Everybody's goal when they work out is to get results. Sure, some people hit the gym or put in that INSANITY DVD simply for the joy of it, enjoying the exercise and sweat as its own result, but most of us (c'mon, all of us) are doing it to get results. Lose weight, gain muscle, improve health, stay young, gain flexibility, train for a sport, something, anything. Now, we know you don't get results straight away, nobody really goes to the bathroom mirror the next morning expecting to see a radical change, but all of us relish that deep ache that we get in our muscles after a good workout. That smoldering burn that makes us wince a little as we go about our day, that we wear as a badge of honor. We love that burn, but at what point does that burn become pain? How do we know when to stop? Or should we push forward, into that pain, and perhaps get more results?
