Avoid Workout Injuries
From some trainers ‘No pain, no gain’ really means ‘you should feel some pain’. While mild discomfort is to be expected, especially for those just beginning a new fitness routine, pain is a natural warning sign. Pay attention to it.
A good workout routine will test you, but shouldn’t damage you. As muscles get used, especially somewhat beyond their usual range, lactic acid, micro-tears and other physiological changes occur that result in muscles being built up stronger than before.
