Wake up and put on your workout clothes. Your entire day will go differently. If you're out with the children and you're looking for an hour activity, suddenly the park or a local tennis court will be an option because you're wearing the proper gear (not kitten heels!). You're likely to take stairs or park far from the mall entrance because you have the shoes to get you there.
This doesn't mean that you stop dressing up and looking hot! You also don't have to spend a fortune to get great gear. This just means if it's a relaxing day without much planned, start the day off in your workout clothes and running shoes. Getting the "5" minutes in of exercise will be that much easier.
