I'm thinking of waking my neighbor up at 6:45 AM via working out.
Is there a reason you want to work out at that hour and wake them up?
If I did so, I will get into the perfect shape I've always wanted.
You shouldn't disturb your neighbors on purpose. If you do then they would want revenge by disturbing you.
Secretly, I will enjoy it if they wake up early to protest.
I love that you want to workout more, and it can be great early. However, I urge you to not disturb your neighbors at that hour. Have you considered a quieter type of workout at that hour?
