Sue Harragan and Tawnya Christian didn't take their first ballet barre workout class together, but they had the same immediate affinity for the workout's precise movements and body-sculpting potential. Nowadays, they work together to spread the good word of the addictive workout at their Las Vegas studio, thebodybar(re). While their eclectic course catalogue includes TRX and spinning sessions, their core classes are all ballet-barre based. They mix muscle-building and core-toning with cardio and stretching for a complete workout that centers around the ballet bar. Some classes incorporate weights and adrenalin-boosting beats, and one even eschews the barre altogether in favor of a Pilates-style workout.
