The OED2 has the noun phrase “work-out” ("A boxing bout for practice; more widely, an exercise session, practice, or test") from 1909, the phrasal verb in the related sense from 1927.  No detailed etymology is give but “out” is often used as an adverb or part of a phrasal verb to indicate full (or fuller) extent, completion, conclusion, etc. (Hear me out, live out your days, fight it out, tired out, worn out, tough it out, ride out the storm, etc.)
