How did frosty-haired sex kitten K.C. Winkler come to inhabit such a bodaciously flab-free and fabulous body? The answer is that she spent years as "Body by Jake" Steinfeld's primary prop and shimmying shill. An infomercial does no good without ab-crunching K.C. dripping sex appeal like sweat in her skimpy, clinging workout togs as she demonstrates the bun-tightening, tummy-defining, rack-stretching techniques of the Body by Jake regimen. Is it exercise that Jake is selling, or sexercise? No such confusion exists in K.C.'s two best sexploitation stints. H.O.T.S. (1979) is a basic excuse for well-hung ladies to flail their dangling chest parts, and is there any doubt about what will be bouncing into view in The Happy Hooker Goes to Hollywood (1980)?
