Valerie's tragic tanning salon accident two years back sets the stage for this wild ride. Now her twin sister Rhonda is managing a trendy gym—but something sinister is afoot. Bodies start piling up at the fitness center in this gloriously campy 1987 slasher. Directed and written by David A. Prior, featuring Marcia Karr, David Campbell, and Fritz Matthews, Killer Workout delivers exactly what the title promises: murder, mayhem, and unintentional laughs. Perfect for cult horror fans who appreciate their thrills with a side of cheese.
