Next Challenge starts April 30th 2018



We believe being at your optimal weight and oozing with energy is a fringe benefit of being healthy and fit, so that’s where this transformation challenge puts the focus.

We also believe that the road to being healthier and fitter should be fun, injury free and as easy as possible.
