STEP 1 · BECOME A MEMBER

Sign up and join in

The challenge is open to CORE members: enter your name and email once, free of charge. That is also how we send you your progress and your discount. Already signed up? Then you are in automatically.

THE IDEA

One or two classes a week. That's all.

No boot camp, no pressure. One or two fixed sessions a week, for ten weeks – right when it gets dark outside and cosy inside. Your body will feel the difference, and you start the new year stronger.
