Winging is neither particularly difficult nor particularly exhausting. You don’t have to be a top athlete or fitness crack, because it’s more about practising a technique that doesn’t require a lot of effort. So, Winging is a sport for everyone! So if you feel reasonably fit and have a healthy level of self-confidence, then you can start tomorrow!
Your big advantage is that once you have mastered the handling of the wing, you can try it out in the water, snow and asphalt! Consider: For wingfoiling, of course you should be able to swim and not be afraid of deep water.
