Some people when they relate exercise to the idea of going to a gym or going to a sport and working out so hard after the training that it actually hurts. That's not the kind of health and fitness I am talking about. Some people do that and every now and again they will go to training, but in general the idea is to get enough exercise that is actually enjoyable without going to the absolute limit all the time.Muscle Rev Xtreme
I can relate this pretty well to the way that you look after a motor vehicle. If you always drive your motor vehicle to its absolute maximum performance, right up to the red line and then change, what you find is that your maintenance costs start dramatically going up.
