Use the same approach as tighrope walking: don't look down.
After falling off the Healthy Lifestyle wagon repeatedly over the last
few weeks months decade, I'm Starting Over (again). So today it's "Day 1" (for the 20th time) of my John the Baptist Diet. Yeah, it's kind of insanely optimistic to start a new health-program in Advent, but if I don't, I literally won't have anything to wear to church at Christmas, except my bathrobe.
I'm also trying to get more exercise (that shouldn't be too difficult, since when you're doing "zero" there's nowhere to go but up), and if I post about it here, it should keep me somewhat accountable. Today I did about 20 minutes of cardio on my rebounder.
Stay posted for further elaboration.
Mine is cheap and doesn't fold. I think I'd like to get a better one someday.
