  • Tanning bed (spoiler, this doesn’t really pay off)
  • 80’s product placement
  • Creepy guys hitting on the women
  • Ominous music
  • Overtly sexual aerobics moves


  • “♪♪ Animal Workout ♪♪!”
  • “Tell that college boy that if he doesn’t have that report ready in 30 minutes, I’m going to go over there and do an autopsy on his face!”

Viewer Quotes

  • “Was that batteries and condoms in her purse?”
  • With that hair I’m glad she’s dead.”

What We Learned

  • Safety pins are deadly weapons
  • Leaving a jock strap in a locker was a great come-on move in the 80’s
  • Multiple homicides will not close down a gym
  • Jean shorts and a singlet are a good clothing choice when breaking and entering
  • One cop is enough to cover / solve an ongoing murder spree

Final Take

Wow. Where to begin with this one? So the premise of this movie is that an aspiring model (Valerie) was badly burned in a tanning bed accident, but then faked her death and posed as her twin sister (Rhonda) while operating a gym / aerobics studio. In between gratuitous workout montages, gym members are murdered in creative ways, most often with a giant safety pin. Meanwhile, the police and authorities don’t seem to care enough to try to solve the mystery, or shut down the crime scenes (workouts begin immediately). The big reveal at the end, is that Rhonda is the murderer, who wants to kill attractive people because she is now bald and scarred from the accident. Somehow she gets away with it since the guy who was in love with her takes the blame (and then she kills him). The cop who knows she was the killer attempts to kill her, but due to incompetency, ends up getting killed, and Rhonda is back in business (and planning to start killing again).

This was a lot of fun- lots of gratuitous nudity, and complete absurdity with how the community treats serial killings. Why did she need to fake her death and pose as a twin in the first place? Was there no actual record of the death? Is it that easy to create a fake identity? But more importantly, how is it a successful business model to run a gym and murder your members? If it isn’t enough to kill your source of income, I think eventually the reputation of potentially getting murdered there would drive away business, right? Don’t overthink this one, just enjoy it!
