A good barre studio is judged mainly on the instruction. Barre classes are often small and built around short, repeated movements, so a trial class shows you how the teacher corrects alignment and adjusts moves for different levels. Good teachers explain what each set is working on and offer modifications for past injuries or pregnancy. Check that the floor, mats and any props are clean and well kept. Many regulars book a few classes before they commit to a package, so they can find a time and a teacher that suit them. Check the membership and cancellation terms before you sign anything.
Zubir Said Drive is near the Dhoby Ghaut and Bugis MRT stations and the Kampong Glam shops, so the studio suits people who train before or after work in town. For anyone in the neighbourhood, WeBarre at the School of the Arts is worth a visit to see whether its classes suit your routine.
