Let us suppose you have a slim-n-trim physique with not an extra inch of fat anywhere, would you hit the gym everyday or at least occasionally? If this question was asked to a group of people then the majority of the answers would have been 'No', not because they are too lazy to hit the gym but because they feel that it is not required. Sadly, there is a common misconception that gym and exercise are only meant for obese or overweight people and that those who are lean and fit do not need to exercise. Well, physical fitness is a must for everyone, irrespective of their age, body shape and weight.
