The actress is reviving the ’80s aerobics craze — a fad she fully embraced during that decade — in Pop TV’s Let’s Get Physical.
“I used to do aerobics back in the day,” she tells PEOPLE in this week’s issue. “I frizzed out my hair, had the headband, the leotard that came right up to your waist, the belts.”
And Seymour, 66, drew upon her experience from that decade for her latest role as a zany mom fighting a rival gym alongside her son, played by Matt Jones. “I showed them photography I did back in the day with a big mane of frizzy hair,” Seymour says, referring to her costars. “They literally freaked out. It couldn’t be more authentic if it tried.”
