Working class people how do you manage gym?

Hi all, I was just wondering how all you working class people with 9 to 5 jobs manage going to the gym? My work timing is 9.30 to 6.30 and travelling takes 3 hrs total. So I only workout 4 days a week(2 weekends and 2 days work from home) and that too at home and don't go to the gym. Do you have any suggestions for me ?
