If you can't change your life to manage one hour of exercise for your health, longevity and wellbeing every day, there is something significantly wrong in your life that needs to change.
100 hr weeks is not healthy. If you make extra time around work to get the steps in then it's still not healthy. Up at 5am and home at 9pm is not healthy.
I know it's easy for me to just say 'you should work less' without knowing anything about you or your circumstances, but it sounds like you should definitely be prioritising your health more.
Can only echo @Stonehedge there
