This is an exert taken from the Riding & Staying Upwind video, which is part of the Progression Kiteboarding Beginner Collection.
The Riding & Staying Upwind chapter has over 30 minutes of instruction helping beginner kitesurfers move on from wobbly first runs, gain control of the board and kite, through proper edging, balance, stance and ultimately mastering riding upwind – saving you from the dreaded walk of shame up the beach in-between runs!
This video also has a blog post with more information on this technique:Shoulders Back, Hips Forward - The First Step Towards Going Upwind in Kitesurfing
