Local ladies have been buzzing about a challenging workout that helps achieve the long, lithe look of dancers. Barre Evolution, founded by Nicole Wallen and Nancy Meyer, is a Mt. Pleasant studio that incorporates ballet techniques using a barre to give a full-body workout. It's based on the Lotte Berk Method, Core Fusion, and Physique 57. It's not a dance class — it incorporates interval training, stretches, and slow, controlled movements. Devotees might be walking funny the next day, but it doesn't take long before they've got something to show for it.
