Also known as “Aerobicide”
At some point in the movie, someone spray paints “Death Spa” on the front of the aerobics studio where most of the movie is set — which is odd because that movie wouldn’t come out for another two years, and there isn’t anything like a spa in the aerobic studio.
This (barely a) movie is multiple sequences of tightly-clad young, attractive women doing aerobics, with a slasher murder mystery interlaced that is not really interesting. There is a definite spoiler involved, which I won’t reveal, but I will reveal it is kind of dumb. How the very end unfolds is even dumber, and when you think about it, is totally unrealistic.
