So why are Lisanna and Natsu still having their hands behind their backs?

Those chains are long enough that they should just be able to pull them below their feet to their front. I am very far from benig an athletic person and even I can do that, so why can't Natsu, who's shown some pretty amazing agility during his battles and Lisanna who also seems rather nimble?

Now if the chain between the shackles would be shorter or higher up on their arms, I'd understand, but like this it makes little sense.
