Hi! I'm Charlie and I work as a Wim Hof Method Instructor with my  husband, Radek Kalaš, offering Wim Hof Workshops in Sheffield, South Yorkshire.

We decided to offer classes and workshops together so that our participants get double the expertise, guidance and support and because we enjoy working alongside each other.

Between us we have over 30 years teaching and coaching experience and we are excited to be able to share the Wim Hof Method as part of our repertoire. 

My speciality area is 'breathing' and Radek's is 'cold exposure' but of course we are both committed to the full practice of the WHM. 

We both have a background in health, nutrition, fitness and wellness and I have a particular interest in endurance sports (running & cycling) and Radek in Martial Arts.

We are both interested in holistic or alternative medicines and how the body can heal itself through natural means just by changing the way we act and breathe. 

If you find that any of my Workshops are sold out, please check Radek's profile for extra places. We always run our Workshops together so you will be booking the same one. For his activities click here.
