Why bother? Because even if your team doesn't "win," you still "win" by trying to keep up an exercise regimen and supporting others to do the same. You still "win" by proving to yourself that you are worth the time to be taken care of. You still "win" because you've tried to push yourself to limits you never thought you would even come close to.
Take it from me who three months ago couldn't lift 2 lb free weights without breaking a sweat and didn't know the difference between a dead lift or a bicep arm curl. You see, I've always been, an unhealthy skinny person. If you looked at my BMI (Body Mass Index), I fall well within the healthy range. However, before three months ago, I only really exercised in high school. During my college years, I held 3 different jobs and carried a full course load. I survived on a macaroni and cheese diet (without the cheese). So, while others gained the infamous freshman fifteen, I was at my lowest weight ever. Then, when I started working in the corporate world, the concept of corporate lunches and dinners took on a life of its' own. With back to back meetings, the only way to squeeze another meeting out of me was to make sure it was a "lunch" or "dinner" meeting. Despite the corporate meals, I still stayed within 10 lbs of my college weight. But, I FELT horrible most of the time. My body craved the exercise (I just didn't know it). Now caring for two kids, one would think I have less time than ever (I do). It doesn't stop me from exercising. I needed to go back to my high school mentality of what kept me emotionally and physically challenged,... I need the exercise.
So I know most probably I won't be part of the "winning" Get Fit Club group (I might be the reason my group loses since the "winning" criteria is based on # of lbs lost from start to finish). However, I'm a winner for exercising. I hate driving to the gym, parking the car and changing into gym clothes, etc. but I try and exercise there because the post-exercise high is worth it for me.
Studies have showed that if you exercise for external reasons, you will stop eventually, but if you exercise because you ENJOY it, then, you will keep it up. So choose an exercise regimen that works for you (group exercise for the social bugs), competitive races (for those competitors out there) or walking (for the zen lovers). Choose what works for you and just do it.
