I'm guilty of making too many resolutions and getting overwhelmed really quickly. Luckily I've found great ways to make sure I don't flop before January ends.
1. Decide what's realistic
By this, I mean if you're like me and write down 20 things you want to work on, pick your top 5 and focus on those first. You can always add more once you feel confident with your baseline.
2. If you mess up, turn it around the next day
It's easy to quit if you miss one workout, or eat unhealthy for a day. The one meal turns into a "cheat week," then you'll feel like there's no point anymore. Don't let this happen! Remind yourself you're strong, and you can turn around your mentality the next meal, or work harder during your next workout.
3. Use a buddy to hold you accountable
I love using my friends as inspiration. I love working out in the early morning, but physically getting up is never easy. My roommates and I coordinate workouts, and it makes us go a lot more than if we were to be on our own.
4. Revise your goals if needed
If you realize you set the bar too high, lower it. It doesn't make your goals any less worthy, it just means you can slowly work up to your OG goal. Much better than just giving up.
5. Remind yourself why you made them in the first place
Doing this will help you focus yourself on the goals you really find important. Reminding yourself why certain changes are important to you will give you a bigger drive to sticking to them.
