Consistency is Key.
Once-in-a-while running isn’t going to make it stick as a habit. You need to get moving a few times a week. Set a schedule and hold yourself accountable to it. Or, find a friend to run with that will help hold you accountable. But be realistic.
Also, going from zero running to running every day isn’t something you can realistically maintain. Shoot for a couple of runs during the week and one on the weekend. Then, it’ll be much easier to up your mileage and frequency after you’ve made running a habit. — Mags
