The best way to get back on board is to stop making excuses. Almost every day, I'm faced with some reason to skip my workout or stray from my dietary goals. Some people will say "Steph, you're no fun, you're always at the gym!! Even on a Friday night?!" Or "Dude, just eat it!! You can eat healthy tomorrow." They're all normal reactions and don't have bad intentions, but it's the way I react in those moments that have gotten me to where I am today. It's hard to turn down a Friday night party in the city or fries when you're out eating with friends (and I don't always do), but it's easy to be a yes (wo)man and want to please everyone.
While I'm constantly told that I'm lame for choosing not to drink or party, I'm also asked how I look and stay fit a lot. This is how- I make a plan and stick to it no matter what. I also don't spend a ton of time at the gym like people think I do, maybe at most an hour a day. I just do what I like to do in the amount of time I like to spend at the gym. As long as it's sustainable, it'll work. I've also given myself excuses multiple times, but I found a way to put fitness as a priority. I worked hard enough to see results, so I believe that what I'm doing is going to pay off. I put this before anything else that pops up throughout the day- it's nonnegotiable. If I planned it, I'm going to do it. If I find that there's a possibility that I'll have to skip a workout for some reason, I'll still plan ahead and assign it to a different day. It WILL pay off, it's one of the only things that is guaranteed in life haha.
You need to be honest with yourself, because the only person you're lying to is yourself. Are you really putting in the effort? If you don't care about your health or physique, that's a personal choice and that's ok, but if you say you do but complain about how it's so hard and make excuses, then re-evaluate your actions and make a better plan. It's never too late! Be patient and have enough willpower to put yourself first.
Also, I do go out and have fun, but just not frequently. Every time I do, it's an awesome time with good company, but now I just maintain a good balance between social life and swole life 😉
