The majority of people who become successful contortionists will start doing contortion in childhood. Generally, people will begin their journey to become a contortionist when they are around 8 years old. Humans are generally a lot more flexible during childhood, so beginning the journey to becoming a contortionist at this age really makes sense. However, that doesn’t mean that you cannot start this journey later on in life, it simply means it is easier if you start earlier in life.
