The tight and toned members of a high-tech health club really feel the burn─not to mention the stabbing, mutilation, and dismemberment─when the vengeance-seeking spirit of the owner's late wife takes over the equipment and gives everyone a "killer workout" in every sense of the phrase. Gore-filled exercise in terror stars William Bumiller, Brenda Bakke, Merritt Butrick, and Ken Foree. 87 min. Widescreen; Soundtrack: English. Two-disc set.
