This is quite possibly the most retarded 80's slasher ever realized, but how can you be harsh on a film that features non-stop images of dozens of gorgeous ladies with exhilarating bodies doing aerobic exercises, taking showers and wandering about in tight gym outfits? Prior to being a horror film, "Aerobicide" is a 90 minutes promo video to encourage the use of steroids, silicons and other body-stimulating fitness products. If you'd leave out all the footage of hunky boys lifting weights and yummy girls wiggling their butts and racks to insufferable 80's tunes, there probably only have about 15 minutes of story left. Plenty of time to improvise a plot about a sadist killer slaughtering young health-freaks with a big safety pin (yeah). The film opens with an unintentionally hilarious scene of a girl getting fried between an electric sun-bathing device. Several years later people turn up dead in the same spa. You don't really need to be an experienced horror fanatic or a rocket scientist to figure out there's a link between the murders and the burning incident, now do you? Investigating the case are a seemingly braindead police officer (and Charles Napier look-alike!) and a beefcake private detective who gets lucky with the bustiest 80's beauty I've ever seen! Looking through the credits, her name's Dianne Copeland apparently, and she didn't do anything else apart from this turkey and an imbecile Troma-movie called "Surf Nazis Must Die". What a wasted opportunity! She may not have been a great actress, but she sure had two other BIG advantages that would help her move upwards in show business. The amount of gore and the quality of the make-up effects are nothing special, neither. We're treated to a couple of bizarre stabbings with a pin and some barbecued human flesh. The plot twists near the end are ridiculous and predictable, but by that time nobody is taking the film seriously anymore, anyway. "Aerobicide" (a.k.a. "Killer Workout") is recommended in case you want to switch of all your brain functions off for one night, but nevertheless feel like watching a film! It actually would make a terrific double-feature with "Death Spa". Both films have a lot of sexy and scarcely dressed babes  and both films are pretty dumb.
