Spirals - what is it?

[sooperdooper]

Just that really, my gym have started a new class called Spirals and I have no idea what it is! I could ask them, but I feel a bit daft :)

Spirals is a license free group movement workout program set to inspiring and motivating music chosen specifically for each individual section. This program is for everybody incorporating choreography that is designed to focus on specific styles of both dynamic stretching and stability challenge.

Thank you! :)
