154 - Killer Workout

Your Stupid Minds reviews a classic of the gym-based ‘80s slasher genre, Killer Workout, also known as Aerobi-cide.

An up-and-coming model (Marcia Karr) is horrifically burned in a freak tanning bed fire. Two years (or is it five years?) later, her twin sister Rhonda (mentioned only in online synopses) opens up a gym where babes and hunks are murdered with a comically large novelty safety pin. A needlessly confrontational investigator, Lieutenant Morgan (David Campbell), is assigned the case. Another hunk, Chuck, (Ted Prior), is sent by the gym's senior partner to work at the gym, and also knows white guy karate.
