I whole heartedly disagree. Size, weight does not equal strength. Period. And to think one can increase his strength via increasing mass is incredibly misinformed.
Take a Judo practitioner for example, or any athlete that has to be within a certain weight range. It isn't always the biggest, largest athlete that wins.
That is just a single example but lets look at the logistics. If one affiliates weight gain with strength, why wouldn'y an obese person be the strongest man in the world?
Of course we can't speak on behalf of the entire population, but then one would also have to at least ponder why the biggest man in the world isn't the strongest man as well. And that is simply because size does not equal strength. Period.
Of course an ox is stronger than an ant, but an ant, for its weight, its stronger pound for pound in its arena. And when you speak in terms of combat sports, an athlete's strength is not indicative to their size... Including many other sports..
So then why do we attribute size to strength in lifting weights?
It's a premonition that has been bolstered by pseudo trainers who regurgitate scientific information in their own words. In other words, people translate facts, into guesses.
