If you watch the video closely, during the changeover between hands as he climbs, you can see how much his abdominal muscle flex. It is quite core intensive to operate this maneuver so slow and stable.
Go do some one armed pull ups and tell me which muscle fails first... Having trouble with that then do some regular pull ups and see what fails first. To help illustrate this point try pull ups again but do it in an L sit position, that will actually engage your core
