My understanding is that the term as it applies to muscle and fitness is derived from the old wooden farm equipment yoke that oxen where paired together or farms would use to carry heavy things like water pails.  It began being used in reference to individuals who had large backs/traps.  I could be wrong and the term could have something to do with eggs though, you learn something everyday amirite?
