Some people may be more flexible than other individuals for a few different reasons. For example, in females during pregnancy the elastin hormone is released to allow the body to take on the shape that's necessary to accommodate the foetus, and so the elasticity or the flexibility of the body will change during that gestation period. Sometimes people's bone structure just allows them to be more flexible, simply because of the way that the joints and the connective tissue align and connect to the bones themselves. Sometimes people just work at it more; they start at a very young age and their body adapts, and then they can still carry forward some of that flexibility for a number of years, even despite reduced activity and flexibility training.
