It is no great secret that every person has a different level of physical flexibility. There are people that will likely never do the splits or anything resembling the splits in their life. Generally speaking, those kinds of people are classified as inflexible. There is nothing wrong with being inflexible; some bodies are meant to bend more than others. There are people that are flexible if they work for it a little—that is rather normal. Then there are the people that go beyond the normal spectrum, the contortionists of the world. Those people are classified as hypermobile, or having unusual flexibility where joints can move past their normal range of motion.
