If this is not an option, it is always good having a gym at work or near work and exercising during lunch.
Sometimes you can just concentrate on the muscles you're using during the day…. Like pull your abs in when walking.
Or you can maje it like a game for your children and have a 10 minute exercise with them.
I’ve been using the app “Wakeout” on iPhone to do am energizing workout right after I wake up and it works SO WELL! But there’s a 7 minute workout app and tons more. Maybe experiment with short workout apps like the ones mentioned or Nike Training app
