that requires a clinical approach.
Write down on a piece of paper the pros and cons of rising early and exercising and ask yourself whether the manner in which you are approaching engaging in physical activity is effective.
If you find that it is not, then, I would set a goal of a maybe getting up early in the morning, let’s say 15 earlier and start with stretching. Make that a habit and build from there.
I hope this is of help to you.
