I could NOT have handled that Jordon Almond.
With all of my "starting over" experience, I have discovered some things that work and many things (obviously) that don't. Here are some tips from yours truly, but please keep in mind I am obviously no expert and this mostly serves as a reminder list for what I should be doing!
DON'T feel so hopeless (because it will seem that way at the beginning) that you just give up completely and go back down the path of drowning your sorrows in whatever calorie-laden grub you can get your hands the fastest.
DO eat! The worst thing to do is suddenly eliminate several food groups or vow to follow an absurdly restrictive diet.
DON'T copy someone's diet or workout routine because it probably won't have the same effect on you. Definitely use plenty of people and sources for ideas and motivation, but don't blindly follow your friend, roommate, yoga instructor or favorite celebrity.
DON'T start too strong. Whether you've missed a week or two months' worth of workouts, don't jump back in too fast because it will backfire.
DO set realistic goals that you can follow on a long-term basis (well, basically forever). Start slow and gradually work your way back; you'll be more likely to keep going and continue to improve your fitness.
DO learn to listen to your body. I never bother to listen to my body because my mind is always screaming, "TREATS!" But it was loud and clear last week when it was screaming, "STOP!" It is a process, though, so be patient.
DON'T just wing your workouts. Plan them at least a week in advance so they're built into your schedule and you know what you're going to do.
DO incorporate new classes, exercises, running routes, playlists, etc. They challenge your mind and body.
DON'T feel like you have to tell people that you're trying to make a change. A lot of people say it helps hold you accountable, and if it does, great, but you should be doing it for yourself in the first place, and that should be enough.
DON'T forget the power of sleep! When I get obsessed with making sure I follow through with every workout, I'll stay up until 1:30 AM if that's the only time I have to exercise....only to then get four or five hours of sleep and completely reverse any of those benefits.
DON'T get mad at yourself or overreact when you end up not making the smartest choice, whether it's skipping a workout or forgetting that portion sizes also apply to desserts.
DO forgive yourself because you will never be perfect . . .
. . . but DON'T make excuses. I can rationalize anything. Don't.
DO take care of and love yourself because you deserve it, and DON'T you forget that!
