How do working parents do it?

Hi everyone! I’m new here and interested in trying to get to 10K steps a day. I am trying to lose about 15 pounds and I’m overall a pretty active person - I run and have a peloton bike. I would love to start walking more but I want to know HOW do you all find the time?! I am a teacher and work regular work hours and I also have a 3 and 5 year old. I usually work out early in the morning before my kids get up and then after work I’m usually so tired that it’s hard to motivate myself to walk. Do you just push through exhaustion to make it happen? Should I replace my other morning workouts with just walking? Any advice, especially from working parents would be so helpful!
