we have the world freestyle kayak champion, nick troutman, via skype right this minute. did you choose this as a sport? >> my best friend's dad owns the largest rafting company on the ottawa river, and one year he said, hey, nick, i'm going to try kayaking, and do you want to give it a shot? and ten minutes into the boat, i knew i loved this sport and i wanted to do it for the rest of my life and i have not gotten out of the kayak since. >> you are doing some incredible stunt work or trick work or what do you call it? >> freestyle kayaking. that i are short boats to do tricks and the big waters and the waves make it easier to get more air. >> this is dangerous, and how long does it take to get to do this? >> well, i have been paddling for just over 10 year, and so it depends how much time and effort you put into it. >> nick, how much physical work do you have to do to prepare your body to do this? what is the regiment like? >> well, you'd be surprised you work out every now and then and go for the bike, but mainly kayak alone and paddling alone will keep you in shape. >>
