Talk to 10 people and you'll get 10 different opinions on what is fit and the best way to become fit. One will tell you to attend an aerobics class, another will swear by jogging, while the jock at your office will tell you the only way to do it is with weights. The truth is, being fit can come in many different forms. If you saw a person rock climbing up the side of a cliff, you would probably say that they're fit. Or if you saw a triathlete just finish the Ironman, you would guarantee to think they were fit. But if you put one person in the shoes of the other, your image of that "fit" person may change. The rock climber would not be able to finish an Ironman, and the triathlete probably wouldn't have the strength to climb a mountain. Too often thin is mistaken for fit, and that's not what you should strive for. The triathlete is probably very thin because they don't want the extra muscle to carry around during a long distance event. But their cardiovascular ability is operating at an exceptional level. Whereas the rock climber will still be thin, but have more muscle and strength in order to pull themselves up a cliff. In contrast, a NFL lineman is far from thin, many weighing over 300 pounds, but wouldn't you say they are fit? So if there are so many different versions of fit, how will you know if you've reached that "fit" level? The answer is it all comes down to what your lifestyle entails. Are you an athlete and you want to compete in a variety of events per year? Then your version of fit will need to consist of a lot of endurance training, strength, and stamina. However, if you're just a stay at home mom who wants to play with her kids and still have energy to do laundry at night, then you won't need to go to the same extremes as the triathlete. But what do both of these people have in common regardless of their lifestyles? Passion to push themselves to become better! Yes, a person who is fit will have good blood levels, a low resting heart rate, blah, blah, blah; but in my eyes a person who is fit is someone who can handle life's struggles, but also realizes there is always room for improvement. The triathlete who pushes himself up that hill a little harder. Or the mom who wakes up early for a run so that she'll have time to play with her kids after school. They are both fit in my eyes. Fit is not a plateau you reach and then you all of a sudden stop. Fit is the feeling your body gets when you know it is capable of conquering anything. And not just conquering it, but demolishing it with a smile! So if you don't feel you're "fit" yet, keep striving; keep pushing; keep working to be 1% better than you were yesterday. Then when you think you've reached that "fit" level, keep going!
