I didn't, these are all part of the "8 hours for other things".
If you want to live far from your job, then you have a lot of commute, same for food if you want to take your time for eating. Working out is not mandatory.
You can always optimize time, I work 10 hours per day, I workout every day and I still have about 2 hours of free time per day
1. Getting ready
2. Commute
3. Eating
4. Work out
5. Errands
6. General daily stuff - calls, unexpected events
7. Family and kids (if applicable)
I guess during weekdays you don’t have spare hours more than 1 or 2 or at a stretch 3
