Taking sides is a part of human nature. God knows that politics and religion have spilled more blood and cost more lives than any other subjects in the history of man - but there is a close third: the distinction between exercise and training (I'm guessing the debate about squats might be in the top three as well). Anyway, most people consider them the same thing while they are very, very different. How different? How about the difference between success and failure?
What is exercise (check out how Wikipedia defines exercise)? It's any activity that gets you physically active (I guess golf should be included here but is it really exercise or an activity?). Exercise is not necessarily directed or goal driven and is more than likely a lone pursuit (think gerbils on a treadmill). Exercise is what you see being performed at your local "globo gym". Unfortunately people that exercise don't usually have the drive and support to continue at it for a long enough period to make a difference in their lives.
What is training (once again, see how Wikipedia defines training)? Training is goal driven (i.e., training to compete in an event or for a specific purpose) and is usually indicated by a high level of intensity or desire. The training mentality is such that you are practicing skills, techniques, and movements that will get you closer to accomplishing your goals (big focus on skill-based work in training). Mindless repetitions do not factor into training - it's about the development of good habits that lead you to great technical ability). Training usually occurs as part of a group or team that has similar goals in mind (kind of like martial arts or CrossFit).
So, which one do you do? Do you exercise or do you train? I know what my answer is - I train. I train to get stronger, more mobile, and more efficient. How about you?
