It can be rather difficult especially with young children. Working around nap times and getting a sitter if you can or going to a gym with childcare. Just when you get into a routine nap times change! So what do you do? Make adjustments. Perhaps you dust off the jogging stroller and take the kids with you. If you have older kids they can ride their bikes while you run. You can also do some activity that the family can do together.
You still have to work around the same issues but your body and your health will thank you. Keep your health a priority and your children will see how important it is too.
