LOUISE: Or striptease aerobics …
MADELINE: It’s really big in L.A. You just go through the motions, you don’t actually have to strip.
Striptease aerobics has its origins in pole dancing fitness classes, which first began in a studio in Canada in the 1980s, with the classes run by professional strippers. By the early 2000s, striptease aerobics had taken off in New York and Los Angeles, and often involved pole dancing as well. As Madeline says, normal fitness clothing is generally worn, there isn’t any actual stripping off.
