This is a solid article, but the title is just wrong. "Free weights are better than machines" is not a "little known" fact, it's a well known fact by anyone who has cared to read the internet re:fitness since 2009. So is "lifting weights is much more efficient than cardio".
I say this only so that you don't read this and think these are some kind of fringe theories. They're widely, WIDELY known and 100% true.
