It's a cruel joke, really. You push yourself and remain dedicated to the cause of being and living healthy and your body, inexplicably, decides that what you're doing is good, but not good enough. So, what can you do about it? How do you reach that next level of fit without driving yourself absolutely bonkers?
Well, one way is to change your regimen. This is something that I have suggested before and feel very confident is a great way to get over that proverbial hump. But, more than that, you have to get over the drama of the new attitude you've acquired from becoming so fit—your ego changed right along with your body. Trust me.
You have to reconfigure your goals once you hit that plateau (or wall as some say) and ask yourself what you want for yourself and your body now? Are you still simply trying to live a healthier life or are you looking for the physical manifestation of all your efforts—fitting into that size "whatever you want" pair of jeans or cocktail dress? It's an important question to ask because, quite honestly, the vast majority of us can always be fitter and eat healthier—these are things that are rarely overdone in today's fast food society.
So you have to look at yourself in the mirror and ask what's next? If you want to get over the plateau, that's easily done, change your workout and/or add something more to it that will challenge you and re-energize your bored body.
On the other hand, if you are looking for something deeper—perhaps an answer to why you are so obsessed with looking perfect or losing that last few pounds—then that journey will take a much more introspective approach and you will need to tap into the side of you that isn't satisfied with being what you are right now.
The only way to do that is to meditate, relax, journal, and seek out the memories that scare you to death. Find out where it was in your life that you first began to feel those inadequacies and make it your mission to correct the negative thoughts so that you can finally focus on the present.
In the meantime, expect setbacks as you tackle new obstacles and try not to get frustrated by the process of making adjustments to what was working so well before now—if you can. Being fit is only half the battle, the bigger challenge is in staying fit and being aware enough of your inner self to understand why that matters so much to you.
