A feeling of fellowship with others, as a result of sharing common attitudes, interests, and goals
In CrossFit, you have several layers of community. You have THE CrossFit Community. That common bond you share with every CrossFitter out there. You have the Regional Community which, for us is the North Central Region. When cheering for someone at the Games, we always cheer for NC. Then you have what I will call Sub-Regional or Local Communities. This is the connection and bond you may have with boxes that are close to your own or in cases could expand to within your state. Then there is the Box Community, which I believe to be the most important community we are connected with.
This community, YOUR community, is a small group of people who you see for many hours a week. In some cases, it may where you spend most of your free time outside of the work place. Your community is even more special since you experience the same exact workouts as everyone else. Knowing that you and everyone else that attended that day did the same reps, weight and/or time. Your community is in a place where nobody is left out. You may be the fastest or strongest one day and the weakest or slowest the next. That doesn't matter though. What matters is that you all attacked the workout with 100% effort and finished. Your community is in a place where those who finish first don't always get many, if any, cheers but those who finish last always get the most cheers.
Your Box Community is a place where you can rely on others for support. Whether that is in a WOD, a lift, your diet, or an issue unrelated to CrossFit or fitness, your community is there for you.
