So, i convinced a friend of mine to try the sport one season ago. Now, a year later and he is still stuck in the heel side movement all absolute beginners learn, i.e. he is using the board perpendicular-wise to the slope to slide down. The nose is not used almost at all. I have advised him once or twice to try the leaf movement as this will force him to kinda point the nose of the board downwards to no avail. I think he's afraid of the speed as he tends to lean back whenever he picks up some speed whenever he tried learning on a nearly flat surface. How can i advise him to get better without sounding like an a$$ or like his mother?
