I suspect he is using his musculature to try to establish his bonafides as a fat-loss guru bec.he believes it potentially more profitable at this point in time. There is a well-known "strength guru" that touted bodyweight exercises alone as the key to fitness/STRENGTH USING his special exercises with clever names. On the cover of his book he is shown with the muscles from his weightlifting days when he was touting the iron game. Bait and switch.
To paraphrase ano ...an open mind is like an open mouth
made to be closed on something solid.
