can you tell we’re excited about our newest way to FORMAT ✨💛

here’s why you should be too:

• a beat driven class to help you get out of your head and into your body 👌🏼

• full body movements, expect more combination work and less isolated muscle focus than a barre class. for a total body experience.

• core work as a focus to keep you centered

• a focus on strong cueing and alignment to make you feel safe and strong in your body 🙌🏼

• unheated - cause we’re already hot 🤷🏻‍♀️
