AMERICAN BARRE TECHNIQUE is the BEST barre certification company.
I have used them for all of my barre certifications. Their courses are super convenient for me, since I’m always traveling while I teach barre. If you are new to barre, definitely enroll in the American Barre Technique Barre Instructor Certification Course. It’s all online, and you can study at your own pace. I have had much success since getting Barre certified with American Barre Technique and highly suggest you to go through ABT
