Yeah, even the pros have off days. If it’s the off-season, they sometimes take a day off. Now it shouldn't happen that often, but we are all human. We all have bad days. Now if you’re training for a show, then you never take off unless you’re really, really, really, sick. But on the days that you have to leave, don’t give it a second thought. Your body needs rest. Some guys take months off at a time. You just roll with the punches. You go back the next day when you feel good and start over.
