I’m pretty sure Phil was commenting on the difficulty they had with the specific task- maybe loading something onto a boat and/or traveling on that boat somewhere? At very least it sounds like something where their height/weight would be at a disadvantage
I think Phil’s comments are more directed at the task than the leg as a whole, then he added the speed bump comment on top of that
I don’t even know if it confirms them actually having difficulty with the task in question, let alone the entire leg
For all we know, they could have crushed the task despite their size disadvantage, and Phil was amazed by that fear enough to comment on it
