Even as flexible as little Prompto is, (he likes to do yoga when he remembers to, he thinks it can be relaxing. Except that time he got his foot stuck behind his head…he decided not to do yoga alone and far from his phone anymore.) and he can truly get into some fun poses for you
Ignis is the most flexible of all the boys, with his acrobatics and stunning battle moves it comes as no shock
Noct is only as flexible as he is because Iggy forces him to do stretches regularly and sometimes during training as well
Gladio is probably the least flexible because that man is all muscles
