It is really a sad part of the fitness sport that any tom dick and harry want to become bigger and stronger like Ghuman or lean and muscular like Hritik Roshan. There are crooked people around, who always misguide the fitness enthusiast by promoting unscientific, laborious and baseless training and expensive supplements and health challenging drugs.
It has been proved that the effect of exercise, if done correctly and scientifically, is same on every individual but the outcome varies upon the basic physical genetics of the person. Similarly the supplements and drugs effects everyone but the outcome varies as per the natural genetics but the side effects are same with everybody.
Physique like Ghuman and other International stars comes from the huge frame, tall height, endo-meso structures. They are born and got the natural inheritance from the parents to have huge physique. The effect of exercise is much more on them than the poor people born with pure endomorphic or pure ectomorphic structures. Similarly, even if they take any assistant boosters in the form of drugs, steroids etc. the effect is definitely there. Where as same thing may not effect the people born with poor genetics even if dosages may be many times more.
Similarly, the physique like Hritik or other models comes from the people born with ecto-meso structures. These type of physiques if trained right, tend to get leaner and muscular but may not get bigger. Even the drugs, excessive training and cardio can never transform any endomorphic to ectomorphic. Though there are rare examples of physique transformation but once the person is out of training or not serious with eating habit and tends to loose the results.
So it is advised that never get fascinated or follow a champ because he is born with different and better genetics then you. Thus, Champs are born – and nurtured by good coaches.
