Popular 80s workout is seeing a revival.
Jazzercise is still kicking and skipping after all these years.
The legwarmers are gone though, as are most of the sweatbands.
"Jazzercise is a dance fitness program that provides cardiovascular conditioning, strength training," explains instructor Arlene Allen-Mitchell.
Ilene Shatkin has been a jazzerciser for about 25 years.
"Originally I started because I wanted to get in shape and it's blossomed into a lot more than that," she says.
Somewhere along the line weights were added for muscle training and strengthening, so it's not just a cardio workout.
It's still a high energy, high impact class that claims to burn up 600 calories in an hour.
