VAULT ENTRY: Killer Workout (1987) – Where Aerobics Meet Absurdity

 


Welcome back to the Vault, where we unearth the most bizarre, brilliant, and sometimes bewildering relics of horror cinema! Today, we're lacing up our high-top trainers and stepping into the neon-drenched world of 1987's Killer Workout (also known by its equally fitting original title, Aerobicide). If you thought your gym routine was tough, wait till you see what lurks in Rhonda’s Workout!

The Premise: The film kicks off with a memorable (and slightly ridiculous) bang: a young model, Valerie, meets a fiery end in a tanning bed. Fast forward five years, and her supposed twin sister, Rhonda (Marcia Karr), runs a bustling, spandex-filled aerobics gym in Los Angeles. But beneath the leotards and synth-pop beats, a dark secret simmers. Soon, members of the gym start turning up dead – brutally murdered by an unseen assailant wielding... wait for it... a giant safety pin. As Detective Morgan investigates the string of bizarre killings, he uncovers a twisted web of jealousy, vanity, and a past that refuses to stay buried.

Why It's a Cult Classic (and a Vault Favorite):

  • The '80s Aesthetic: Killer Workout is a time capsule of 1980s fitness culture. Prepare for endless aerobics montages, high-waisted leotards, questionable hairstyles, and a pulsating synth soundtrack that perfectly captures the era's energy. It's pure, unadulterated nostalgia, for better or worse.
  • The Absurdity: This film fully embraces its B-movie status, and then some. From the truly baffling choice of a giant safety pin as the primary murder weapon (which somehow manages to be surprisingly lethal) to the over-the-top acting and often nonsensical plot twists, Killer Workout offers a unique brand of unintentional comedy. You'll find yourself laughing as much as gasping.
  • David A. Prior's Vision: Directed by B-movie prolific filmmaker David A. Prior (known for other low-budget gems like Deadly Prey), Killer Workout showcases his distinctive style. It's raw, unpolished, and proudly independent, relying on atmosphere and sheer audacity over big budgets.
  • That Ending! Without giving too much away, the film’s finale offers a truly bonkers resolution that solidifies its place in the pantheon of "you have to see it to believe it" cinema. It's a testament to the film's commitment to its own wild logic.

Why It Belongs in the Vault: Killer Workout isn't high art, nor is it a masterclass in suspense. But what it lacks in polish, it makes up for in sheer, unhinged charm. It’s a wonderfully weird slice of '80s horror that encapsulates everything delightfully silly and surprisingly entertaining about the era's straight-to-video slashers. It's the perfect film for a movie night with friends who appreciate a good laugh with their screams.
