Josh Dueck was involved in a terrible skiing accident in 2004 while attempting a difficult stunt that left him paralyzed from the waist down. Following his recovery he was anxious to get back out on the snow, skiing with a device made especially for paraplegics called a Sit Ski. As he got more confident in his skiing ability he began dreaming of doing once again what he has always loved to do, back flips. After a considerable amount of time training, you will see Josh, seven years after his tragic accident, pull of the first ever back flip in history with a Sit Ski. Congratulations Josh for continuing to pursue your dreams!
