Sorry, no etymologies found.
Callanetics has been around a long time though it is not that well known.
I don’t have a precise definition of a fad, but it seems to me that a fad lasts a season, maybe a year, and leaves little imprint when it’s gone – pet rocks, Beanie Babies, Callanetics, that sort of thing.
Around the same time, Universal produced the Callanetics exercise series as well as music videos such as the Doors’ Dance on Fire and Live at the Hollywood Bowl.
