I think he's talking about these ladders:
717593957175... You know, like the patterns you can find in Can Can.
Best thing you can do is to turn your body facing left or right and take them as they come. In that position, it's easier to make the ladders. It's up to you to find out where to turn to make this even easier (for me, I turn my body to the left and take the ladders in that way, since I can support myself more with my right leg).
