Body building is the use of hypertrophy coupled with increased protein intake and/or steroids (NOT RECOMMENDED) to increase muscle mass. It uses targeted exercises to encourage single muscle growth.
Unfortunately, it does not lead to any meaningful performance gains for sports, real world activities, or combat. As such, it is the wrong sport to encourage at the national level.
Modern day science has now produced the fields of Strength Conditioning and Functional Training. I would love to have these cutting edge techniques to be promoted in Pakistan. In Australia, we now have dedicate gyms where people can benefit from them cost effectively.
Also, Ronnie Colman is a pathetic man who couldn't run on his legs if his life depended on it. He is no role model to be followed.
