O'Brien, who also works with hockey star Sidney Crosby, reviewed Chan's diet and off-ice workout routine, down to his breakfast and post warm-up supplements, and provided guidance on other matters.
"[O'Brien] has experience with Sidney Crosby, who strives for perfection at all times, and I see myself as bit of perfectionist," Chan said. "It was good to talk about how to deal with the challenge to repeat as world champion. It was a very good week, a very productive week."
From there, Chan traveled to Toronto to work with choreographers Jeff Buttle and David Wilson on his programs, including a short to Rachmaninoff and free to music from La Boheme.
"We changed the patterns and even the order of some of the jumps," Chan said. "I felt I was struggling, mostly in the long program. [The changes] make it easier to be consistent with the elements."
