THE ORIGIN STORY
KILLER FITNESS: Where Fitness Meets Fear—and a Whole Lot of Fun.
From a young age, Ama, Kay, and Vanessa were drawn to the world of horror films, the infectious energy of dance, and the nostalgia of 1980s pop culture. What started as a shared obsession has evolved into a full-blown fitness phenomenon- with a killer twist.
Ama's journey began in the studios of the University of Southern Maine, where she danced ballet and jazz on a scholarship. But it wasn’t long before her passion for visual storytelling lured her into the world of filmmaking and allll the way to California. There, her lifelong love of horror and neon-drenched 80s aesthetics found fertile ground—and something more than nostalgia started to take shape.
Enter Vanessa: Actress, Artist, Influencer, and full-time Scream Queen. A fellow fanatic of the weird, wild, and wickedly retro, she and Ama teamed up to create what would become the cult hit, "Slashercise"—a VHS-style workout video dripping with camp, cardio, and an intense creep factor. They brought Kay onboard, a classically trained performer, proud theater kid and self proclaimed Zombie fanatic, to bring the on-screen sweat to life. Together, they unleashed their vision on the big screen at the Aero Theater in Los Angeles—and the sold-out crowd ate it up.
After the bloody good response and a flood of fan requests for live classes, the trio knew they had to take the next step.
And so, Killer Fitness was born—a brick-and-mortar workout experience like no other. Here, the rhythm of retro aerobics meets the pulse-pounding thrill of slasher cinema.

She is a stage siren and dance fitness sorceress with 20 years of experience conjuring cardio dance classes in Chicago and New York. Angie grew up watching Haunted Mansion and THRILLER clips in her high chair, and obeyed family rules like: “You can watch Pet Sematary until Aunt Susan hangs herself—then you have to turn it off, it’s too scary.” One childhood dance recital ended with her aunt explaining FX contacts over pizza… just before playing Satan on The X-Files. Angie wasn’t scared—she was sparked. Horror runs in her blood like glitter in a vampire rave. Angie believes movement is medicine, & that fitness should feel empowering. She strives to create spaces where all feel free to let loose & feel as alive (or dead) as they wish. Bring your sense of humor & a water bottle to her classes.
