Why? Just take a look at the founder Greg Glassman — does he or has he even ever worked out? Highly dubious.
Also read his email — he seems like a foolish person.
Morale of the story:
Do not trust the methodology, philosophy or technique or product of a thing if the founder themselves are not a strong embodiment of their philosophies.
Google images Greg Glassman — looks like an anaemic wimp.
Also just take a look at his double chin.
