How do you schedule a 5 or 6 day/week workout schedule without life getting in the way?

I see posts from people who commit to 5 or 6 days a week workouts but I always wonder how life doesn’t get in the way of at least 1 day a week of that schedule. Currently I’m doing 3 days a week and there’s the odd time I can only do 2. Regardless where you’re doing the workout you still need to change, workout, shower etc which is time consuming. I’m a grown ass adult with 1 adult child. I work full time. I consider myself very low life priorities and still find this challenging.
